Ti, GF116 to 1GHz frequency

"In the analysis we are going to deal with today's NVIDIA's GeForce GTX 550 Ti, a video card designed for entry-level market and characterized by the presence of 192 shader. For the development of new NVIDIA has pushed hard on the operating frequency: 900MHz reference in the proposal, without overclocking "

Introduction

È passata una settimana dalla presentazione ufficiale di Radeon HD 6990 , la scheda grafica di AMD destinata alla fascia più alta del mercato. Caratterizzata da due GPU sullo stesso PCB, la nuova nata rappresenta a oggi la scheda grafica più performante sul mercato: per raggiungere prestazioni da testa di serie sono state però necessarie importanti modifiche alla circuiteria di alimentazione e al sistema di dissipazione. Radeon HD 6990 è una fuoriserie in tutto e per tutto e, come tale, ha bisogno di un alimentatore capace di fornire la giusta potenza oltre ad uno chassis in grado di garantire una corretta areazione di tutti i componenti. Una scheda video dedicata quindi al segmento degli utenti che vengono defined enthusiast, a clear mioranza market. spent seven days and a new graphics card segment facing this tumultuous world of IT is called the GeForce GTX 550 Ti is developed by NVIDIA. The new graphics card is designed to get you to hit the mainstream market, with a very different position than then reviewed on Hardware Upgrade no later than 7 days ago. While the rise in the market for CPU with integrated graphics is eroding sales of the discrete GPU, it is true that the segment is to hit the entry-level solutions: graphics cards with computing power sufficient enforcement of basic operations, which do not involve direct benefits compared to a CPU with the latest generation GPUs. NVIDIA decides to play the card GeForce GTX 550 Ti: a solution characterized, at least on paper, by an attractive price / performance ratio and able to be a good way of updating your system. These specifications of the new form in comparison with other proposals NVIDIA in the mainstream market: GeForce GTX 550 you GeForce GTS 450 GeForce GTX 560 you GeForce GTX 460 production process 40nm 40nm 40nm 40nm type GPU GF116 GF106 GF114 GF104 GPU clock 900 MHz 783 MHz 822 MHz 675 MHz numero GPU 1 1 1 1 numero stream processors 192 192 384 336 clock stream processors 1800 MHz 1566 MHz 1644 MHz 1350 MHz ROPs 24 16 32 32 quantity memory 1024 1024 1,024 MB 1,024 MB type memory GDDR5 GDDR5 GDDR5 GDDR5 memory clock 4104 MHz 3600 MHz 4008 MHz 3600 MHz memory interface 192bit 128bit 256bit 256bit power connectors 1x6pin 1x6pin 1x6pin 1x6pin specifications highlight as GeForce GTX 550 We proves the direct heir to GeForce GTS 450: a signed NVIDIA graphics cards that have proved most successful in the market, in terms of volume. Developed with 192 cores and a memory bus 128-bit GeForce GTS 450 was made to go on the market to provide a solution for gamers who can not afford to spend large sums. In its process of renewal of the full range of graphics cards, having presented GTX 580, 570 and 560, the heirs of GTX 480, 470 and 460, so now is the time of GeForce GTX 550 Ti. Among the main innovations catches the eye memory bus, carried by 128 to 192 bits: an increase is necessary in order to increase bandwidth and improve overall performance of the graphics card. Like all solutions of the GTX 500 series, also in this case NVIDIA has made major changes in transistor to improve energy efficiency. The optimizations have been granted so significantly increase the operating frequency: this is when you work with GeForce GTX 550 frequency of 900MHz, nearly 120MHz faster than the GTS 450, with stream processors that clock frequency equal to 1,800 MHz dual The new baby at home is yet another NVIDIA card Fermi result of a variation of the architecture that was introduced on market only in 2010 has also been able to recover from the initial debacle with a series of optimizations that have created the first GeForce GTX 460 and GeForce GT 580, 570 and 560 you then.

GeForce GTX 550 you up close

For the test we have today received a card from Zotac provided, one of the most important partners of NVIDIA in the Italian market. The solution, which belongs to the family AMP!, Features a factory overclock: the GPU is in fact set to 1 GHz compared to the default of 900MHz and memory at 4400MHz 4104MHz against the standard. We are faced with a tab marked, even in this case, by a system of heat dissipation double slot. View and considered that this band is dedicated not exclude that in the weeks to come, may be proposed solutions cooled by a single-slot cooler, maybe with standard operating frequencies. In this case the fan, located in the center of the solution, air conveys the heat sink which deals with heat to cool the GPU. Unlike the proposals for the high end of the market does not create a flow of cooler air that is expelled through the grid of the retention bracket. four connections are provided by the solution provided by Zotac, but only two are used simultaneously. In addition to the canonical DVI card is also equipped with an HDMI and a DisplayPort: the latter two versions are not "mini" and therefore do not require an adapter to be connected to any monitor . The grid occupies part of the upper zone of the mounting bracket: as we have seen the fan creates an air stream that blows out the design of the cooling system chosen by Zotac. The sink which was developed Zotac solution is extremely simple: only fixed by four screws to the PCB is composed of a central block built of aluminum, surmounted by a fan. The latter component, blowing air directly on the radiator Reed, cools the GPU during its operation. The layout of the board, after removing the heatsink, it is very simple and essential: the rear of the PCB is occupied by the capacitors and power circuitry. The GPU is instead surrounded da cinque moduli di memoria. Tra le novità introdotte in GeForce GTX 550 Ti, una delle più evidenti è il bus di memoria portato da 128 a 192 bit di ampiezza. Questo elemento gioca un ruolo fondamentale per l'incremento prestazionale, garantendo infatti un aumento diretto della bandwidth di memoria. La presenza di un bus di 192-bit implicherebbe l'utilizzo di un quantitativo di memoria di 768 Mbytes o 1,5 Gbytes, a seconda della densità dei moduli memoria utilizzati: sino ad oggi infatti, tutti i produttori si sono sempre dedicati allo sviluppo di soluzioni con moduli di memoria di equivalente densità. Lo schema a seguire mostra come il frame buffer sia stato interfacciato alla GPU: In GeForce GTX 550 Ti found for the first time, a memory controller capable of supporting modules to mixed density: in this way NVIDIA has managed to keep the cost of production compared to any card with 1.5 Gbytes of memory and at the same time, ensure greater buffer with 768 Mbytes compared with the proposals.

The test platform

To analyze the performance of graphics cards in a test we used a processor-based platform Intel Core i7 975 Extreme with the default clock frequency of 3.33 GHz to 3.73 GHz range via increase in the frequency multiplier. Turbo Boost technology has been disabled, making it possible that the CPU clock frequency is always fixed on the 3.73 GHz pre-set bios. The following are details of the components used in the tests: Processor: Intel Core i7 975 Extreme, clock speed increased to 3.73 GHz via increased frequency multiplier up to 28x; memory RAM: 3x2 Gbytes Corsair TR3X6G1600C8D; clock frequency 1600 MHz with timings of 9-9-9-20 at 1T; Hard disk: Western Digital WD7500AAKS, 750 Gbytes SATA 7200 rpm; Motherboard: MSI Eclipse SLI X58 Intel chipset; System OS: Windows 7 Ultimate 64bit, with all the latest fixes issued by Microsoft; NVIDIA Drivers: Forceware 266.66 - 266.58 AMD Video Drivers: Catayst 11.1 - 11.2_cap3; Supply: Topower 1100 Watt. The following video cards used in the review: NVIDIA GeForce GTX 560 Ti: 822 MHz GPU clock, 384 stream processors@1.644 MHz, 1024 MHz GDDR5@4.008 Mbytes memory on a 256bit bus NVIDIA GeForce GTX 460 : 675 MHz GPU clock; Processors@1.350 stream 336 MHz, 1024 MHz GDDR5@3.600 Mbytes memory on a 256bit bus NVIDIA GeForce GTS 450 : 738 MHz GPU clock, 192 stream processors@1.566 MHz, 1024 MHz GDDR5@3.600 Mbytes memory on a 128bit bus NVIDIA GeForce GTX 550 Ti: 900 MHz GPU clock, 192 stream processors@1.800 MHz, 1024 MHz GDDR5@4.104 Mbytes memory on a 192bit bus Zotac GeForce GTX 550 Amp you! : 1000 MHz GPU clock, 192 stream processors@2.000 MHz, 1024 MHz GDDR5@4.400 Mbytes memory on a 192bit bus AMD Radeon HD 6950 : 800 MHz GPU clock, 1408 stream processors @ 800 MHz, 2 Gbyte memory GDDR5@5.000 MHz Bus 256bit AMD Radeon HD 6950 : 800 MHz GPU clock, 1408 stream processors @ 800 MHz, 1 Gbyte memory GDDR5@5.000 MHz Bus 256bit AMD Radeon HD 6870 : 900 MHz GPU clock, 1120 stream processors @ 900 MHz, 1 Gbyte memory GDDR5@4.200 MHz Bus 256bit AMD Radeon HD 5770 : 850 MHz GPU clock, 800 stream processors @ 850 MHz, 1 Gbyte memory GDDR5 @ 4800 MHz Bus 128bit These titles included in this comparison, with the different configurations used: Far Cry 2 Tests performed with settings on very high quality, for all the items, using the DirectX 10 API, with anti aliasing 4x and 8x. HAWX Tom Clancy's 2 Benchmark integrated into the game, used in the demo version, performed by selecting all the quality settings on high. The tests were performed with DirectX 10.1 with 4x and 8x anti-aliasing enabled. Just Cause 2 We used the benchmark built into chaos demo version in the game, selecting 4x anti-aliasing, 16x anisotropic filtering. The quality settings selected were all brought up high, with the exception of SSAO has been disabled. Mafia 2 This title has been used the demo version, selecting the benchmark integrated with higher quality graphics. Anti aliasing is not working properly and for this reason has been disabled. Alien Vs Predator The benchmark that uses the engine of this game was made by selecting for setting high quality of texture and shadows, 16x anisotropic filtering, anti aliasing 2x and 4x anti-aliasing, tessellation enabled, advanced shadow sampling SSAO and disabled; DirectX 11 API. Metro 2033 E 'was used benchmark integrated, enabling the DX11 API, all quality settings on high level, and 4x anti-aliasing off, anis 16x and DOF off. F1 2010 The popular and recent driving simulator was performed impostanto all configuration parameters to the highest quality, enabling 4x anti-aliasing filters graphs were generated by sorting the results from highest to lowest, taking as reference the resolution of 1680x1050 pixels unless otherwise specified. The limited number of cards inserted is related to two reasons: first, a simple choice to make the wording more clear and understandable as possible the comparison, the second related instead to changes made to the test platform and settings of the benchmark run. In the list of missing Radeon cards HD 6850, la fascia media di AMD: in occasione dei test la scheda non era disponibile, ma la recupereremo quanto prima per aggiornare la nostra analisi. Nei grafici sono presenti risultati prestazionali della scheda GeForce GTX 550 Ti sia con impostazioni di default sia con le frequenze overcloccate della scheda Zotac GeForce 550 Ti AMP!. Far Cry 2 e Metro 2033 GeForce GTX 550 Ti si colloca sulla parte bassa del grafico prestazionale: la soluzione nasce infatti come erede naturale di GeForce GTS 450 ed è destinata alla fascia mainstream del mercato. Il confronto con la proposta della concorrenza, ATI Radeon HD 5770, mette in evidenza una sostanziale superiorità della nuova proposta di NVIDIA. Solo in Metro 2033 con filtro anti-aliasing 4x Radeon HD 5770 riesce a stare davanti alla proposta GeForce GTX 550 Ti standard. Alien vs Predator e HawX 2 Due dei tre titoli presi in considerazione in questa pagina mettono in evidenza come la "datata" Radeon HD 5770 sia ancora in grado di garantire un livello prestazionale particolarmente interessante, capace di far registrare valori di tutto respect. The solution of AMD's mainstream is thus able to be on top, measuring range, the new GeForce GTX 550 you reference, but not the version proposed by overclocked Zotac. HAWX 2 shows that like the high operating frequencies that characterize GeForce GTX 550 Ti and it is no coincidence that anti-aliasing set to 4x overclocked the solution is able to registrar values \u200b\u200beven higher than the Radeon 6870 HD resolutions of 1680x1050 pixels and 1280x1024 pixels. By shifting the anti-aliasing to a factor of 8x, the 192 shader GeForce GTX 550 you emerge as a limit and the card has stabilized at the bottom of the chart performance. Just Cause 2, Mafia 2 and 2010 F1 the last two graphs considered confirm the trend seen so far: GeForce GTX 550 I was able to director a marked increase in performance compared to the model hence, GeForce GTS 450 and it also shows generally higher Radeon HD 5770. The difference in terms of fps that the proposal allows to register Zotac graphics card with respect to the frequency of operation is in default and it is quite evident. As we will highlight the increased frequency has no major side effects on operating temperatures and consumption: change from 900MHz to 1GHz is therefore particularly advantageous. consumption, noise and operating temperatures The noise of the cards was detected using a sound level meter, set in dbA reading and Fast, with recognition at a distance of 5 cm from the card installed in a system outside of the case. The reading is at idle with no desktop and 3D application running, the full load was detected while running the benchmark of the HAWX game at a resolution of 2560x1600 pixels. Noise levels that solution intended for mid-market NVIDIA is able to ensure rimangon are particularly low and well below the threshold of concern. Despite the high frequency of operation, the sink can always operate below 50 dB, with a delta of changes between scenario with minimum stress and the card with graphics card in idle. We analyzed the power consumption of the entire system with upstream Wattsup Pro tool, to provide a real scenario as far as possible we have preferred to avoid running in a loop test as sitentici FurMark, opting to run di una sessione di Far Cry 2 alla risoluzione di 2560x1600 riportando il valore di picco. La misurazione dei consumi mette in evidenza come GeForce GTX 550 Ti, in idle, faccia registrare l'assorbimento a monte del sistema minore dell'intero lotto di schede considerate. Per offrire uno scenario quanto più possibile completo abbiamo testato la scheda sia con frequenze di funzionamento standard, sia overcloccata. Sempre osservando il grafico relativo alla sessione in idle è possibile notare come nel range di 10 Watt si trovi quasi le metà delle schede prese in considerazione: le importanti migliorie portate avanti negli ultimi anni hanno permesso di ridurre in modo sensibile l'assorbimento delle graphics cards, including high-end, when not in use. The very high operating frequencies can be felt with the collection of consumption during the stress scenario Platform: GeForce GTX 550 Ti salt at the same level of consumption of Radeon HD 6870 and goes far beyond what was recorded GeForce GTS 450, solution with the same number of stream processors but characterized by much smaller operating frequencies. detection of operating temperatures of the GPU was done in two different ways. The first includes the performance of three benchmark scenes in sequence with Far Cry 2, the resolution of 1920x1200 pixels with 4x anti aliasing, monitoring the temperature attraverso il tool GPU-Z. Le temperature rilevate durante l'esecuzione di Far Cry 2 in loop posizionano GeForce GTX 550 Ti al di sopra di Radeon HD 5770 e GeForce GTS 450. La differenza tra la versione overcloccata e quella standard è minima ma sussiste: in entrambi i casi la temperatura rimane vicina ai 75° di picco, ben al di sotto quindi della soglia di attenzione. La seconda invece prevede l'esecuzione in loop di Furmark con ventola di raffreddamento portata alla massima velocità di rotazione. Portando la ventola al massimo ed eseguendo Furmark le due soluzioni GeForce GTX 550 Ti (versione standard e overcloccata) si assestano attorno 70 °, we are about ten degrees above the temperature of the Radeon HD 5770. The very high operating frequencies lead to a direct rise in temperatures that remain, even in this case, below the threshold of concern. Conclusions The Ides of March has always been for the Roman people, a good omen. NVIDIA launches GeForce GTX 550 you own March 15, replacing GeForce GTS 450: the new born will be used to market the high volumes and will posizionari as a proposal for those entry-level che volessero aggiornare il proprio sistema e dotarsi di una scheda grafica che consenta di giocare in modo fluido ai titoli di ultima generazione. L'approccio proposto da NVIDIA con GeForce GTX 550 Ti è lo stesso che è stato portato avanti con la serie GTX 500: una ottimizzazione a livello di transistor che ha consentito di andare a migliorare in modo significativo l'efficienza della GPU. Questa ottimizzazione ha così consentito di andare anche ad incrementare la frequenza di funzionamento: la nuova nata di casa NVIDIA è infatti quasi 120MHz più veloce del modello precedente, GeForce GTS 450. Per la commercializzazione del nuovo modello, anche in questo caso, NVIDIA si appoggia ad una strategia già messa in pratica that has got to prove successful: it will be left ample room for partners who will now have the ability to market since the day of the introduction of its new model customized solutions. This is the case you Zotac GTX 550 Amp! which comes to us in writing during the test and we downcloccato to simulate the reference card. The level of overclocking the card is able to ensure, as evidenced by the solution proven in these pages, is remarkable and does not involve particular problems: GeForce GTX 550 you can easily reach 1 GHz without the need for solutions raffreddamentoparticolari. The advantages in terms of frames the second with the games are sensitive and allow you to go to improve, even if not revolutionize, the performance of the card. During the days after launch we will observe the traditional and usual sequence of announcements by companies partner of NVIDIA: do not rule out that through the use of a particular sink, perhaps with a vapor chamber technology, it is possible to life to a single slot solution. This would be particularly attractive in our view, in particular for use in systems with a smaller size. recommended retail price for NVIDIA GeForce GTX 550 Ti is 139 € including VAT: This is the official price But that could not be applied by all partners. Zotac's solution considered in this article, GeForce GTX 550 Amp you!, Will be sold at a price of 159 €. The price puts the tab above livemente Radeon HD 5770, currently stable at € 115-120: the costs may still close in the coming weeks, with the slow and gradual decline in the price of NVIDIA. Summing up the new born at home NVIDIA is an interesting proposal for all those who have the need to upgrade your system but do not have a budget to spend important: if you do not want to play at a higher resolution than of 1920x1200, without exceeding the anti aliasing, the GeForce GTX 550 you can tell her. source : hardware upgrade
