2012 was the opportunity to discover many graphics cards and performance soared. History does not change because AMD and Nvidia parties seem to start a new Hundred Years War. The profit goes directly to the players who benefit from prices still falling but also new more efficient models.

 

The two main actors in the video card market took this year to introduce their new range of GPUs and it has discovered many versions. This does not really help users often embedded in Dell Inspiron 1545 product lines extremely rich and varied. The factory overclocked versions have become common and cooling systems owners replace the reference coolers so much the better! It thus gains in efficiency and especially noise. AMD has unveiled its next family "Southern Island" composed GPU 7900, 7800 and 7700. Nvidia has called his "Kepler" with reference GTX 680, 670, 660 and 650.

 

Different flavors are invading this catalog. Nvidia adds cards stamped "Ti" a little more swift than the version original and AMD goes much further with each chip models 50/70 (eg 7970 and 7950) without forgetting the references say "Gigahertz Edition" and even " Turbo Edition ". So what graphics cards are the most interesting in terms of XPS M1330 performance? In terms of prices? What are the strengths and weaknesses of the proposed maps?

 

Eighteen cards from seven manufacturers allow us to choose the perfect graphics card.

 

The AMD & Nvidia GPU

 

AMD

Start with the most important  Dell E4310 Battery brand in number. We are dealing with the Southern Island family in which share three different graphics chips engraved in 28 nanometers all (called Graphics Core Next), supporting the following technologies:

 

PCI Express 3.0

DirectX 11.1

Eyefinity (multi-screen)

AMD App Acceleration (hardware decoding of video playback), HD3D (3D games)

PowerTune (dynamic TDP)

ZeroCore Power management (power consumption)

 

Tahiti: Gigahertz HD 7970 Edition, HD 7970 and HD 7950

They boarded more than four billion transistors for 32 ROPS. Based on the memory bus 384 bits. The number of different calculation units. He spends the HD 2048 for 7970-1792 for the HD 7950. CPU frequency also changes: 1000 MHz for the HD 7970, 925 MHz for the standard version and finally 800 MHz for the HD 7950. Memory: Everyone in the same boat with 3 GB GDDR 5 and as for the GPU, the RAM that varies for the HD 7950 clocked at 1250 MHz against 1375 for the HD 7970.

 

Pitcairn: HD 7870 and HD 7850

 

The first version of the high-end AMD called Pitcairn. This is the same architecture as the HD 7970/50 but with much less transistors because we "limit" by 2.8 billion. Are concerned the HD 7870 and HD 7850. The number of ROPS is still 32 but the number of computing units is lowered with the HD 1280 for 7870 and 1024 for the HD 7850. Memory loses 33% capacity which will have little impact on the HD resolutions (1920x1080 pixels). Beyond the configurations or multi screens, this factor will be taken into account depending on the games used. We therefore turn to 2 GB this time on a 256-bit bus. The  HP G42 Battery frequency is in favor of the HD 7850 clocked at 1250 MHz. The HD 7870 is merely 1200 MHz. An imperceptible difference in practice.

 

Cape Verde: HD 7770 and HD 7750 Ed GHz

The entry level AMD is also in two models with 1.5 billion transistors and the number of ROPS is divided by two for a total of 16.

640 units of computation are present in the HD version in 7770 and 512 HD 7750.

Memory 1 GB falls to a lower frequency to the detriment of the HD 7750 clocked at 1125 MHz. That of the HD 7770 wins 25 MHz to 1150 MHz. Again a difference not noticeable in practice. These entry-level cards are not designed for high resolutions, memory capacity does not limit performance.

 

Nvidia

 

Nvidia, things are simpler with five categories but only three processors: the GK104 more efficient than the GK 106. There is the GK 107 on the lowest card (GTX 650) excludes from our comparative performance too limited. We can already inflict gold and a red card to the brand that has misled players not because GTX 600 is not fully compatible with  HP G4 Battery DirectX 11.1, contrary to what has been said. Some features (admittedly minor) are not supported. However, this time against little tarnish at all these great GTX GPU are 680, 670, 660 Ti, 660, 650 and 650 Ti.

 

The novelty of this family "Kepler" is the appearance of the controversial technology "GPU Boost" because if it achieves higher frequencies as the CPU Turbo mode, it is likely to vary between two identical cards sold in commerce. Wildfire or not, we feel at 59Hardware we did not really cry foul if the neighbor who bought the same car you are going 10 km / h faster ...

 

Another novelty of Kepler, we have the right to two new HP G6 Battery modes called anti-aliasing filtering and FXAA TXAA. "Adaptive V-Sync" limit the effects of stuttering and slowdowns. 3D Vision can wear new glasses are not reimbursed by social security and Nvidia Surround supports up to four monitors. So there is something for everyone but especially all budgets.

 

GTX 680 and GTX 670

 

At the top of the charts, the GTX 680 and GTX 670 ship 3.54 billion transistors but only the 1536 GTX 680 sailed computing units and GTX 670, 1344 (GTX 660 Ti like). They are the only ones to benefit from 32 ROPS. Frequency side, the GTX 680 is the only one to surpass the gigahertz with 1006 MHz. The GTX 670 is to accommodate 915 MHz (another common point with the GTX 660 Ti). Both processors are coupled with 2GB of RAM based on a 256-bit bus and clocked at 1502 MHz. The performance range is occupied by the GTX 660 and GTX 660 Ti features and mix pell-mell with the GTX 670 Ti 650 and GTX.

 

GTX 660 and GTX 660 Ti

 

The GTX 660 Ti offers the 3.54 billion transistors of the GTX 670 and 1344 processing units clocked at 915 MHz. For cons, the number of ROPS down to 24 as the memory bus which passes always 192 bits for a capacity of 2 GB 1502 MHz clocked at. The GTX 660 loses transistors path to reach 2.54 billion (just like the GTX 650 Ti) and therefore the number of calculation units 960 passes while the frequency back to 980 MHz. 2 GB of RAM are always on a 192-bit bus and its frequency does not change with either 1502 MHz.
