Today we take a look at the new G92 version of the GeForce 8800 GTS graphics card from Nvidia featuring 512MB of onboard memory and a suggested retail value of around $350 US. This new 512MB version is designed to replace the existing 320/640MB 8800 GTS graphics cards, offering better performance at the same price point. But how will this new graphics card fair against the existing 8800 GT and GTX competition, not to mention the Radeon HD 3870!
Rather than just give us the GeForce 9 series that we are all eagerly awaiting, Nvidia has given us two new GeForce 8800 graphics cards for Christmas. First we were presented with the GeForce 8800 GT, which seemed like a bit of a godsend at the time. The 8800 GT was released roughly 2 months ago now and still these cards can be difficult to come by, while we are yet to see them go for the MSRP (Manufacturer Suggested Retail Price). The MSRP for the 8800 GT was $200 US for the 256MB version and $250 for the 512MB version, though most of the large online retailers are selling them for $270 US or more, with the biggest problem being that most large online retailers do not have stock!
So therefore picking up a GeForce 8800 GT graphics card before Christmas and at the right price, is going to be very difficult. For this reason many are turning to the new Radeon 3870 and Radeon 3850 graphics cards, though so far availability on these products has not been great either. Today Nvidia will be releasing another new “affordable” performance graphics card, as they re-launch the GeForce 8800 GTS. This new version of the GeForce 8800 GTS is based on the G92 architecture, meaning that it is built using a 65nm design process and will come stocked in 512MB and potentially 1024MB versions.
Currently there are already two versions of the GeForce 8800 GTS supporting 320MB and 640MB of onboard memory. The 320MB version, which is of course the cheaper of the two, costs roughly $300 US while the 640MB version can be had for just $50 US more, at the moment. The MSRP for the new 512MB version of the GeForce 8800 GTS is said to be between $300 and $350 US, meaning it should cost about the same as the existing 640MB version which it is designed to replace. Although this newer version does loose 128MB of local memory, it is actually a far more impressive product in terms of specifications, even when compared to the GeForce 8800 GT.
The GeForce 8800 GT for example features 112 SPUs clocked at 1500MHz, while there are 56 TAUs (Texture Address Units), along with 16 ROPs (Rasterization Operator Units). The 8800 GTS 512 on the other hand boasts 128 SPUs, which is the same amount as the GTX and Ultra, though they are clocked higher at 1625MHz. The 8800 GTS 512 also features 64 TAUs and 24 ROPs. Then to finish the 8800 GTS 512 off nicely, Nvidia has given this new graphics card a 650MHz core speed, along with 1940MHz GDDR3 memory! The only weakness we see in the 8800 GTS 512’s armour is the 256-bit wide memory bus, which was also used by the GeForce 8800 GT.
Previous versions of the GeForce 8800 GTS (320MB/640MB) have used a 320-bit wide memory bus, where as the 8800 GTX/Ultra cards use a 384-bit bus. This has limited the memory bandwidth of the GeForce 8800 GTS 512 to 62.7GB/s, which is slightly more than that of the 8800 GT, but slightly less than that of previous 8800 GTS graphics cards. So it will be interesting to see how this new GeForce 8800 product performs, as it should smoke the GeForce 8800 GT given its specifications.
On paper it has a few weaknesses when compared to the existing 8800 GTS graphics cards, but the 8800 GT was able to wipe the floor with them, so realistically the 8800 GTS 512 should be faster than the 8800 GTS 320/640MB versions as well. Given how close the GeForce 8800 GT already is to the GTX in many of the games we test with, it shall be interesting to see where the 8800 GTS 512MB stands in this now crowded GeForce 8800 family. Before we move on to check out the performance, let’s just take a few moments to look at the early production card that has been supplied to us by ASUS...
