NVIDIA today launches its newest mainstream part, the GeForce 8800 GT

NVIDIA today is set to launch its newest midrange graphics card part, the GeForce 8800 GT, previously known by its codename G92. NVIDIA guidance states that its newest graphics card will be sold at a retail price in the $199 and $249 price range.

Development around the G92 processor revolved around reducing the thermal and power draw on the GeForce 8800 GTX (G80) processor.  G80 was manufactured on TSMC's 90nm process node while the G92 is manufactured on TSMC's 65nm node.  This shrink allows a single 8800 GT to operate on a 105 Watt draw, almost 80 Watts less than the 8800 GTX during heavy operation.

Top-to-bottom, the GeForce 8800 GT fits snugly between NVIDIA's GeForce 8800 GTS 640 MB, which NVIDIA sets at a retail price of $349, and NVIDIA's GeForce 8600 GTS, which is sold for $149.

The GeForce 8800 GT sports a 100 MHz speed bump over the 8800 GTS, and comes factory clocked at 600 MHz. The 600 MHz clock speed of the 8800 GT is actually 25 MHz higher than the 8800 GTX's default GPU clock, which is set at 575 MHz. The 8800 GT's clock speed also comes within striking distance of the GeForce 8800 Ultra's 612 MHz GPU clock speed.

The NVIDIA GeForce 8800 GT features 112 stream processors, 16 fewer than the 128 stream processors found on the ultra high-end 8800 GTX and 16 more than the 96 stream processors found on NVIDIA's 8800 GTS.

The stream processors of the 8800 GT come clocked at 1500 MHz, the same speed as the stream processors of the GeForce 8800 Ultra. Comparatively, the GeForce 8800 GTX comes with its stream processors clocked at 1350 MHz while the 8800 GTS' stream processors are clocked at 1200 MHz.   

The GeForce 8800 GT features up to 1024MB of GDDR3 memory, which is based on a 256-bit memory interface. According to NVIDIA, total memory bandwidth rings in at 57.6 GBps, and the texture fill rate is 33.6 billion/second. Naturally, the two preceding figures are only theoretical values; actual values are bound to be quite different.

The GDDR3 memory of the GeForce 8800 GT comes clocked at 900 MHz -- equal to the memory frequency of the GeForce 8800 GTX. However, the 8800 GT falls short of the 8800 Ultra's memory speed, which is 1080 MHz (2160 MHz effective).

NVIDIA guidance states that the GeForce 8800 GT supports the new PCIe 2.0 bus standard. The PCI-Express Special Interest Group claims that the new bus standard yield improvements in bandwidth.

High-definition video fans will be glad to hear that the GeForce 8800 GT comes integrated with support for NVIDIA's 2nd generation PureVideo HD engine, which allows for H.264 video decoding to be offloaded from the processor and on to the video card.  HDCP support is also present on all reference designs.

NVIDIA guidance promises a hard launch with its GeForce 8800 GT cards, however, so far only Gigabyte, Palit and Zotac have 8800 GT-based offerings.  Newegg independently confirmed with DailyTech that the card will be available online after the 6AM embargo lift.

Practical SLi At Last?

Strictly looking at price point at the moment, and only at the nVidia Line-Up:

- DailyTech claims: $200-$250 Price Range for an 8800GT.
- Average Price of an 8800GTX is $500 (give or take, pricing from NewEgg).
- Average Price of an 8800GTS 640MB is $360 (NewEgg).

If you have an SLi enabled motherboard, you could pickup two 8800 GT's for around $500. This would give you 1024MB of memory versus the GTX's 768MB. Now the GTX does have faster clocked memory, true, but if you purchase a PCI-e 2.0 board would you not be getting a bandwidth advantage to help offset this difference in memory clock speed?

The article claims that a 1024MB version of the GT may also appear which lends even more support to a "practical" SLi setup. When I mean practical, I mean price point. I would rather pickup two GT's for $500 than two GTX's or 640MB GTS's which would break the $1000 mark. In my opinion $500 is a fairly acceptable sum for an SLi setup and I am really hoping to do just that when these cards become more readily available, the ZOTAC 8800 GT really looks like a beast and the benchmarks that users have posted speak for themselves: It's not the most powerful card out there, it's not meant to be, but it will definitely give you an awesome gaming experience without breaking the bank. I am very curious to see the kind of pressure this card will put on ATI and the OEM market.

With SLI you cannot simply add the amount of RAM, it's still 512MB on each card that counts. Therefore at ultra-high resolutions you will probably run out of memory sooner than with a GTS 640 or a GTX (both solo or SLI).

I am not so sure about 1024MB versions of the GT. It would not make sense to do that with a "bargain" card, unless soon the older models GTS, GTX and Ultra become completely obsolete. Even then it would be smarter to slap 1 Gig on the top model, but right now there does not seem to be the need for that (look at the AMD 1GB: virtually no difference)

From the looks of the benchmarks the 512MB are not holding the GT back, but you can see that 256bit instead of 320 bit interface takes its toll, albeit not too badly. 1 Gig GTs would be like those 6600GS or 7600GS with 512MB - superfluous or even idiotic because the RAM is probably cheaper and slower.
