GeForce 8600 and 8500 unified shader amounts unveiled

DailyTech has come across more details of NVIDIA’s upcoming GeForce 8600 GTS, 8600 GT and 8500 GT graphics processors. NVIDIA expects to unleash the GeForce 8600 and 8500-series graphics processors later this month. AMD is ready to take on NVIDIA’s midrange offerings with its upcoming ATI Radeon HD2600 and 2400 offerings.

Slotting below NVIDIA’s GeForce 8800 GTS 320MB SKU is the GeForce 8600 GTS. The top end G86-based graphics processor features 32-stream processors clocked at 1.45 GHz. NVIDIA pairs the 32-stream processors with 256MB of GDDR3 memory clocked at 1.0 GHz. A 128-bit memory interface connects the memory to the GPU for 32GB/sec of memory bandwidth.

Sporting lower clock speeds is the GeForce 8600 GT. The GeForce 8600 GT has the same 32-stream processors as the GTS; however, the unified shaders have a 1.18 GHz clock. Core and memory clock are also lower at 540 MHz and 700 MHz, respectively. Memory bandwidth is downgraded to 22.4 GB/sec as a result of the lower memory clocks.

Filling in the bottom of the retail GeForce 8-series lineup is the GeForce 8500 GT. The value model has 16-stream processors clocked at 900 MHz – half the amount present on the GeForce 8600-series. NVIDIA pairs the 450 MHz core with DDR2 memory clocked at 400 MHz. The GeForce 8500 GT features the same 128-bit memory interface as the GeForce 8600-series. Memory bandwidth is downgraded to 12.8 GB/sec.

Expect NVIDIA to launch its new midrange product lineup tomorrow.  Additional details are already starting to leak out early, and some brick-and-mortar stores already have the cards on the shelf.

How well do these stream processors scale? Do three times as many stream processors result in three times the performance?

I seem to recall seeing some preliminary benches (can't find the link anymore) that showed 8600 GT (possibly GTS) slightly outperforming a 7900 GS. The question thus is: what's the price, and is DX10 performance remotely acceptable? It's a midrange card, but if it costs about $150 that's still good enough for a lot of people. Turn off AA, run at 1680x1050 or less, and you're probably set for a while.
