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.

8600 GTS

Compared to the 8800 GTS' 96 stream processors doesn't 32 see like a bit of a ripoff at the 8600 GTS' price point?

True, but these mid-range cards aren't power sucking monsters that take up more space than what some mini towers have room for.

About the ONLY mini-tower PC the 8800 and other dual-slot-area cards that don't fit into are the Dell minis. Currently models e520/e521.... because of the stupid BTX design (Apparently, Dell is the ONLY BTX manufacture on the market, but at least its industry standard heheh).

8800GTX will fit in the older silver HPs and the new shiny-black HPs - which don't be fooled, they only flipped the motherboard. The CPU is at the bottom, slots are on top. The card will fit just above the Hard Drive bays.

Of course the PSU has to be replaced ;)

8800GTX doesn't fit in Antec Sonata I/II and other mid-tower cases where the HDD cage blocks the longer VGA card.

It is a ripoff, the 6600 was basically half of the 6800.
Same with the 7600, half the rops/pipes as the 7800.
Now this 8600 has a 1/4 of stream processors of the 8800, it should also cost a 1/4 of the price if you ask me.
I hope ati comes out with something better in the midrange then what nvidia.

96 / 32 = 3


Also, keep in mind that the GPU is only part of the cost of a video card. All of that high-speed RAM costs money too, as does the PCB, heatsink, etc.

Obviously they mean 1/4 of the high-end.

Oops! I looked at the GTS numbers and thought they were for GTX.

Not really quite a rip.

The 6600s were about half the price of the 6800s.
And When I paid $175 for my 7600GT ($25 extra for the Gigabyte heatpipe version) the 7900GT was a $300~350 card.

The sub $200 ($150~175) is the sweet spot. If they provide good performance at that price. ATI lost market share because there mid-range cards were $50~75 too expensive.

But looking at the pricing:

$280 = 8800GTS 320 (They should have called it the "GT")
$400 = 8800GTS 640 (a bit faster)
$550 = 8800GTX 768

If the 8600GTX can equal a 7950GT for $200, it would be a fair price... but we'll see in a day or so.

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.
