(new set of) Nvidia G80 specs leaked?
NVIDIA G80 specifications leaked?
05-Oct-2006, 17:35.29 Reporter : Uttar DailyTech has leaked apparently reliable specifications for NVIDIA's upcoming G80. They claim it will be hard launched in the second week of November and that the initial line up consists of the GeForce 8800GTX and the GeForce 8800GTS. Both cards are apparently based on an unified design, with the full chip consisting of 128 "stream processors", while the GTS will have only 96 enabled for yield reasons. The information further confirms other tidbits originally revealed by some this made the front page of beyond3d.com http://beyond3d.com/#news34328 __________________________________________________ _______________________ NVIDIA G80 specifications leaked? 05-Oct-2006, 17:35.29 Reporter : Uttar leaked chinese powerpoint slides, including a 384-bit memory bus for the GTX and a 320-bit memory bus for the GTS, with 768 and 640MB of video memory for the two SKUs. The specifications also claim that the unified stream processors are clocked at 1.35GHz for the GTX and 1.2GHz for the GTS, while the control logic, schedulers, ROPs, etc. are clocked at 575MHz and 500MHz for the GTX and the GTS, respectively. Other DailyTech news pieces published today reveal power requirements of 400W to 450W for a G80-based system, and 800W for one based on SLI G80s. As always, these numbers tend to be highly exaggerated in order to reduce potential problems with subpar OEM PSUs. Other related articles claim FP32 HDR and 16x AA support, both of which have been hinted at in the past, and the former actually being a requirement for D3D10. To be more precise, FP32 blending is a requirement, while FP32 filtering is optional. A fourth article on the site also speaks of NVIDIA's "Quantum Physics" engine, which is most likely a marketing name for the better acceleration G80 delivers to physics computations. It should also be noted that DailyTech lists some rather unlikely numbers in terms of memory clocks and texture rate. They list the GTX as having 86GB/s of bandwidth, and the GTS only 64GB/s. However, they also claim both have 900MHz GDDR3, which is highly unlikely. It should be relatively clear that this was a simple typo, and that the GTS actually sports 800MHz GDDR3. As for texture rates, they give the number of 38.4GPixels/s for the GTX, but few logical ways exist to attain such a number with the specified clockrates. As such, it seems much more likely that this part of the specification relates to the GeForce 8800GTS and its 1200MHz stream processors. __________________________________________________ ________________________ |

Do you know if it's DX 10 capable?

I'm waiting for an SM 4.0 capable laptop, but given how much heat this thing is putting out, it looks like its going to be a while. I wonder how noisy that sucker will be considering the two external power connectors on the board!? Can't leave computers on these days if not using them - wife is complaining about the noise! Nice energy saving trick, good job NV and ATI. |
