I assume we will see them rivalling the red teams cards except for bit allign. RE: keplar predictions - atom - 03-17-2012 You can calculate this very simple. NOTE: This is -very- inaccurate The gtx570 (overclocked to 1600Mhz) makes 2170.5 Mhash/s on MD5. It has 480 SP. 480 x 1600 = 768000 2170500000 / 768000 = 2826 The gtx680 has 1536 SP and 1006Mhz = 1545216 1545216 * 2826 = 4366.7 Mhash/s (The hd7970 makes 8213.6 Mhash/s on MD5) RE: keplar predictions - blazer - 03-17-2012 atom Wrote:NOTE: This is -very- inaccurate LOL i like that atom, i guess its an improvement for nvidia. Time will tell. Looking forward to some benches on a keplar card with hashcat soon. RE: keplar predictions - Rolf - 03-18-2012 If some asian sources prove to be correct, GTX 680's shader domain will be clocked at 1.411Ghz(stock), which will boost MD5 speed to 6.124B p/s. Hopefully they are correct! RE: keplar predictions - blazer - 03-18-2012 relevant RE: keplar predictions - atom - 03-18-2012 ForceWare 300.99... RE: keplar predictions - atom - 03-20-2012 Its still unclear if gtx680 has BFI_INT and / or BIT_ALIGN instruction. This would boost speed by ~ 40%. RE: keplar predictions - blazer - 03-21-2012 Not sure how reliable src(here) Quote:nv680compute Wow! The claim of beating the HD7970 goes right into the thin air, it seems. Nvidia's new GPU is beaten by the Radeon HD 7970 by an order of magnitude here in double precision floating-point, as well as nearly twice in ordinary single precision floating point. One is speechless here. Even the Radeon HD 7870 with its restricted double precision floating-point still outperforms the GTX680 by a noticeable margin in this department, as you can see here. Only the Radeon HD 7850 is substantially slower. Looks like RED: 1 Green: 0 RE: kepler predictions - Rolf - 03-23-2012 Ok, disappointment number 1: shader clock is no more, shaders run at core clock. Disappointment number 2 (mot confirmed): like FP64 and FP32, integer performance will be 1/2 or 1/4 int ops per shader. That will mean, if the worst case scenario happens, GTX 580 will be faster than GTX 680. However, since no reviewers use oclhc-plus or other hashcracking apps, someone has to do it manually.
