Yeah, well, yes... tomshardware has to make money too, they have one link like that in every article (one only, kind of random, the rest of the links in each article are "normal"). His bad luck was that it happened to be exactly in the fragment he quoted, and he copy/pasted with link, is easy to miss, especially if your browser doesn't color/mark/underline, etc, the links. No harm done.

Makes it almost pointless to run my 1070s.

They're still 37% faster than my RX 480 at the same TDP.

I thought you were just bringing the kit back online to heat your space using electricity during the winter?

Multiple options... Crypto (mostly a fool's game). Primes. Factors. Etc et al. Your kit; your time; your electrons. Your choice.

Work with what you are given. Please forgive me if I'm telling you how to chew gum... 9^)

Thanks for any and all cycles. Where ever you decide to send them. 8-)

Crypto paid for them. Broke even. I should have mined more. Only four running at the moment. I should have more hardware coming online soon.

I've got cheap electricity rates locked in for the next 22 months. Same with gas, though heating with computers is more fun. Going to see if I can break 2 MWh/month for giggles.

I'm looking at TFing the 518 exponents at 76 bits in 96M and 97M to 77 bits. It looks a bunch more above there should be TFed higher as well. Would be nice to eliminate more DC work to speed that project along.

Sounds excessive to me; GTX 1070 are 1:32 SP/DP so 76 bits is enough.

https://www.mersenne.ca/exponent/96095581 shows a 4 bit differential, 71 for CPU, 75 bits for GPUs.

Giggles is a worthy goal. 9-)

And... Depending on where you are currently located, if you can heat your human space(s) using renewable electricity rather than burning gas, that's a net plus for the whole enthalpy/entropy thing... 8-)

not surprisingly

According to the specification sheet, the GeForce RTX 4070 Ti uses the AD104 (Ada Lovelace) silicon, the same die at the heart of the GeForce RTX 4080 12GB. The die, which measures 295 mm², houses up to 7,680 CUDA cores. Although Colorful didn't confirm the number of CUDA cores, we don't think Nvidia will cut the die down. So instead, the GeForce RTX 4070 Ti will likely feature the entire die, meaning that it'll also have 240 Tensor cores and 60 RT cores at its disposal in addition to the 7,680 CUDA cores.

Hardware leaker MEGAsizeGPU, who has a solid track record with Ada Lovelace leaks, claims that Nvidia will launch the GeForce RTX 4070 Ti on January 5. The pricing, however, remains a mystery. Nvidia was originally asking $899 for the GeForce RTX 4080 12GB. However, logic would say that the chipmaker will likely have to lower the price tag given that AMD's Radeon RX 7900 XTX and Radeon 7900 XT, which rival the GeForce RTX 4080, will soon hit the market for $999 and $899, respectively. In addition, many rumors have suggested that AMD is reportedly facing a supply issue; therefore, RDNA 3 stock may be limited at launch, and maintaining MSRP will be challenging.

Just posting my experimental data with RTX 4090 and mfaktc in terms of power consumption vs performance. Power level is easily adjusted on the fly with nvidia-smi -pl <WATTS>, so easy to experiment and get some numbers:

Watt  GHd/day Gd/W
450 = 12526 : 27.8
400 = 12270 : 30.7
350 = 11789 : 33.7
300 = 11134 : 37.1
250 = 10366 : 41.5
200 =  8016 : 40.0
150 =  5416 : 36.1

Efficiency goes up as you reduce the power cap, down to about 250W (83% performance for 55% power).

Hi, what are the key performance metrics that matter for TL performance?
Is it FP64, FP32, FP16 GFLOP count, is it CUDA core count, version?

I have 3060 Ti, undervolted and currently I am chugging ~3000 GHzD/Day with 160w power consumption.
I am considering an upgrade, just wanted to account for TL too, what are the metrics to check. I understand 4090 is the TL king (not looking at PRO cards), but why?

[firejuggler]

FP64 is what matter.
The *speed* is directly related to the core count and FP64. AFAIK, we have not encountered any bottleneck there. Halve the speed of FP64 and double the core count and your production will be the same.
