Nvidia is launching its $1,999 GeForce RTX 3090 Ti today. After a mysterious delay following a January announcement, the “fastest GPU on the planet” will be available from Asus, Colorful, EVGA, Gainward, Galax, Gigabyte, INNO3D, MSI, Palit, PNY and Zotac in stores today. Nvidia has also created a limited edition Founders Edition board that will be available from Best Buy online.
The RTX 3090 Ti is the familiar-looking triple-slot design we’ve seen on the RTX 3090, and both cards look identical at first glance. Nvidia is really maximizing what its existing 8nm GA102 chip is capable of inside the RTX 3090 Ti, coupling it with 24GB of GDDR6X running at 21GB/s. That’s the same amount of VRAM as the RTX 3090 but with a nearly 7.7 percent faster memory clock resulting in a total memory bandwidth of 1008GB/s.
Nvidia says the RTX 3090 Ti will also include 40 teraflops of GPU performance, with a base clock of 1560MHz, and a boost clock of 1860MHz. That’s a bump over the 36 teraflops on the RTX 3090, the base 1395MHz clock, and 1695MHz boost clock speeds. The RTX 3090 TI also includes 10,752 CUDA cores, 78 RT-TFLOPs, and 320 Tensor-TFLOPs.
40 teraflops, Jesus.
It's not that much of an improvement over the RTX 3090, but still...

GeForce RTX 40 series board could smash 100 TFLOPS barrier as leaker doubles down on Lovelace AD102 GPU capability
Leaker Greymon55 has doubled down on an old claim of how capable the high-end AD102-powered RTX 40 series boards could be. A leak from the end of 2020 suggested cards with a Lovelace AD102 GPU (potentially RTX 4080, RTX 4080 Ti, RTX 4090, and RTX 4090 Ti) could churn out 66.4 TFLOPS in FP32 (single-precision floating-point format) at 1.8 GHz. A later claim, made by Greymon55, stated a board with an AD102 GPU could offer 85 to 92 TFLOPS, with clock rates from 2.3 GHz to 2.5 GHz. Now, the same leaker has posted a reminder of this astonishing graphical compute performance, saying “if Lovelace gets up to 2.5 GHz, you’ll get about 90t of FP32”.

Although TFLOPS (tera (trillion) floating operations per second) rate is far from the only way of measuring a GPU’s compute performance and general handling of graphics output, it has become more accessible as a form of quick comparison tool for the wider public, as seen in the recent competition between the PlayStation 5 (10.28 TFLOPS) and Xbox Series X (12.15 TFLOPS) current-gen consoles. Nvidia’s RTX 2080 Ti took the PC gaming world to 13.45 TFLOPS and then Ampere came along and basically tripled that amount with the RTX 3090 delivering 35.58 TFLOPS in FP32 (single-precision floating-point format) and the upcoming RTX 3090 Ti supposedly managing 40 shader TFLOPS.

Early last year, graphics card makers like Asus announced they would be raising prices amid an intensifying GPU shortage. This price hike was partly a result of tariffs imposed on some Chinese products by the Trump administration; the tariffs had been waived for several years but were allowed to go into effect at the end of 2020. Last week, the Biden administration reinstated many of those waivers, and Asus announced Monday that the company would lower its GPU prices as a result.

The price drops will go into effect on April 1 and will apply to the company's entire lineup of GeForce RTX 3000-series GPUs, including the 3050, 3060, 3070, 3080, and 3090 series cards. "Consumers should expect prices to decline up to 25% on different models throughout the springtime," Asus said in a statement.

Asus and other GPU makers have revived (or simply continued selling) many older GPU models—including the RTX 2060 and 1660 and the GTX 1050 Ti—to try to address the ongoing GPU shortage. There's no word on whether we can also expect to see price reductions for these models or if they'll eventually go away as the availability of newer GPUs improves.

I posted about HPC cards, now it's time for desktop cards. GTX 680 costed $500 in 2012 and RTX 4090 will cost $2000 in 2022. $500 from 2012 is $620 in 2022. Even with this large price increase, performance grows with higher acceleration than price. We can safely assume over 1 petaflops in 2032, but for an even higher price. Imagine owning a PC that would be #2 fastest supercomputer in 2008. This will become reality during the 2030s.

12900KS is 4% faster in apps and 2% faster in games than 12900K
it's also more expensive, more power hungry and hotter, so needs better (more expensive) cooling

Today, I quickly made this graph, to answer the important question, of how have Intel desktop CPUs evolved in multi-threaded performance, since the famous i7-2600K. I took Cinebench R15 scores from HWBot.org, so that maximum overclocks are compared. Comparing max OC makes more sense, because 2600K could be OCed by more % than 12700K. Boost clocks have been getting closer and closer to max OC since the i7-4790K. Actually, 12700K overclocks to a lower point than 3770K, which is a shame. As you can see, things are starting to accelerate more so than before. 13700K will double the amount of E cores, while improving performance per clock. I will update this graph once results from overclocking 13700K become available.

EDIT1: I hope this doesn't continue like that, because 4x in 10 years is ... really bad! 4x should take 3 years. If it took 5 years, then I would be still ok with it, but, seriously, 10 long years? It has to change. It just has to. 😟 The graph was improved and re-uploaded.

Ok, so today I made probably a more important graph - how has multi-thread performance of Intel server CPUs changed over the years and how it will change until 2026. Xeon E5540 in 2009 costed only $774, E5740 in 2010 costed $1,980 and E7-8870 costed $4,616. As you can see, price increased by 6x in just 2 years! That's not the end however, because Xeon Platinum 8180M in 2017 was priced at whoppingly 13,011!! 😬 That's almost 17x more than 8 years earlier!! However, thankfully to increased competition, it came down to $3,950 in Q1 2020, while performance improved by 8%. Sapphire Rapids will cost about $10,000 and Diamond Rapids once again $13,000 (but it will have 144 cores). So performance/price (without taking inflation into the calculation) will improve by ~10x between 2009 and 2025, which is not a lot for 16 years in my opinion. YoY performance growth between 2020 and 2025 will be substantially better than between for example 2015 and 2020. Expect around 10x between Ice Lake (2021) and Diamond Rapids (2025). In fact, it will be remarkably good in pure performance metrics. 10x in 4 years could after all mean 100x in 8 years, but we'll see.
