Nvidia announces RTX 3090 Ti with faster memory and performance

Jan 4, 2022, 11:35am EST

Nvidia is announcing a new flagship GPU today, the GeForce RTX 3090 Ti. While the wait continues for Nvidia’s Ampere successor, the RTX 3090 Ti is here to prove Nvidia can still squeeze more performance out of its existing 8nm GA102 chip.

Nvidia is only teasing the RTX 3090 Ti today, and it’s the familiar-looking triple-slot design we’ve seen on the RTX 3090. Both cards may look identical, but inside, the new RTX 3090 Ti will include 24GB of GDDR6X running at 21Gbps. That’s the same amount of VRAM as the RTX 3090 but with a nearly 7.7 percent faster memory clock, providing additional performance for 4K gaming and AI tasks.

Nvidia says the RTX 3090 Ti will also include 40 teraflops of GPU performance, around 11 percent faster than the RTX 3090 with 36 teraflops. There’s also 78 teraflops for ray tracing and 320 teraflops for AI tasks. Nvidia hasn’t detailed base and boost clocks, but it certainly looks like the RTX 3090 Ti will be around 10 percent faster than the RTX 3090 on paper.

Just how much this extra performance will impact power requirements isn’t clear yet, either. Rumors suggest the RTX 3090 Ti could require a 1000W PSU, with a TDP of 450 watts. If accurate, that’s 100W more than the RTX 3090 in terms of power draw and a big bump to the 750W recommended PSU.

All of these numbers mean very little without game benchmarks or pricing, though. Nvidia isn’t sharing these details today, so we’ll have to wait on detailed reviews to see how well this card performs against the RTX 3090 and AMD’s Radeon RX 6900 XT. Given the RTX 3090 debuted for $1,499, we wouldn’t be surprised if the RTX 3090 Ti launches around the $2,000 mark.

CES: Intel Announces Core i9-12900KS at 5.5GHz and 22 Other Alder Lake CPUs

By Joel Hruska on January 6, 2022

If you’ve been interested in Intel’s new Alder Lake platform but have been waiting for the company to launch its mainstream parts, we have good news. The chip giant took the lid off its mainstream Alder Lake family at CES this year, from the Core i9-12900 all the way down to some basic Celeron options.

[...]

Separately from its large Alder Lake launch, Intel announced a new, ultra-high-end CPU: The Alder Lake Core i9-12900KS. This 8+8 CPU will feature a 5.5GHz maximum clock speed and an all-core boost of 5.2GHz. The latter is more impressive than the former. Single-core boost clocks are all but meaningless in an age when most applications are at least dual-threaded. An all-core 5.2GHz boost implies that customers should see at least that speed under full load.

There is a really interesting article on Next Platform on the past 10 years and the next 5 years of Intel server CPUs. Price/performance got worse between 2012 and 2019 (!!). Sandy Bridge top bin part costed only $2057, while Skylake top bin part costed a whooping $13011 (!!). Cascade Lake in 2020 brought the price down to $3950 (because of AMD EPYC). The dark ages of CPUs seem to be behind us. In front us is Sapphire Rapids, Emerald Rapids, Granite Rapids and Diamond Rapids which will have 144 cores at 2.7 GHz, AVX-1024 instructions, AMX 2 matrix engine, 288 MB of L3 Cache, DDR6, PCI-E 6.0 and will be 10.15x faster than current Ice Lake or 65,56x faster than Sandy Bridge from 2012. Xeon SP v7 on the "Mountain Stream" platform in 2025 will be 167.18x faster than the Nehalem Xeon X5570 server processor from March 2009. That's over 7 doublings in a span of about 16 years. Price will be 938% higher (not adjusted for inflation) than the 45nm 4 core 8 thread Xeon X5570. If not for competition, Diamond Rapids would probably cost around $30,000. IBM and Fujitsu also offer alternatives. There are upcoming ARM server processors with more performance and more cores. IPC improvements in 2024 and 2025 will be greatest since the 1990s for Intel. It is likely that CPUs will reach 1024 cores in the 2030s. AMD is equipping server CPUs with 3D stacked extra cache. It is also likely that L3 cache will be counted in gigabytes in the 2030s. I think it would be better to sum L2 and L3 cache, Intel has similar amounts of L2 and L3. Intel increased L2 cache from 2 to 14 (!) MB between i9-9900K and 12900K. L3 cache nearly doubled. Corecount increased from 8 in 2018 to 16 in 2021 to 24 in 2022 (Raptor Lake i9). Frequency is improving by 100 MHz a year on average. From 5 GHz in 2017 to 5.5 GHz in 2022 and 6 GHz in 2027. I just hope that prices will remain sane and only increase as much as inflation.

Global economy doubles in product every 15-20 years. Computer performance at a constant price doubles nowadays every 4 years on average. Livestock-as-food will globally stop being a thing by ~2050 (precision fermentation and more). Human stupidity, pride and depravity are the biggest problems of our world.

There is a substantial progress in AMD GPU single-core performance in recent years. From 1050 MHz in 2015 to 2815 MHz in 2022. Vega architecture in 2017 added half-precision and RDNA 1.0 in 2019 improved IPC (instructions per clock) by 25%. Higher single-core speed allows for more calculations per pixel or per object. To counter Amdahl's Law, GPUs also need better single-core throughput and not only more compute units. Total cache capacity has also increased exponentially, from 3 MB in 2015 (Fury X) to 136 MB in 2020 (6800 XT). Unfortunately, prices of new graphics cards have been on the rise.

Cost of Intel's 10 cores has been dropping exponentially:
Image
I opted for using Xeons instead of i7-6950X. I think it's likely that i5-13400 will be a 10-core and will cost just that by the end of this year. Later we can expect 10-cores falling into i3 territory.

VRAM Capacity chart (10 years) in lowest-end gaming graphics (dGPUs) cards from Nvidia and their AIB (Add-in boards) manufacturers. Assuming there will be no lower capacity version of RTX 3050. I personally can attest that with less than 8 GB of VRAM there are problems in multiple games, even older ones when you add mods. Some games do require 16 GB to work without problems. More is better.

PCI-Express 4.0 came out in first PC motherboards in 2019 (Zen 2, X570 chipset), PCI-Express 5.0 in 2021 (Alder Lake, Z690 chipset) and PCI-Express 6.0 is expected in 2023 (or 2024) on desktop and 2024 on server. For example new Transcend M.2 2TB SSD achieves up to 7.4 GB/s read speeds trough PCI-E 4.0 x4. Some GPUs have offer slight improvements in performance through PCI-E 4.0 x16 over 3.0 x16 and larger improvements when the number of lanes is lower than 16.

PCI-E 6.0 interface can be useful for servers, AI/ML, networking and storage in data-intensive markets like data center, HPC, industrial, automotive, military and aerospace. Hard to say if this exponential trend will continue uninterrupted after PCI-E 6.0 which will allow for 256 GB/s bandwith over 16 lanes (64 GB/s over 4 lanes which is the common number of lanes in SSDs). PCI-E 6.0 specification has already been officially released by PCI SIG : https://pcisig.com/pci-express-6.0-specification.

Jarrod'sTech made a helpful comparison between different i5 processors. As you can see from this YouTube screenshot, the new i5 is 2x faster than the i5 from 2017. Perhaps we can expect the same 2x improvement from i5 four years later (16600K?). I'd like it to be more than that, but I don't know if that's realistic. Maybe if the upcoming IPC gains are >30%. I'd say that at least 2x and it's not impossible to be 2.5x or 3x.
