About extrapolating things.

Post by Tadasuke »

Extrapolations aren't the safest action and they don't have to come true. CPUs went from 1 core to 4 cores between 2004 and 2006. Server CPUs got to 8 cores in 2010 (AMD's mainstream to 6) and mainstream CPUs in 2017 (i7 in 2018).

$266 Q6600 from July 2007 is 20x slower according to PassMark than the current day Ryzen 7 7700X which is about the same price. It has 2x more cores and 4x more threads, which is not that many more. According to Moore's Law, equivalent CPU in 2023 could have 2^8=256 times more cores, which would be 1024 cores. The highest core count this year will be 128 for the highest-end server CPU (AMD Bergamo) so we are far from that.
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.

The Incoming Nvidia RTX 4070 Only Consumes 186W in Gaming
That's roughly equivalent to an RTX 3060.

Nvidia's upper-midrange RTX 4070 is supposedly in reviewers' hands as we type this, and it's expected to launch on April 13. So far, it's been confirmed that it will be priced at $599, the same price as the Ampere-based RTX 3070 Ti, and $100 more than the RTX 3070 when it launched. Despite the price hike, it sounds like a very efficient GPU. New leaked specs posted by Videocardz show it consumes just 186W while gaming, roughly the same as an RTX 3060.

some different CPUs comparison from tenstorrent

Post by Tadasuke »

186 watts for a lower-mid-range graphics card is quite a lot in my opinion. Just a reminder that GTX 970 was $329 in 2014 and even less later ($299 for example).

Here's an alleged comparison of different companies single-threaded integer performance of different CPUs. There are Amazon CPUs, AMD CPUs, Nvidia Grace CPU, Intel CPUs and tenstorrent CPUs, according to tenstorrent. Zen 5 looks to be 2.056x faster in single-threaded than Zen 1 server CPU and 30% faster with 5% higher clockspeed than Zen 4. Kim Keller, who showed these slides, was the man leading the whole Zen team at AMD and they work on processors years before the are actually available for purchase. Earlier this year, I've seen a comparison showing Zen 4 being 2x faster in single-threaded than Zen 1 and 6x faster in multi-threaded, while Intel Sapphire Rapids being 1.5-1.6x faster than Skylake in single-threaded and 3-3.2x in multi-threaded. I don't know. There seem to be varying info. 96 cores Zen 4 has almost 3x higher MSRP than 32 cores Zen 1, I don't know about 128 core Bergamo. I own one old server Xeon, but that's it. I don't own any server CPU from recent years to check any benchmarks.

achieving stable 60 fps in modern games - the cost-effective way

Post by Tadasuke »

From what I've seen over the years in various written tests and on YouTube, if you turn off all unnecessary backgrounds tasks, then all you need for stable 60 fps in modern games from the last 7 years or so, is 7700K @ 5 GHz, so 4-core Skylake architecture running at 5 GHz with two-way multithreading. Or, if you want a new CPU, then choose 12100F which has lower clocks, but higher per clock performance and a low price of only $75 (as of 07/04/2023). Take for example Assassin's Creed games from Unity onwards (which are all on the same AnvilNext 2.0 engine). With 7600K (or 8350K), you won't get stable 60 fps, but with (overclocked) 7700K you can, same with (stock) 12100F. Alternatively, Ryzen 3600 can be chosen with lower single-threaded, but higher corecount and threadcount, probably giving similar results. GPU 6600 XT, 6650 XT, 6700 XT or 6750 XT. Anything below 6600 XT will certainly cause you framerate problems. :D

Overclocker Takes AMD's Ryzen 7 7800X3D to 5.4 GHz on Launch Day
You'll need an Asus motherboard and a bit of luck to reproduce the results.
By Josh Norem April 6, 2023
https://www.extremetech.com/computing/o ... launch-day
AMD's latest salvo across Intel's bow is launching today, April 6, and already overclockers are taking it to heights never envisioned by Team Red. The Ryzen 7 7800X3D is the final V-Cache CPU in the Zen 4 lineup, and at $449, it's by far the most attractive chip yet due to its gaming performance parity with much more expensive CPUs, including AMD's own Ryzen 9 SKUs. However, its extra cache has caused AMD to lock down overclocking on the chip to prevent constant thermal throttling. An overclocker has figured out a workaround for this issue, taking a single core up to 5.4GHz, 400MHz beyond stock.

SkatterBencher is a well-known Asus extreme overclocker. He strapped the Ryzen 7 7800X3D to an Asus ROG Crosshair X670E motherboard with two external clock generators for overclocking. This advanced function lets you disable the CPU's base clock limits and generate new ones for overclocking CPUs with limitations set up by the manufacturer. For example, this was previously used to allow overclocking of non-K (non-unlocked) Intel CPUs. Using these clock generators, AMD's Precision Boost Overdrive (PBO), and AMD's Curve Optimizer, he was able to overclock the CPU to the same maximum boost clock as its non-V-Cache sibling, the Ryzen 7 7700X.

Google's WebGPU API Accelerates Graphics in a Web Browser
It'll be supported in ChromeOS, macOS, and Windows in Chrome 113, which is due in a few weeks.
By Josh Norem April 10, 2023
When we think of a game offering killer graphics, it's usually because we're running it off dedicated hardware instead of in software like in the olden days. Now Google has officially unveiled a new API for its Chrome browser called WebGPU that will let your GPU handle some heavy lifting when running games and other GPU-based workloads. The new API will be enabled by default in Chrome 113, which is currently only offered in the beta channel. It's expected to receive a public release in a few weeks, and Google will also expand its availability to other browsers in the future as well. WebGPU can run on Windows, ChromeOS, and macOS, but it'll also come to Android and Linux in the future.

more on the topic of holding stable 60 fps in modern and future games

Post by Tadasuke »

Below is a screenshot from a Hardware Unboxed YouTube video, showing how 2017 CPUs perform in a 2017 AAA video game. DRM has an impact on the CPU unfortunately, but what can we do about it? Future games probably won't be less demanding than AC Origins. You don't want to be barely at 60 fps (look at the 1% lows). Other than OCed Core i7-7700K, also 8400, 8500, 8600, 8600K, 8700, 8700K, 9400, 9400F, 9500, 9500F, 9600, 9600K, 9600KF, 10400, 10400F, 10500, 11400, 11400F, 12100, 12100F, 12300, 13100F, Ryzen (AM4) 3300X, 3500, 3600, 4500, 4600G, 4600GE, 5500, 5600, 5600G, 5600GE and 5600X will probably all grant 60 fps 1% lows and even 0.1% lows (assuming no extra tasks running in background). I've seen examples that in some heavy-action many-player online matches, Ryzen 3100 was dropping below 60 fps, while Ryzen 3300X was just above 60 fps (in 1% lows). So there you see. It is entirely possible that future games will require at least Ryzen 3700X/9900K or so, console CPUs are about equal to Ryzen 3600 probably, but on PC you also get DRM and possible background processes which tax CPUs more than games on consoles.

Nvidia 'Blackwell' Architecture Rumored to Use TSMC 3nm, Up to 2.6X Faster Than RTX 40 Series
Nvidia will also stick with a monolithic design, for now.
Image
By Josh Norem April 10, 2023
https://www.extremetech.com/gaming/nvid ... 26x-faster
Given the company's two-year release cadence, Nvidia's next-generation Blackwell architecture is due in late 2024. Despite that timeframe, sources inside Nvidia are already discussing what it might bring to the table, according to several YouTube tech journalists. The most interesting revelation is that Nvidia will likely stick with a monolithic die for the 50-seres GPUs instead of switching to a chiplet design similar to AMD's 7900 series. These sources said that based on the performance and issues with AMD's first chiplet-based GPUs, they have no interest in going down that path, at least for now. Nvidia will likely use chiplets in future HPC GPUs, however.

YouTubers Moore's Law is Dead and RedGamingTech have reportedly been talking to Nvidia insiders, and they have much to say. Notable Twitter tipsters are also starting to chime in with Blackwell info, and Wccftech has collected this batch of rumors. The big news is that, like Ada Lovelace, Blackwell will be a quantum leap forward for Nvidia as it moves from TSMC's 4/5nm process to the much-hyped 3nm node. This could allow it to deliver a 2-2.6X performance improvement over its current GPUs, even with a monolithic design. The flagship GB102 is expected to offer just 144 SMs, the same as AD102. Therefore, the advancements will come not from throwing more hardware at the problem but from a new, more efficient design.

some graphics cards comparisons at a constant price

Post by Tadasuke »

According to Nvidia's marketing? Sure.
In real-world use? No way. Zero chance.

I made a comparison of $599 GPUs (graphics cards) from different years, so you can see, how they have been changing since 2010. Real-world performance improvement (7.29x) is very much in-line with CPU performance improvement at a constant price. There is a stagnation in gigapixels and VRAM since 1080 Ti, which was going for about $599 in 2018. Performance has been rising by 16.5% year over year on average. In-line with my moderate growth prediction (between 10 and 49%). This is also about as much as the new Ryzen 7800X3D is faster than the 7700X from 2022 (at the same price). Expect a 35.7% faster card (I don't mean flops) at the same price in 2 years (probably RTX 5070).

Snapdragon 8 Gen 3 GPU Could be 50% More Powerful Than Current Gen Adreno 740

Post by Tadasuke »

An online tipster, posting on the Chinese blog site Weibo, has let slip that Qualcomm's upcoming Snapdragon 8 Gen 3 mobile chipset is touted to pack some hefty graphical capabilities. The suggested Adreno "750" smartphone and tablet GPU is touted to offer a 50% increase over the present generation Adreno 740 - as featured on the recently released and cutting-edge Snapdragon 8 Gen 2 chipset. The current generation top-of-the-range Snapdragon is no slouch when it comes to graphics benchmarks, where it outperforms Apple's prime contender - the Bionic A16 SoC.
