Try it and then judge it. Don't judge it before trying it out.

"Funny" isn't a measure. Only "true" and "false" are measures.

Yes, but the source you cited also states that AVX-512 on Zen5 will be severely limited by cache-and-memory bandwidth. In other words, in a real-world scenario it is unlikely for AVX-512 in Zen5 to outperform AVX-512 in Zen4 by a large margin - unless the dataset can fit in Zen5's L1D or L2 cache.

Do this please: Ask ChatGPT/Gemini/etc whether it is possible for a single Linux/Windows process to utilize 32-bit and 64-bit libraries.

You should have checked publicly available databases before posting the above misleading statement. The truth is that FLOPS of modern CPUs such as Ryzen 7 9700X (year 2024), when all CPU cores are running at 100% (5GHz*8*2*512/32=1280 GFLOPS, AVX512), is roughly equivalent to a mid-range GPU in...

It is a misunderstanding of how CPUs and operating systems work. A single app cannot be switched from 32-bit to 64-bit mode or vice versa. Neither the CPU, nor the OS, supports this. Mixing 32-bit and 64-bit libraries is not possible in a single process. You would need to have 2 apps...

Evidently, 3 slots wide mid-range GPUs are the norm now. What is next: 4 slots wide high-end GPUs? Or the GPU cooler and fans extending 3 centimeters above the 3 PCIe brackets? 1kg tower cooler to be mounted on a GPU?

There is no proof that you have some knowledge about what machines in particular are involved in the manufacturing of Zen3/4/5 CPUs. Besides, you never said that they DON'T share EVERY machine when manufactured. Logically, pointing out differences after you claimed sameness cannot be...

Ryzen 7000 CCD manufacturing process is N5. Ryzen 9000 CCD is N4P. This suggests that some of the machines used during manufacturing are different. Ryzen 7000 3D V-Cache connections are physically incompatible with Ryzen 9000. Zen3/Zen4 3D V-Cache chiplet is manufactured on a 7nm process node...

Evolution of CPU prices after launch is determined by market forces. AMD's MSRP is just a suggested price. Ryzen 7800X3D is today above MSRP and costs almost the same as 7950X. Thus, $550 market price for 9800X3D at launch is realistic. If 9800X3D started selling at the same (or lower) price as...

You slightly misinterpreted what was said in that interview It doesn't matter what you believe is supposedly true or false about Zen5 if I can disprove the claim by running actual code on my Zen5 CPU For example, I can measure an IPC of ~8.84 on Zen5 in a synthetic single-threaded benchmark...

The above is misinformation, probably caused by not having access to a Zen5 CPU on which you could test your ideas before posting. A single thread on my Zen5 CPU can execute 2 *taken* branch instructions per cycle, if the outcomes of both branch instructions have been successfully predicted...

It is a valid approach. However, there exist alternative approaches. It is fairly simple in a market economy to correct a demand-exceeds-supply disequilibrium: gradually increase prices in order for demand to match manufacturing capacity. The other way around: When supply-exceeds-demand...

It is extremely unlikely for chip manufacturing defects governed by laws of physics and chemistry to perfectly match (1) AMD/Intel's market segmentation, (2) market demand or (3) distribution of wealth in a society. ---- I mean it in the following sense: If AMD/Intel were serious about...

Silicon that is disabled, but is nevertheless present on the chip and is otherwise fully functional, is a waste of natural resources and a waste of chip manufacturing capacity.
