Metrics are designed to convey information in an easy to compare way. But when the wrong metrics are used they can be misleading. When former Anandtech writer Ian Cuttress was doing energy comparisons and was showing AMD in good light, the AMD fbs were cheering. Now they don't like it and complain about changing metrics. In any case using power to claim efficiency is incorrect. Energy is what is important here and Energy=Power x time. In Layman’s terms if my CPU uses twice the power than yours but (due to higher clockspeed and higher IPC) manages to complete the task in half the time, it will consume the exact same energy as yours while also saving me half the time. Now you may be wondering where power is relevant. Power is relevant in cooling. If two cpus have the same die size and the same cooling solution, the higher the power of a cpu the hotter it will run (thereby necessitating the use of a better cooler). If you look at the physics of heat transfer or simply a thermal equivalent circuit, you will understand why.
That's wrong. IPC advantage of Golden Cove over Zen 3 is something like ~10%. Making IPC claims on the basis of a single app is pointless. Referencing TPU is pointless as well. They are using DDR5-6000 for Intel, 25% over the supported specs. Normal SR servers won't use such memory. They also seem to use a bad AM4 system. The 5950X doesn't even score 26k in CB23. On a good configured AM4 system the 5950X can score around 29k in CB23.
1. I already said in my original post that IPC is a per workload metric. I used Cinebench as it is a popular benchmark that its performance is almost completely invariable of RAM configuration. I find it funny how AMD fbs are now rejecting Cinebench as a benchmark and suggest looking at other benchmarks while for years Cinebench was THE TRUTH and were making fun of Intel when Intel said to look at other benchmarks. Double standard hypocrites of the highest order.
2. You are quoting my follow-up post which was a response to the claim that the best configuration for Alderlake in Cinebench is with Win10 and DDR4 and that it was supposedly only showing 13% difference. Which demonstrably is not true. As for Techpowerup’s testing in particular, the memory configuration used was the best for each platform for a dual channel 2x16GB setup. On AMD they used 2x16GB DDR4 3600C16, also above spec. And dual rank memory which benefits AMD.
3. For Intel, Cinebench scores do not vary with RAM almost at all. If in doubt look at benchmarks in various reviews that did both testing with DDR4 and DDR5 as well as with different RAM frequencies. We are talking about variation of 50-60 points at most and Cinebench scores vary a little from run to run for other reasons anyway. As for the MT score of the 5950X every good reviewer, in their benchmarks of the 5950X had its MT score in CB R23 around 26K. The 28K or higher scores you are seeing in some benchmark databases are with PBO enabled or OCing. It is not stock performance.
Unlikely. Genoa ES are floating around for quite some time. I guess it will be launched very closely to Raphael. Which means somewhere in Q3. It makes not much sense to launch Genoa at the end of the year when Bergamo is expected early next year.
We will see whose prediction is right. As for Genoa ES floating around and all I should remind you that at the beginning of June 2021 AMD demonstrated a working 3DVcache 5900X implying it will come later in the year only to never come to market and eventually launch a 5800X3D 9.5 months later. AMD may announce/show Genoa in Computex but I doubt we will see an actual launch prior to November-December. Certainly not in high volume. And that's based on TSMC's 5nm yields and capacity.
just fyi there is a leaked benchmark.
Latest benchmarks of Intel's Sapphire Rapids-SP Xeon ES CPU shows lackluster performance against AMD's EPYC Milan processors.

spoiler: it's not looking too good.
The same benchmarks also show SPR performing 25% worse in MT than Icelake despite having 40% more cores. It is obvious that there is an issue with the ES SPR two-socket system tested. The scores look as if only one CPU is enabled. We will see.
