That's an improvement of 12.5%, that's not that much (especially considering the skipped Gen 10).
That's incorrect reasoning.

You got 2x gains going from 24EU Gen 9 to 64EU Gen 11, while the bandwidth increased 55%. That's because things don't scale linearly.

Bandwidth increases only by 33% while the shader throughput increases by 77% for Elkhart Lake.

If you want double the performance in a balanced uarch, you need to double the bandwidth, the fillrate, and the shader throughput.

You agree yea?

It means Gen11 is making better use of available bandwidth.
Something like that.

Prescott Pentium 4 was not faster than Northwood.

Yet on Celerons, it was 25-30% faster per clock.

Same thing with current CPUs where Core class chips are seeing 15-20% gains but Atom-class chips are getting 30%.

That's nice and all. My point was that whereas the platform balancing optimizations are all commendable the architecture improvements appear to be negligible. That the Cores are even worse doesn't make it any better.

Architectural improvements(larger caches, tiling) are why it can perform greater than specs suggest.

Gemini Lake Refresh J5040 gets 95 points in Cinebench R15 1T. That's a 15% improvement. That's a 3-4% higher than specs suggest. It must not having been reaching boost as reliably.

Improvement will be less in MT. Seems to be 5-7%.

Hmm, do we have any idea what kind of average clock it's hitting in ST and MT?
