I posted a bunch of benches with 12-20% advantage for the 7950X in those 105/125W comparisons but you're accusing me of cherry picking a benchmark? Isn't that what you just did with the Pov-Ray bench? Funny thing is though in Pov-ray where intel are 12.6% faster at stock, the 7950x becomes 36.8% faster at 35W and still 20% higher in your flawed pts/watt approach. Do you see what this says for scaling? See the two graphs and draw two lines.Ah, so you are saying that if you cherrypick specific benches from specific reviews at whatever power limits helps your argument you might come to your preconceived conclusion. Let's totally ignore computerbases review which actually measure average power draw...
So, back to Anand tech.
Povray @35w = 147pts per watt for the 7950x, 124 for the 13900k
Povray at 65w = 115 pts per watt for the 7950x, 118 for the 13900k
Let's go for power normalized then, 83pts per watt for the 7950x at 105w, 78 for the 13900K at 125w. The difference is LESS than 10%.
Keep up the defense
I'm not being defensive at all, i'm literally just pasting a bunch of numbers but you seem awfully agitated and accusing others of spreading propaganda and not knowing math and what not. You also seem to be cherry picking and then strangely accusing others of doing the same. I'll ignore that, let me just summarize all the Anandtech benchmarks simply because i have the numbers and I don't really want to continue this discussion any further. Here are the 35W numbers, since 7950X is faster in all of them i'll just state by how much.
Cinebench: 53%
C-Ray: 38%
Pov-Ray: 37%
Blender B: 35%
Blender C: 40%
Blender F: 40%
X264: 66%
X264 4K: 67%
Average: 47% faster
Since the 7950X is at 45.1W vs the 13900K at 39.3W, we can sort of factor in your pts/watt calculation with a base of 100, which would put the 7950X 28% higher. Again, keep in mind this calculation benefits the 13900K, as it's sitting lower in the v/f curve. In reality, it's easily >30% higher.
So the 7950x is ~30% more efficient than the 13900k at 35W, as seen in this review/suite of benchmarks. Good? I hope so, as it's all just numbers.
