Cezanne Stretches Its Legs: AMD Ryzen 7 5800H System Benchmarked
AMD's Zen 3 core has seen some major performance uplift, with the first products based on it being the 5000 series desktop processors codenamed "Vermeer". With the efficiency that this new core brings and IPC increase, it is only a matter of time before it scales down to mobile processors. Today, thanks to the findings of TUM APISAK, we get to see some performance results of AMD's upcoming Ryzen 7 5800H "Cezanne" processors. Benchmarked in the Geekbench 5 test suite, the CPU was spotted running at the base frequency of 3.20 GHz, and boost frequency of 4.44 GHz. This is only an engineering sample so the real product may have different clock speeds.
The CPU managed to score 1475 points in single-threaded results while having 7630 points in a multi-threaded scenario. If you wonder how does it fare to the last generation that it replaces, the Ryzen 7 4800H scored 1194 points for ST, and 7852 points for MT. That means that the new Ryzen 7 5800H CPU has a 23% performance boost for ST workloads, showing the Zen 3 capability. The MT score is not representative as we do not have the final product yet, so we have to wait and see how it performs when reviews arrive.

H-series are low-yields that result from leaky silicon that clocks high with added voltage but isn't efficient. The really high profit margins are in the premium U-series ultrabook space where it's okay to charge $1500 for a 15W CPU model that relies on integrated graphics, because it's lightweight and promises all-day battery life from its efficient CPU. Hell, lots of companies slap $5 of carbon fibre somewhere and decide that it's worth selling at an extra $400 compared to their regular aluminium models of the same spec.
Also TGL has advantage with +8.5% core freq and LPDDR4-4133 on board.
As for Zen 3 vs TGL, I simply don't understand all these AMD fanboy comments. These guys have no clue about how each architecture stacks up and still thinks Intel is at Skylake level and AMD did some wizardry and gained 200% of IPC in 3 years. Reality check guys, Zen 2 is 5-10% better in IPC vs Skylake. Yeah, that 2015 architecture. And Zen 3 adds 20% over that, but TGL also add 20% over that, so the delta between Zen 3 and TGL is the same as Zen 2 vs Skylake. What is so hard to understand??? Add to that the fact that like with Skylake vs Zen 2, TGL clocks higher (4.8Ghz ST) vs 5800H at 4.3-4.5Ghz ST, so you get very similar ST performance. If that doesn't clear things up, than you are either dumb or AMD fanboys.
Now let's take a valid TGL entry - click. Five ST tests in row.
ps. One more Cezanne
