What we noticed during testing
We took a little more time to counter some of the anomalies we noticed when benchmarking the new Kaby Lake-X CPUs. To what extent the 3DMark can really be a reliable reference, let's face it. However, the following results are reproducible on the mainboard. The test, which we repeated over and over again under different conditions, shows very clearly that the DrawCalls per second showed a huge disadvantage of the Core i7-7740X, which could not even be lifted in the extremely overclocked state. :
We will see later, also in some workstation tests, that we occasionally came across such disadvantages of the Kaby Lake-X CPU again and again exactly when it came to a predominantly graphical output, while the compute parts did not raise any questions. and perform as you might have expected. Whether the problem is chipset-related, or whether the drivers have made a dash through the bill, we can not answer exactly today, but only guess.
An example where such weaknesses as in API overhead did not play a role, for example, is The AI test of Civilzation VI (under DirectX12). Here the pure beat before the thirst goes at the socket and so the overclocked Core i7-77400X then wins quite clearly. There is no trace of the oddities that have just been noticed.
Battlefield 1 (DX11) and GPU Limitation
We also intentionally built in a supposed lapsus, because we deliberately let all CPUs run into the GPU limit. But already with the Min-FPS there are interesting (and reproducible) outliers.
This difference continues with the frametimes and their variances. However, the Uneveness index most closely suited to subjective sentiment gives a warning: Whether Intel or AMD, no CPU provides unpleasant scenes or subjectively perceptible hangers.
