Assuming a core isn't starved by low memory bandwidth and uncore/IMC/L3 cache speed, the performance increment should generally be linear with increasing core clock speed. Then I use this rough formula to calculate the IPC difference.
i7-1165G7: 6737 single core score / 4.7 GHz = 1433 score per GHz.
R7-4800U: 5531 single core score / 4.2 GHz = 1317 score per GHz.
1433 / 1317 = 8.8% higher IPC with i7-1165G7. only 8.8%!? Dayum!
(scratching my head)This is weird. As far as I have read that the Ice Lake itself has at least 10% better IPC than even the Zen 2 desktop part. Either the Intel one isn't reaching 4.7 GHz turbo or it's the 4800U going more turbo than 4.2 GHz? [or] the 4800U is running with faster RAM or the benchmark is biased toward Intel?
Also why use GB4 when GB5 is here? Is there any special reason to not use GB5?
