Ne ovat selvästi heikommat kuin HardwareLuxxin ja meidän ajamat testit.
Todennäköisesti BIOS-vika, ei ole boostannut mihin pitäisi tms.

päivitys uudella mikrokoodilla.
"In our CPU performance tests, we are seeing an average +1.8% performance gain across all workloads. This varies between a -4.3% loss in some workloads (Handbrake) up to a +9.7% gain (Compilation). SPEC2017 single thread saw a bigger than average +3.4% gain, however SPEC2017 multi thread saw a -2.1% adjustment, making it slower."
"In our GPU performance tests, using our RTX 2080 Ti, we are seeing an average +3% performance gain across all configurations. In one case at low resolution settings it was as high as +12%, however +2-3% was typical at 1080p maximum quality."
Ja tässä ehkä syy miksi tulokset parani:
"The L1 cache structure remains at 5 cycle vs 4 cycle, as expected, and the L3 is also as expected, with 13 cycles, similar to the Ice Lake design. In our 0x2C test, the L3 latency was 50.9 cycles, but with the new microcode is now at 45.1 cycles, and is now more in line with the L3 cache on Comet Lake. Despite this change however, we saw no adjustment in core-to-core latency.
Out at DRAM, our 128 MB point reduced from 82.4 nanoseconds to 72.8 nanoseconds, which is a 12% reduction, and more in like with the Comet Lake memory latency response.
It is worth noting that our 12% reduction in DRAM latency is not the +40% reduction that other media outlets are reporting. Whereas others use commercial tools, we feel our internal tools are more accurate. Similarly, for overall DRAM bandwidth, we are seeing a +12% memory bandwidth increase between 0x2C and 0x34, and not the +50% bandwidth others are claiming. (We do see a +50% bandwidth increase from 0x1B to 0x34, but between 0x2C and 0x34 it is only 12%.)"
AVX512 turbotustakin on rajoitettu:
"On our second motherboard with the 0x34 BIOS, the frequency of the processor under AVX-512 started at 4.6 GHz, but within two seconds dropped to 200 MHz lower, running at 4.4 GHz. This meant that the chip experienced 276 W peak power, which very quickly dropped to 225W. At the peak, "
Ja vuodetuista slidesitä poiketen niiden uuden ja vanhan mikrokoodin emoilla 11700K on 1:1 muistijakajalla 3200mhz kelloilla, eikä huhutulla 1:2.
"It should be noted that on all of the motherboards we have tested, all BIOS versions, the actual default operation for a Core i7 running at DDR4-3200 does appear to be the 1:1 mode. For the avoidance of doubt, in our testing on every microcode to date, all of our motherboards were running at a 1:1 ratio."
