Intel Adds More L3 Cache to Its Tiger Lake CPUs
InstLatX64 has posted a CPU dump of Intel's next-generation 10 nm CPUs codenamed Tiger Lake. With the CPUID of 806C0, this Tiger Lake chip runs at 1000 MHz base and 3400 MHz boost clocks which is lower than the current Ice Lake models, but that is to be expected given that this might be just an engineering sample, meaning that production/consumer revision will have better frequency.
Perhaps one of the most interesting findings this dump shows is the new L3 cache configuration. Up until now Intel usually put 2 MB of L3 cache per each core, however with Tiger Lake, it seems like the plan is to boost the amount of available cache. Now we are going to get 50% more L3 cache resulting in 3 MB per core or 12 MB in total for this four-core chip. Improved cache capacity can result in additional latency because of additional distance data needs to travel to get in and out of cache, but Intel's engineers surely solved this problem. Additionally, full AVX512 support is present except avx512_bf which supports bfloat16 floating-point variation found in Cooper Lake Xeons.

Nominal temp at 5ghz and 1.5v++ would be under 50c at load.
The higher the clocks, the colder you go.
I have lots of example screen shots of different temps and cooling of various FX chips.
The high leakers like FX 9590 respond well to cool water delta. Think my max was 5.6ghz on geothermal loop. Cheating with cutting cores does help too.
cooler-
CPU/NB is IMC or Integrated memory controller.
55 in gaming at worst 75 on blender

Usually an air cooler on FX at 5ghz just isnt doable. Your chip must be a low leaker.
