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.

Hornestly in tired of seing Intel quad-core after quad-core. Thats how they released i7 for almost 10 years for desktop. This CPU is properly for laptop/small lowpower desktop pc. I want to see Intel be more innovative than they Are now.
Amd has really been way more innovative with there ryzen 3000 line up and threadripper 7 nm based chip. I think amd will be more interesting this round than intels next hedt line up as well as there comet lake lga 1200 socket chips.
Larger silicon die will seriously cut in to Intel's profits, at this point Intel is desperate when they realized that 10nm is not going to save them from AMD's 7nm+ EUV.
Only thing Intel can do now is continue lying and using inaccurate data in the press to try holding back AMD from cutting in to the big market share they have in notebooks but rest assured that AMD is coming for that too in a big way next year.
Their process is still having massive yield and quality issues it seems. Apparently, they are doing some questionable marketing of the new chips to keep the investors happy on the mobile side of things. Trying to hide negative performance scaling.
Good to see both Intel and AMD focusing on more IPC instead of arbitrary 5Ghz mark.
If it suits you that's fine. Personally i could not use it in this day and age.
That is the only way to control the 200W heaters we have by our feet.
Competition is the only way to make bigger gains, and Intel still has none for single core (not to mention you can't really OC ryzen 3000 and Intel chips OC like a beast even on big air heatsinks like Noctua) further widening the gap.
There is still a sizeable market for quad core CPUs. Not everyone needs 8 cores. Unless you are playing certian games, even 6 cores has little tangible benefit outside of the creative market. Until that market decides it suddenyl needs more power, quad cores will still sell well,a dn will still be intel's consumer bread and butter.
But I dissagreed about quad-core for gaming, specially if its with out HT/SMT. games these days needs at least 8 threads or cores to run properly. Many reports stutter in new games running quad-cores and certain if the CPU only has 4 threads as well. More and more games Are getting optimized for 6 cores and some games Even benefit from 12 threads.
I would never reccoment or Buy a quad-core CPU for gaming today. Caretainly if you have a powerful gpu and/or want as many fps as possible.
