Specifications of the Intel Tiger Lake-H Core i9-11980HK have come to light indicating 200 MHz higher base and 300 MHz lower boost clocks compared to its predecessor, the Core i9-10980HK. The leaked specs also indicate that the Core i9-11980HK may potentially offer improved AVX-512 performance when the TDP is configured up to 65 W.
We just reported on information about a handful of upcoming Intel Tiger Lake-H processors viz. the Core i9-11900H, Core i7-11800H, and the Core i5-11400H. Now, we are getting to know the clock speeds and TDP info about what could be the flagship 11th gen mobile H-series processor, the Core i9-11980HK, along with some possible boost information and TDPs for the other mentioned SKUs while running AVX-512 workloads.
This information comes via tipster @OneRaichu and is summarized below.
|SKU||Cores / Threads||Base / Boost Clock (GHz)||All-core Boost (GHz)||TDP (W)||AVX-512 Clock (GHz)||cTDP (W)|
|Core i5 (?) -11260H||6 / 6||2.6 / 4.4||4.0||45||2.1||35 (Down)|
|Core i5-11400H||6 / 12||2.7 / 4.5||4.1||45||2.2||35 (Down)|
|Core i7-11800H||8 / 16||2.4 / 4.6||4.2||45||2.0||35 (Down)|
|Core i9-11900H||8 / 16||2.5 / 4.9||4.4||45||2.1||35 (Down)|
|Core i9-11980HK||8 / 16||2.6 / 5.0||4.5||45||3.3||65 (Up)|
Interestingly, the Core i9-11980HK seems to have a 200 MHz higher base clock but a 300 MHz lower boost than its predecessor, the Core i9-10980HK. The transition to 10 nm Enhanced SuperFin can somewhat offset the lower boost, but we will have to wait for benchmarks to fully ascertain that.
@OneRaichu also posted AVX-512 clocks. Here, the Core i9-11980HK offers a 200 MHz higher frequency at 3.3 GHz compared to the 3.1 GHz seen with the Core i9-10980HK, which is not an AVX-512 chip. Intel seems to continue to advocate for AVX-512 ever since it was introduced on the client side with Ice Lake’s Sunny Cove architecture despite consternation from respected quarters. However, as we’ve seen in Anandtech‘s early review of the Core i7-11700K Rocket Lake-S desktop CPU, AVX-512 demands higher power draws and frequency downclocking.
Since the Core i9-11980HK is an unlocked processor, it can have a up to a 65 W cTDP-up to accommodate AVX-512 at a decent 3.3 GHz frequency (it is not yet clear how many active cores clock at 3.3 GHz while running AVX-512). The rest of the lineup including the Core i9-11900H, Core i7-11800H, Core i5-11400H, and Core i5 (?) -11260H downclock significantly below the base clock and run at 35 W cTDP-down in order to process AVX-512 instructions.
@OneRaichu further adds that the Core i7 and Core i9 variants support DDR4-3200 while the Core i5 SKUs are compatible with DDR4-2933 and feature 2 MB L3 cache per core.
We expect Intel to announce Tiger Lake-H some time during the middle of Q2 this year, so the above information must be taken with a pinch of salt till then. That being said, these initial specs don’t seem too bad, and we may see good competition between Intel and AMD in the enthusiast laptop space in the months ahead.
