Intel's 12th Generation Alder Lake CPU Family - Goodbye 14nm, Hello 10nm!
The Intel Alder Lake-S Desktop CPU lineup will include the 12th Gen Core processors. Intel kicked off its lineup with the introductory 'K' and 'KF' chips which are now followed with more mainstream variants.
The architecture has seen several optimizations and key refinements that have led to an increase from 8 cores and 16 threads to 16 cores and 24 threads. The new 10nm ESF (Intel 7) process retains Intel's clock leadership, pushing the chips up to 5.2 GHz.
Intel’s Alder Lake will be built using the company’s new E and P cores, you can read the architectural deep dive over here, and represent a significant evolution in the company’s power efficiency targets. It will be built on the Intel 7 process and scale from 9 watts to 125 watts. DDR5 and PCIe gen5 will be supported (first to market) and feature new technologies like the Intel Thread Director.
Alder Lake will be fully scalable from Desktop (LGA1700) to ultra-mobile. Interestingly, however, while the platform has 8 P-cores and 8 E-cores, only the P-cores will support hyperthreading making for a total of 24 threads available. The integrated GPU will have 96 EUs of Xe architecture (good but nothing to write home about) but the thing that impressed us the most was the fact that Intel is claiming a 19% IPC uplift over Rocketlake – which should handily beat AMD parts if true.
Alder Lake will feature up to 30 MB of noninclusive LL Cache and support DDR5-4800, LP5-5200 along with DDR4-3200, and LP4x-4266. It will also support two times the PCIe bandwidth thanks to its support of PCIe 5 and will be able to provide up to 16 lanes of PCIe Gen5 with up to 64 GB/s. The new design is fully modular and built like lego and should be completely scalable and flexible. The compute fabric interconnect has a bandwidth of 1000 GB/s while the IO fabric has a BW of 64 GB/s. The memory subsystem supports up to 204 GB/s but more importantly can scale memory frequency (and power) according to the need of the SoC
Intel Non-K Alder Lake-S Core i9 CPUs
As expected, the Core i9 and Core i7 variants will retain the same core configuration as their 'K' series siblings. The main differences will come in the form of clock speeds and TDPs. Starting with the Core i9-12900(F), we are getting the same 16 core & 24 thread configuration with 30 MB of L3 cache. The clock speeds have been dialed back to 2.40 GHz base clock for the P-Cores and 1.80 GHz base clock for the E-Cores. The max boost clock will be pushed back by 100 MHz to 5.1 GHz. That has to be done to accommodate the lower 65W TDP versus the 125W (241 MTP) on the unlocked SKU.
Intel Non-K Alder Lake-S Core i7 CPUs
The Intel Core i7-12700(F) will also feature 12 cores, 20 threads, and 25 MB of L3 cache. The clock speeds are dialed back to a 2.10 GHz base for the P-Cores, a 1.60 GHz base for the E-Cores, and a max boost clock of 4.90 GHz on a 65W TDP. Next up, we have the Core i5 variants which see the most significant changes in the form of a non-hybrid design.
Intel Non-K Alder Lake-S Core i5 CPUs
The Intel Core i5-12600 and Core i5-12400, both will feature a 6 core and 12 thread design and will comprise only of Golden Cove (P-Cores). Both chips will feature 18 MB of L3 cache & clocks will be rated at 3.30 GHz and 3.00 GHz base & 4.8 GHz and 4.6 GHz boost, respectively. Both chips will come with 65W TDP and it will be very interesting to see how these chips fare against AMD's Ryzen 5 5600X as they are aiming at the same segment. There's also the Core i5-12500 which has been sandwiched between the two i5's and features the same core configuration but 2.5 GHz base & 4.4 GHz boost clocks.
Intel Non-K Alder Lake-S Core i3 CPUs
Lastly, we have the Core i3 lineup which includes the Intel Core i3-12300 and i3-12100. Both CPUs come with 4 cores and 8 threads (4 Golden Cove cores). The clocks are maintained at 4.4 GHz and 4.3 GHz boost for the chips respectively. They also pack 12 MB of L3 cache and every chip below the i5-12600 features the UHD730 graphics while the higher-end chips feature the UHD770 iGPU.
Intel Non-K Alder Lake-S Pentium/Celeron CPUs
There will also be a single Pentium and Celeron chip for now within the Alder Lake family. The Intel Pentium G7400 will feature 2 Golden Cove cores with 4 threads, a base clock of 3.7 GHz while the Celeron G6900 will feature the same config running at a lower clock speed of 3.4 GHz. The Pentium chip will rock 6 MB of cache while the Celeron will carry 4 MB of cache. Both feature UHD 771 iGPU and a base TDP of 46W.
