Intel's 12th-gen Alder Lake-S CPU appears in database

In a nutshell: Intel's 12th-gen Alder Lake chips are some way off—we still have Rocket Lake's arrival in a few months—but benchmarks for one of the desktop hybrid CPUs have just been discovered.

Prolific hardware leaker @Tum_Apisak found the Alder Lake-S results on the SiSoft Sandra benchmarking database. It lists a chip that features 16 cores and 32 threads, though the software sometimes detects it as 16 cores and 24 threads in certain benchmarks. There's also 30MB of L3 cache and 10x 1.25MB L2.

It's expected that this Alder Lake-S chip is made up of eight Golden Cove cores (big) and eight Gracemont cores (little), similar to Arm's big.LITTLE design, combining eight high-powered cores with eight energy-efficient ones.

Elsewhere, the chip is listed with a clock speed of 1.4 GHz, likely for the Gracemont cores. The iGPU has 256 shader cores at 1.15 GHz and will almost certainly be Intel's Xe LP graphics engine, which we saw running Battlefield V at 30fps on a laptop without a dedicated graphics card earlier this year.

We've heard that Alder Lake-S, which is expected to be built on the 10nm SuperFin process, uses the PCIe 4.0 interface, and the Sabrent Rocket 4.0 NVMe it's paired with here suggests this will be the case. It's also said to support PCIe 5.0, so we can expect to see some blistering fast drives in the future, and it may be Intel's first consumer processors to support DDR5, which has just seen its first modules launched by SK Hynix.

Leaked Intel documents from earlier this year claim that Alder Lake will abandon the LGA 1200 socket launched with Comet Lake (also set for use in Rocket Lake) in favor of the LGA 1700 socket. In addition to the 500 extra pins, it's rumored to be a rectangular shape (45mm × 37.5mm) rather than the usual square.

As for the SiSoft Sandra results, we do see Alder Lake-S beat the Ryzen 5 3600 in some benchmarks, though we shouldn’t read too much into these right now.

It BETTER be able to beat the Ryzen 5 3600, or Intel is in huge trouble... By the time Alder Lake comes out, AMD will be at the next generation (5600 we assume) and will be even faster...

Plus, this was a 16 core CPU - it better be able to beat a 6 core offering!

Intel is still in the "catch up" mode but needs to accelerate their program if they home to catch or pass AMD. The competition is good but I'd like to see more of an even comparison / capability between the comparable chip sets. But honestly, unless you are doing comparisons for the sake of doing so, these things are close and AMD still maintains the edge with cost differences .....

How much longer before these high-core count CPU's have base clock speeds in the MHz?

Why doesn't intel take out the igpu of their cpus and design one with more cache or cores so it can compete better with amd?. For example the i9-9900k the igpu is almost one third of the die, they could use that space for cores or cache like amd does with their ryzen cpus.

A really dumb move if Intel release's 12th gen without DDR5 from the start. I am not waiting for DDR5 from Intel another year.

This won't be out much before Zen 4 IMO, 2022 is more likely than 2021. Still it will be interesting to see how it works on PC. I see AMD has patents for similar Big.Little architecture too.

It is being tested at 1.38 GHz. At full speed it will be 3.5x faster.
 
That’s not how clock speed works... it will be faster - it not 3x faster!

Lol...that is how clock speed works, IPC is fixed to the clock speed for a particular architecture. In actual application benchmarks that can translate differently because there are other factors at play but a 5 GHz processor is 3.5x faster than a 1.38 GHz processor.
