Chinese CPU is competitive with modern Intel ones
- Thread starter Zarax
- Start date
Fairly unsurprising, but pretty much if you start with a very similar product to Zen 1 and are able to implement some of the changes AMD made to keep it competitive over the years, that even a Chinese derivative will be somewhat competitive.
What is the performance like of "clean slate" Chinese CPUs?
Yes it’s a multi core design. Make sure you buy more than a single core for the best experience.
It’s interesting that updating the IO and adding DDR5 support to Zen 1/1.5 has brought the performance upto Intel.
A large factor there is core count - the V-Ray numbers show that core for core it is roughly the same as Intel's Gracemont E cores - a hypothetical 16 E core / 32 thread CPU would score about the same.
An all Atom part would struggle in its current implementation. The Atom’s MESH architecture would need a lot of attention without links to the Skylake ringbus and cache. MESH is arguably more interesting than Ringbus but it’s seriously dated now.
The existing Raptor Lake bus architecture would choke but that is another story really and more relevant to things like having good gaming performance.
Intel could have done this themselves instead of releasing the 13/14th gen on us..
Ah, so you know an all Intel e core chip wouldn’t perform as you implied. You’re an odd one….

I specifically said hypothetical as E cores with hyper-threading don't exist. But the bus would hold up for the performance requirements of 16x E cores in multi-threading (the existing implementation is clusters of 4 each having just the one ring stop) and still give performance similar to the single threaded performance of this CPU - the issues with the bus come into play more with the higher performing P cores and latency requirements of things like gaming.
This Hygon CPU won't come even close to existing Intel CPUs for things like gaming.

I’m sure in your dreams Intel have completely reworked its Atom core and this post make sense, but back in reality the chip you describe will struggle against these chips.
What I'm describing is pretty much exactly what these chips are - one way of approaching it is 2x Gracemont cores on a ring stop in this context is essentially the same as having 2x CCDs with IF.
Can see for yourself here the performance of just 8x E cores (the implementation on Raptor Lake is slightly better) despite being in clusters without their own ring stop:
Intel Core i9-12900K E-Cores Only Performance Review
With Alder Lake, Intel is betting big on hybrid CPU core configurations. The Core i9-12900K has eight P(erformance) cores and eight E(fficient) cores. We were curious and tested the processor running the E-Cores only to see how well they perform against architectures like Zen 2, Zen 3, Skylake...

Theyre just making an AMD CPU under license so it's not really a competitor, just a Chinese fab making old AMD CPUs.

Yeah, I actually know exactly how Intels Atom e cores perform on their Xeon platform. Anyway here are Intels e cores and accompanying p cores getting a hard time from a chinesium generation 1/1.5 Zen part.

I actually love this stuff, Same with the Chinese GPUs which perform quite badly but i find it exciting and would love to get my hands on them to play around with.
That Hygon C86-4G does have a rather low Clockspeed at 2.8Ghz...i wonder if they can be overclocked.

Crestmont and the Xeon bus is a different ball game - but core fore core, thread for thread, this "chinesium" is only approximately the performance of theoretical Gracemont era E cores with SMT/HT and is only competitive in certain multi-threaded loading against the Raptor Lake CPUs due to brute force number of cores and threads. If you paired one up with a GPU like a 4090 for gaming you'd be crying even at 4K it would be a huge bottleneck.
Do the maths it is 22% slower with 16 cores / 32 threads in V-Ray than the 8+12 core / 28 thread 14700.

Yes, it's an AMD derivative like all Chinese X86 CPUs, however there will be independent evolution just like mobile SOCs so I wouldn't underestimate it.
