Chinese CPU might match Zen3 IPC

Loongson Begins to Enable CPUs That Could Rival AMD and Intel Offerings

Loongson's posted the first Linux patches for its LS 3A6000-series processors

Take this with a spoon of salt of course and also consider that Longsoon has a 14nm node at best so it does not mean it will match Zen3 performance.
That said, chinese companies are trying to circumvent node limitations by heavily investing in chiplets and heterogeneous architecture, which means they might find a way to get similar capabilities in a more distributed system (maybe not for gaming but it's not their focus TBH) at the likely price of higher system power consumption.

In the short term this means very little for consumers, in a few years we might see something cost effective emerge though. Imagine What you expect from a CPU or a GPU split between several components, maybe at 2x the current power consumption but at half the price and with the promise of more modular upgrade capabilities, would you go for it?

How many of these articles about the upcoming Chinese/Russian CPU/GPU that are going to match Intel/AMD/Nvidia do we see every year?

I'll believe them when I actually see a product and independent reviews.

Zhaoxin/Longsoon is one of the very few players that had at least one product reviewed in western press (spoiler: it wasn't competitive), which is why I consider them interesting.

This is a Zen 3 CPU, just made under license. In principle yeah I’d buy a Zen CPU made under licence no problem, but buying from a Chinese firm is rather more topical.

It’s interesting, but if not vastly different from the 5000, I can’t see it getting anywhere near to Intel or AMD.

Loongson’s 3A5000: China’s Best Shot?

We at Chips and Cheese have covered two Chinese CPU architectures: Zhaoxin’s x86 compatible Lujiazui architecture found in the KX-6000 series of CPUs and Phytium’s ARM compatible FT663 architecture found in the D2000 series of CPUs. Zhaoxin was founded in 2013 as a joint venture between VIA and...

Honestly I don't expect them to get anything better than Zen1 performance, if that.
The point of China is making something that they can be self sufficient with, even if it means being 5 years behind.

if its priced cheapo enough even id be interested in it. 64 core cpu with zen3 level ipc for £150ish yep im in.

You say that like it doesn't happen with stuff made for Western markets. The NSA and GCHQ make heavy use of it (see: Snowden files), and it won't be the first time CCP have been found meddling with hardware destined for Western sources. Intel ME and AMD PSP are literal chips on chips with their own (Minix) OS and are a total hardware backdoor into any system, operating well outside 'your' system and giving full root capabilities, just like an IPMI. Don't tell me that doesn't get a tickle when some three letter agency or other fancies...

Apparently this is not even x86/ARM/RISC-V, they're using their own instruction set called "LoongArch", software support is going to be small, and trying to do a direct comparison to other CPUs is going to be hard.

Even if IPC is Zen 3 level their previous CPUs had rather low clocks and more power usage compared to Intel/AMD, so I don't expect overall performance to even be close.

Like I said, Zen 1 equivalent at best.

Zen 3 was the same as 6th gen intel in core benchmarks(games) so i don't really think the chinese are much of a threat just yet.

Its bad....

Loongson’s 3A5000 is the most promising domestic Chinese CPU we’ve seen so far. Compared to the Zhaoxin KX-6640MA and Phytium D2000, Loongson’s 3A5000 is a wide core with a better balanced backend and a better cache hierarchy. But it suffers the same fundamental issues as the other two in its quest to be a general purpose CPU. Loongson’s LA464 simply cannot deliver performance in the same class as any recent Intel or AMD architecture. Compared to its western counterparts, LA464’s architecture is smaller, the L2 and L3 caches are worse, and the DDR4 memory controller is embarrassingly bad. Even though Loongson has gotten their cores up from 1 GHz to 2.5 GHz, no one runs desktop or even laptop CPUs at clocks that low. Because of its massive clock speed deficiency, Loongson can’t even get in to the same performance ballpark as recent desktop CPUs. It even struggles against Neoverse N1 running at 3 GHz.

No Zen 3 is way beyond that, the 5800X was faster in games than the 10900K, often a lot faster....

Search through these where the GPU bottleneck has been removed. https://www.anandtech.com/show/1621...-review-5950x-5900x-5800x-and-5700x-tested/18

10'th Gen IPC was similar to Zen 1+.
Zen 2 IPC a bit higher.
Zen 3 IPC quite a chunk higher.

Zen 3 was awesome. It still holds its own, i have a 5800X too.

That’s not a fair tell tale for IPC between architecture.

They should have been clocked to the lowest base clock of all the cpu instead of the boost clock

There are node advantages to the later fab processes also

Constant clock at a level that these products typically run is definitely a fair way to compare IPC in the same x86 architecture, sure, it would have been better to count the number of instructions while doing a wide range of tasks (e.g. a full SPEC benchmark) rather than a Cinebench, but it's giving you a rough picture.

in games the amd 3XXX chips matched the intel 6XXX, say 3600 vs 6700k

i made an error i thought zen3 was 3000 chips

They all have a different base clock, do you even know what IPC is?
