Russian-Chinese Irtysh 32-core CPU runs The Witcher 3 at 30+ FPS — heavyweight chip still imposes CPU bottleneck despite impressive specs
Irtysh processors may not be the first chips that come to mind when you think of the best CPUs. These chips cater to the Russian market and are relatively unknown internationally. Recently, the YouTube channel PRO Hi-Tech demonstrated the Irtysh C632’s gaming performance by running The Witcher 3: Wild Hunt alongside a Radeon RX 9060 XT. The results are nothing to brag about, though, since the 32-core processor is still leagues behind mainstream processors.
While the Irtysh processors are marketed as a Russian technological achievement, they actually leverage the LoongArch instruction set architecture (ISA) developed by Chinese chipmaker Loongson. As a result of U.S. sanctions that have directly cut Russia off from acquiring x86 CPUs, the country has sought alternative solutions, and the Irtysh chips from the Russian microelectronics firm Springboard Electronics are one of them.
Springboard Electronics, a subsidiary of Tramplin Electronics, appears to have licensed Loongson’s IP for the Irtysh series to circumvent U.S. restrictions. Many believe that the Irtysh chips are simply rebranded variants of the Loongson server-graded 3C6000 chips, which feature a chiplet design. Russia's transition comes with challenges, as LoongArch lacks software compatibility and performance optimizations, so it's still lagging behind mature x86 and Arm ecosystems. Despite these limitations, the Irtysh is an important milestone for Russia as the country attempts to build an independent technological infrastructure.

Processor | Loongson Equivalent | Cores / Threads | Clock Speed (GHz) | L3 Cache (MB) | TDP (W) |
|---|---|---|---|---|---|
Irtysh C664 | 3C6000/Q | 64 / 128 | 2.0 | 128 | 250 - 300 |
Irtysh C632 | 3C6000/D | 32 / 64 | 2.1 | 64 | 180 - 200 |
Irtysh C616 | 3C6000/S | 16 / 32 | 2.2 | 32 | 100 - 120 |
The Irtysh series, which currently includes models such as the C664, C632, and C616, leverages Loongson's LA664 execution cores, which are marketed as offering performance parity with AMD’s Zen 3 and Intel’s Ice Lake architectures. In terms of features, the Irtysh processors mirror the Loongson 3C6000, supporting up to 64 PCIe 4.0 lanes and quad-channel DDR4-3200 memory.
When Loongson introduced the LoongArch LA664 architecture in 2023, the company announced its intention to make the IP accessible to partners to drive broader adoption beyond China. This move opened the door for companies like Springboard Electronics to license the LoongArch LA664 architecture and further customize it to its own requirements.
It has allowed the Russian firm to incorporate features tailored to the Russian market, such as a domestically manufactured security module. The approach is consistent with Loongson’s practices. The 3C6000 processors also come with a range of security features for the Chinese market, including a dedicated security module and support for national cryptographic algorithms.
For its gaming demonstration, the Irtysh C632 processor was running The Witcher 3: Wild Hunt with a Radeon RX 9060 XT. The system achieved frame rates ranging from 22 to 32 FPS on ultra settings and from 25 to 38 FPS on low settings. These results, which PRO Hi-Tech provided, lacked important details such as the exact resolution and whether the original or next-gen version of the game was used. Based on the image's quality, the gameplay appears to have been recorded at 1080p (1920x1080).

The results were lackluster and evidently show a substantial processor bottleneck. The switch from low to ultra image settings did little to increase performance. Although not the fastest graphics card around, the Radeon RX 9600 XT, when coupled with a capable processor, can comfortably deliver over 100 FPS in The Witcher 3: Wild Hunt with low settings at 1080p.
One of the most significant limitations of the LoongArch LA664 platform is its lack of compatibility with x86 operating systems, such as Windows. It leaves Linux as the primary and only viable operating system for Loongson, or in this case, Irtysh processors. Running games like The Witcher 3: Wild Hunt implicates multiple layers of compatibility and translation. To get the game to run on the Irtysh C632, it likely required a combination of Box64 and Steam Proton or Wine. Each layer adds performance overhead.
Due to U.S. sanctions, Russia can't legally procure high-performance (or any-performance) x86 processors from Intel or AMD. That doesn't mean Russia has to start from scratch, though, since it can piggyback on what China has already achieved, such as Loongson's chip development.

Kindaian Speed and power indicate that they are based on older transistor densities. So it's natural the low performance. But it is an interesting development all in all.Reply
We will have to wait for the dust to settle before making any kind of positive conclusions from it. For now is... neutral... -

Also, just to be fair, games aren't made to efficiently run on 32 cores.Kindaian said:Speed and power indicate that they are based on older transistor densities. So it's natural the low performance. But it is an interesting development all in all.

xiq Some thoughts:Reply
The naming convention is nice at least, C616 for the 16 core one, C632 for the 32 core one, etc, straight to the point.
The gaming capabilities of the CPU are lacking, but that's basically the worst test you can give such a thing. i want to look up benchmarks for how it performs in video editing or home server types of tasks.
So basically these are just Chinese chips with a Russian label on them, except for the "russian security module" and I don't really know what that is. -

It's never going to be as fast as Chinese LoongArch CPUs, though. China will always have the fastest LA chips.Kindaian said:Speed and power indicate that they are based on older transistor densities. So it's natural the low performance. But it is an interesting development all in all.
The way I look at these is similar to how ZhaoXin licensed first-gen EPYC IP from AMD and added their own encryption block to it. By the time they shipped, AMD was already onto second gen Epyc, at least.
If you're interested in LoongArch CPUs and how they perform, just look upstream to what Loongson, itself, is doing.Kindaian said:We will have to wait for the dust to settle before making any kind of positive conclusions from it. For now is... neutral... -

Typo. If you check the link, it goes to the RX 9060 XT.SILVERTHRONE32 said:"9600XT"??? -
pug_s This is not even an x86 cpu, so running some game in an emulator would lower the performance.Reply -
usertests This is stuck at 2.1 GHz. The newer 3B7000 can supposedly do 3.5 GHz, 67% higher.Reply
Get one of these near 4 GHz with other improvements, and maybe 60 FPS in those games is viable. -
justrudi Ummm... Youtube is supposed to be blocked by the russian state and even have direct consequences for avoiding the blockade. It is just surprising this media have not dies yet and have not moved to a rutube...Reply
