VIA Zhaoxin x86 4 and 8-core SoC processors launch
As we talked about a while ago, VIA launches their Zhaoxin processors, well SoC's really. Zhaoxin has launched the new processors in the KX-5000 series. With the to be released KX-7000, it wants to compete with AMD again.
KaiXian
KX is short for KaiXian, the 5000 series is to be used in laptops and desktops. The KaiXian chips are fabbed on a 28nm process from Chinese HLMC, using a WuDaoKou microarchitecture. The procs are quad-cores up to 2.0 GHz with 8 cores versions as well at the same maximum speed.
The KaiXian 5000 series is mostly aimed forPCs, workstations, and laptops. Those SKUs are positioned against Intel’s Core i3 and Core i5 processors.
| New SKUs | |||
|---|---|---|---|
| Model | Cores/Threads | Frequency | L2 Cache |
| KX-5640 | 4/4 | 2.0 GHz | 4 MiB |
| KX-5540 | 4/4 | 1.8 GHz | 4 MiB |
| KX-U5680 | 8/8 | 2.0 GHz | 8 MiB |
| KX-U5580 | 8/8 | 1.8 GHz | 8 MiB |
| KX-U5580M | 8/8 | ≤ 1.8 GHz | 8 MiB |
The fastest 8-core proc thus has eight cores and eight threads at 2.0 GHz based on a 187 mm2 64-bit chip that has 2.1 billion transistors. 64 kb L1 cache is present per core and a total of 8 MB L2 cache. Instructions include Intel VT-x, Trusted Execution Technology, SSE4.2, AVX, and AVX2. The chips have PCIe 3.0, a total of 16 lanes and then four lanes likely for an additional interconnect to a chipset or heck, even something M2. The integrated memory controller supports dual channel ddr4-2133 up-to 64 GB. The integrated GPU provides a maximum of 4096 x 2304 pixels at 60 Hz via display port or HDMI. This is a DirectX 11.1 part, not DX12.
KaisHeng 20000
Zhaoxin also announced the KaisHeng 20000 series which is geared towards embedded networking, storage, and servers. This series should not be confused with a similarly named “ZX-2000” series which are actually quad-core ARM Cortex-A17 CPUs.
| New SKUs | |||
|---|---|---|---|
| Model | Cores/Threads | Frequency | L2 Cache |
| KH-26800 | 8/8 | 2.0 GHz | 8 MiB |
| KH-25800 | 8/8 | 1.8 GHz | 8 MiB |
As with the KX-5000 parts, all models have virtualization support compatible with Intel’s VT-x, Trusted Execution Technology (TXT), SSE 4.2, and AVX support. The KaisHeng 20000 parts support up to 128 GiB of memory and have added support for ECC and RDIMMs. Additionally, those SKUs do not have a GPU enabled. Zhaoxin reported the following SPEC CPU 2006 scores:
| SPEC CPU 2006 Scores | |||
|---|---|---|---|
| Test | KX-5640 (4C @ 2GHz) | KX-U5680 (8C @ 2GHz) | Atom C2750 (8C @ 2.4GHz/2.6GHz) |
| SPECint | 19.1 | 19.9 | 17.5 |
| SPECint_rate | 64.3 | 115 | 101 |
| SPECfp | 22.9 | 25.7 | 23.0 |
| SPECfp_rate | 53 | 81.3 | 76.8 |

No more, latest Amiga OS can run more modern hardware... but it's no more an Amiga.
Yes and there is a big market about those kind of inexpensive and silent hardware (laptop and desktop) and few competitor, it's a nice move to try out if they can do better and earn money with it.
They don't need reverse engineering, they have left Intel with everything clear, and they have still their licence X86 / X86-64.
Off topic but Amiga OS (4 onwards) require a PowerPC based setup. They tried to sell there own desktops based on Power PC but they were hideously expensive for the spec and limited usability.

At 2.0ghz, they're not going to be competitive against anything AMD or Intel currently have. Maybe they want to compete with the Celeron J1800 and Athlon 5350?

Well hey, everyone started somewhere. I hope they will mature faster, as I'm 200% certain the have a fantastic reverse engineering team.

Of course VIA's socket and chipset, don't expect that it will work in either AMD or Intel mobo. That kind of compatibility hasn't been seen since OG Pentium

28nm @2.0Ghz.
Bro, they're dead at start.

VIA has done well with low-power processors. They've never produced a mid-range or high-end processor that was able to compete directly with their AMD or Intel counterparts though.
Atoms. IIRC it should be expected to have around 55~60% of intel-Core IPC, that's just bit better than Atoms which are around 50%.
With 2GHz it is quite comparable. Except here, you have 4 or 8 cores. While new Atoms are fake HT chips. One thread causes 50% load on 4 core CPU, 2 Threads extract all CPU performance, and adding 3rd is for nothing.
I expect them to be efficient in similar way as Atoms. 2 fully loaded threads in Atom x5-z8500 ate 9.6W.
Considering better IPC, if 8C chip runs at 40W, it is better than Atom.
If they were able to clock it to 4GHz, it would be only as good as 8C Bulldozer against old i5 w/ 4C. Except today 6C and 8C chips are common. So, it would need to have 12C or 16C.
Since that's not the case, it can compete only with Atoms.
