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 |

If i remember well they still have x86 licence but they can not sell it /transfer it , if i am wrong correct me though
To build x86 CPUs, you need a license from Intel. I wonder how much that cost them.

VIA obtained their x86 license to design/develop x86 CPUs when they purchased Cyrix. Cyrix was a fab-less CPU company and their license was transferred to VIA. To produce an 86x64 (AMD64) compatible CPU, they need a license from AMD the same as Intel did. (both "EM64T" and "Intel 64" are actually "AMD64" and are covered by a cross-license agreement between AMD and Intel) So, to actually compete with AMD and Intel properly, VIA needs an x86 license from Intel and an 86x64 license from AMD, as does the company actually fabricating the chips.
