SiSoftware Releases Intel Arc Alchemist A380 Video Card Benchmark Results
The company behind the SiSoftware benchmarks has shared new potential details of Intel’s upcoming Arc Alchemist graphics cards. Among other things, the company shows possible OpenCL benchmark results from a low-position Arc A380 video card.
SiSoftware writes on its website that Intel will come up with three Arc Alchemist series. Intel would introduce an A300 series with low-ranking graphics cards, an A500 series with midrange cards and an A700 series with flagships. That is consistent with previous rumours. The series differ in the number of execution units and the memory arrangements.
The website also writes that the video cards are produced at 7nm at TSMC, but that is not correct. Intel has previously confirmed that the video cards will be produced on TSMC’s 6nm process, although that is in fact an advanced version of TSMC’s 7nm node. The video cards also support DirectX 12 Ultimate and will include matrix engines for deep learning. Fp64 support would be missing.

| Series | Arc A300 | Arc A500 | Arc A700 |
| Execution units | 128 | 384 | 512 |
| shaders | 1024 | 3072 | 4096 |
| Memory | 6GB GDDR6 | 12GB GDDR6 | 16GB GDDR6 |
| Memory bus | 96bit* | 192bit | 256bit |
| Memory Speed | 14Gbit/s* | 16Gbit/s | 16Gbit/s |
| Memory bandwidth | 192GB/s* | 384GB/s | 512GB/s |
*Based on the message from SiSoftware. 96bit and 14Gbit/s actually provide a bandwidth of converted 164GB/s.
Intel Arc A380 benchmarks
Furthermore, SiSoftware publishes some benchmark results of an Intel Arc A380 desktop video card, which previously appeared in drivers. That video card is in the A300 series with lower-positioned GPUs. The SiSoftware benchmarks include testing OpenCL performance. In it, for example, the video card performs comparable to the Nvidia GeForce GTX 1660 Ti and the performance is close to that of AMD’s Radeon RX 6500 XT and the Nvidia GeForce RTX 3050, depending on the test. However, the company does not share which platform or drivers were used for the tests.
SiSoftware also goes into memory bandwidth, which is higher than the Radeon RX 6500 XT bandwidth, but lower than that of the GeForce RTX 3050 and GTX 1660 Ti. In AES cryptography, the A380 is considerably slower than the other video cards. SiSoftware further tests workloads for financial and scientific analysis.
It is not known exactly when the Arc A380 video card will be released. Intel introduces Arc Alchemist graphics cards for laptops and desktops. Those video card series will appear in the first and second quarters of this year, respectively. Workstation models appear ‘by the third quarter’. The video cards will receive support for ray tracing and Intel XeSS, a counterpart to AMD FSR and Nvidia DLSS.
