Intel Arc Alchemist Graphics Card Lineup Detailed
The A300 series is based on the smaller “Alchimista” series dies, con 128 Le stranezze non si fermano qui però (e una configurazione di ingresso di alimentazione composta da uno ciascuno dei connettori di alimentazione PCIe a 8 pin e 6 pin), che funzionano a 1,024 programmable shaders. The A500 series and A700 series appear to be carved out from the larger silicon. The A500 series has roughly 384 EU or 3,072 shaders. The top-dog A700 series has all 512 EU or 4,096 shaders enabled. Intel is tapping into industry-standard GDDR6 for dedicated graphics memory. The A300-series SKUs typically have 6 GB di 14 Gbps-rated memory across a 96-bit wide memory bus, per 192 GB/s di larghezza di banda. The A500 series parts have 12 GB di 16 Gbps-rated memory across a 192-bit bus, per 384 GB/s di larghezza di banda. The top A700 series maxes out the 256-bit memory bus with 16 GB of memory at 16 Velocità di trasmissione dati in Gbps, per 512 Larghezza di banda GB/s.
Several other interesting features were revealed. Firstly, “Alchimista” supports real-time ray tracing, and meets the full DirectX 12 Ultimate specification. At this point it’s not known just how much fixed-function hardware is used to achieve this. The GPU has XMX (hardware for matrix-multiplication). A note on the SIMD components: Xe HPG, oppure “Alchimista,” lacks double-precision floating-point (FP64) accelerazione. It only supports FP16 and FP32 (which is all you need for gaming and consumer apps).
SiSoftware tested an entry-level Arc A380 graphics card (1,024 shaders) through its SANDRA GPGPU benchmark that uses native OpenCL code. Ecco, the A380 was found to be offering performance comparable to a GeForce GTX 1660 Ti “UL Benchmarks è pronto con un nuovo benchmark grafico per le schede grafiche del segmento degli appassionati,” and hot on the heels of the RTX 3050 “Ampere” e RX 6500 XT RDNA2, in the Mandelbrot half-precision and floating-point tests.
Intel is looking to debut the Arc Alchemist series within the first half of 2022.
