Intel’s initial batch of Xe-HPG (high-performance gaming) DG2 graphics cards will reportedly comprise six models. This is according to a puzzle decoded by hardware enthusiast and occasional leaker harukaze5719, which lists six variants and their purported specifications. Intel’s flagship Xe-HPG DG2 GPU will supposedly leverage 512 Execution Units (4,096 Streaming Processors) and 8 or 16 GB of GDDR6 memory, while the bottom end will be occupied with a model featuring 96 Execution Units (768 Streaming Processors) and 4 GB of GDDR6 memory.
- 512 EU (4096 SP) / 256bit-bus / 8 or 16G VRAM
- 384 EU (3072 SP) / 192bit-bus / 6 or 12G VRAM
- 256 EU (2048 SP) / 128bit-bus / 4 or 8G VRAM
- 192 EU (1536 SP) / 128bit-bus / 4G VRAM
- 128 EU (1024 SP) / 64bit-bus / 4G VRAM
- 96 EU (768 SP) / 64bit-bus / 4G VRAM
The purported specifications suggest that Intel’s flagship Xe-HPG DG2 graphics card might be able to go toe to toe with AMD’s Radeon RX 6800 XT (4,608 SP, 16 GB GDDR6), which has already proven its mettle against NVIDIA’s GeForce RTX 3080 (8,704 SP, 10 GB GDDR6X). Rumors suggest that Intel’s DG2 GPUs will be manufactured on TSMC’s 7-nanometer process.
“Intel introduced a new Xe microarchitecture variant, Xe-HPG, a gaming-optimized microarchitecture, combining good performance-per-watt building blocks from Xe-LP, leveraging the scale from Xe-HP for a bigger configuration and compute frequency optimization from Xe-HPC,” a fact sheet reads. “A new memory subsystem based on GDDR6 is added to improve performance per dollar and XeHPG will have accelerated ray tracing support. Xe-HPG is expected to start shipping in 2021.”
