More Intel ARC B580 Details Leak

Intel ARC Battlemage B580 leak reveals PCIe 5.0 support and more

More details for Intel’s upcoming ARC B580 GPU have leaked, thanks to Videocardz. Thanks to an early listing on Amazon, two Intel Battlemage GPU models from ASRock were revealed. These GPUs have revealed a lot of information about the Intel ARX B580, revealing some key upgrades.

For starters, the GPU reportedly uses PCIe 5.0 connectivity through a PCIe x8 slot, which gives it the same bandwidth as a PCIe 4.0 x16 connector. Note that GPUs like the RTX 4060 and RTX 4060 Ti use a PCIe 4.0 x8 connector. This gives the B580 access to more PCIe bandwidth on compatible systems. That said, this bandwidth is unlikely to be necessary to maximise gaming performance.

It has also been reported that the ASRock ARC B580 Steel Legend has a GPU clock speed of 2.8 GHz. That’s 700 MHz faster than Intel’s ARC A770, their last-generation flagship. While ASRock’s GPU is an overclocked model, a 700 MHz boost should help Intel deliver huge generational performance gains. Remember, Intel’s new Xe2 graphics architecture should enable performance gains though higher clock speeds and architectural improvements.

ARC B580 TDP Speculation

The ASRock B580 Steel Legend uses two PCIe 8-pin connectors for power. In contrast, the ASRock B580 Challenger only uses a single 8-pin power connector. Intel has opted to stick to standard PCIe power connectors with its new GPUs. It is likely that no Intel ARC B-series GPU will use a 12VHPWR or 12V-2×6 connector.

Power-wise, the ASRock B580 Challenger’s design suggests that the GPU has a TDP of under 225W. After all, a PCIe slot can only deliver up to 75W of power, and a PCIe 8-pin connector is only rated for 150W of power delivery. As such, this GPU’s TDP cannot be over 225W. The ARC B580 Steel Legend model may have a higher maximum power limit, as it has two 8-pin PCIe power connections.

Finally, Intel’s ARC B580 appears to use 12GB of GDDR6 memory. This memory is clocked at 19 Gbps. This gives the B580 4GB more memory than its predecessor, the A580, but less overall bandwidth. This is a non-issue, as the B580 had the same memory bandwidth as an A770, making its memory bandwidth specifications overkill. Overall, having more memory is more important than having more memory bandwidth for this SKU. A lot of modern games can struggle to run on 8GB GPUs, making GPUs with larger frame buffers preferable.
