Notes on 14 values — test conditions and caveats
  1. 1Intel Arc B570, Release date: All three launch-day reviews are dated 16 Jan 2025; Intel's page gives only the quarter 'Q4'24.
  2. 2AMD Radeon RX 9070, Launch price: AMD's $549 starting MSRP at launch; AMD sells no reference card, so partner models may cost more.
  3. 3Intel Arc B570, Launch price: Launch MSRP; Ars Technica notes it only counts if you can actually get one at that price.
  4. 4Intel Arc B570, Shader cores: Derived per definition: 18 Xe-cores x 128 shading units = 2,304.
  5. 5AMD Radeon RX 9070, Boost clock: Peak 'up to' boost; AMD's game clock is 2070 MHz for typical gaming.
  6. 6Intel Arc B570, Boost clock: Intel publishes only a 'Graphics Clock'; per the key's definition it is recorded as the boost clock.
  7. 7AMD Radeon RX 9070, Board power: Partner overclocked cards can exceed 220 W; IGN measured 249 W peaks on a factory-OC card.
  8. 8AMD Radeon RX 9070, Power connectors: Two 8-pin PCIe power connectors are required (2x 8-pin per AMD and Sapphire).
  9. 9Intel Arc B570, Power connectors: Intel sells no first-party card; partner B570 cards use a single 8-pin connector.
  10. 10Intel Arc B570, PCIe lanes: Eight electrical lanes; Ars Technica notes Arc relies on Resizable BAR to perform optimally.
  11. 11AMD Radeon RX 9070, DisplayPort version: Club386 lists the DP 2.1a link rate as UHBR13.5; UHBR20 is not supported.
  12. 12Intel Arc B570, DisplayPort version: Maker caps DisplayPort 2.1 at UHBR 13.5.
  13. 13Intel Arc B570, HDMI outputs: Intel sells no first-party B570; this is the standard partner-card port layout.
  14. 14Intel Arc B570, Hardware encode: Maker also lists 'H.265 (HEVC) Hardware Encode/Decode: Yes' and 'AV1 Encode/Decode: Yes'.

Performance and Compute

The AMD card delivers 36.1 TFLOPS of FP32 compute power backed by 3,584 shader cores. This gives it a heavy advantage in demanding games and render workloads compared to the Intel competitor, which features 2,304 cores.

Boost clocks reach 2,520 MHz on the AMD option and 2,500 MHz on the Intel option. Both GPUs keep base clocks unpublished.

Memory and Bandwidth

The AMD option features 16 GB of Gddr6 video memory running on a 256-bit bus, delivering 640 GB/s of memory bandwidth at 20 Gbps. It also includes 64 MB of last-level cache.

The Intel option includes 10 GB of Gddr6 memory on a narrower 160-bit bus, achieving 380 GB/s of bandwidth at 19 Gbps.

Power and System Requirements

The AMD card demands a board power of 220 W and a 650 W recommended PSU, requiring two 8-pin power connectors. Partner overclocked cards can exceed this power draw.

The Intel card operates at a lower 150 W board power and relies on a single 8-pin connector.

Connectivity and Display

The AMD GPU supports PCIe 5.0 across 16 lanes for maximum data throughput. It also features HDMI 2.1b and DisplayPort 2.1a ports.

The Intel GPU runs on PCIe 4.0 across 8 lanes and requires Resizable BAR to perform optimally. Partner cards for the Intel option typically provide one HDMI 2.1 port and three DisplayPort 2.1 ports.
