Notes on 13 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 XT, Launch price: TechSpot reports AMD subsidizes this MSRP with a $50 retailer rebate, so street prices often run higher.
  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 XT, Boost clock: TechSpot's 2400 MHz figure is AMD's 'game' clock; the boost rating is 2970 MHz.
  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 XT, Power connectors: Corsair notes a few partner 90-series cards use 12V-2x6; the vast majority use 2x 8-pin.
  8. 8Intel Arc B570, Power connectors: Intel sells no first-party card; partner B570 cards use a single 8-pin connector.
  9. 9Intel Arc B570, PCIe lanes: Eight electrical lanes; Ars Technica notes Arc relies on Resizable BAR to perform optimally.
  10. 10AMD Radeon RX 9070 XT, DisplayPort version: TechPowerUp specifies the DisplayPort outputs as UHBR13.5.
  11. 11Intel Arc B570, DisplayPort version: Maker caps DisplayPort 2.1 at UHBR 13.5.
  12. 12Intel Arc B570, HDMI outputs: Intel sells no first-party B570; this is the standard partner-card port layout.
  13. 13Intel Arc B570, Hardware encode: Maker also lists 'H.265 (HEVC) Hardware Encode/Decode: Yes' and 'AV1 Encode/Decode: Yes'.

Performance and Architecture

The Radeon RX 9070 XT utilizes the Rdna 4 architecture with 4,096 shader cores and a boost clock of 2,970 MHz, delivering 48.7 TFLOPS of FP32 compute power. In contrast, the Arc B570 runs on the Xe2 architecture with 2,304 shader cores and a 2,500 MHz boost clock.

This gap means the AMD option handles demanding computational workloads much faster, while the Intel option suits basic gaming tasks.

Memory and Interface

The Radeon card features 16 GB of video memory across a 256-bit bus, yielding a bandwidth of 640 GB/s at 20 Gbps. The Intel card includes 10 GB of video memory on a 160-bit bus with 380 GB/s bandwidth at 19 Gbps.

Furthermore, the Radeon RX 9070 XT supports PCIe 5.0 across 16 lanes, whereas the Arc B570 uses PCIe 4.0 across 8 lanes and relies on Resizable BAR to perform optimally.

Power and Efficiency

The Radeon RX 9070 XT demands a board power of 304 W and requires a 750 W recommended PSU, utilizing an 8-pin connector setup. The Arc B570 keeps power consumption much lower at a board power of 150 W and uses a single 8-pin connector.

Buyers choosing the Intel card will need less robust power supplies and generate less heat inside the system.
