Intel Arc A570M vs Intel Arc A770 Comparison

The Intel Arc A770 and Intel Arc A570M represent two distinct tiers of Intel's Alchemist architecture, separated by both market positioning and physical hardware. The A770 is a desktop add-in card built on the full DG2-512 die, while the A570M is a mobile integrated graphics processor based on the cut-down DG2-256 die. While both share the same Xe-HPG architecture, their target platforms and performance envelopes are vastly different, with the desktop part holding a massive 87.5% lead in the only shared benchmark.

Architecture Differences

Both GPUs share the Xe-HPG architecture and are fabricated on TSMC's 6 nm process node, but they are built from fundamentally different silicon. The Arc A770 uses the DG2-512 chip with 21,700 million transistors on a 406 mm² die, achieving a transistor density of 53.4 million per square millimeter. The Arc A570M is built on the DG2-256 chip, which contains only 11,500 million transistors on a 269 mm² die, with a lower transistor density of 42.8 million per square millimeter. This means the A770 has nearly double the transistor count and a die that is roughly 51% larger.

The execution resources scale similarly. The A770 houses 4096 shading units, 256 texture mapping units, and 128 raster operation units. The A570M is exactly half of that in each category, with 2048 shading units, 128 TMUs, and 64 ROPs. Ray tracing hardware also scales in lockstep, with the A770 featuring 32 RT cores versus 16 RT cores on the A570M. Neither GPU has dedicated tensor cores, as the architecture relies on general-purpose shading units for compute workloads.

Clock speeds present a notable divergence. The A770 runs at a base clock of 2100 MHz and a boost clock of 2400 MHz, while the A570M operates at a substantially lower 900 MHz base and 1300 MHz boost. This clock speed difference is a major contributor to the performance gap, as the A770 benefits from both more hardware and higher operating frequencies. Memory clocks also differ, with the A770 running at 2000 MHz (16 Gbps effective) and the A570M at 1750 MHz (14 Gbps effective).

The bus interface is another differentiator. The A770 uses a full PCIe 4.0 x16 connection, while the A570M is limited to PCIe 4.0 x8. This reflects the mobile nature of the A570M, which is designed to be integrated into laptops and compact devices rather than slotted into a desktop motherboard.

Where Each One Wins

The Arc A770 is a clear winner in raw compute performance, but the A570M has distinct advantages in power efficiency and form factor. The A770's 225 W TDP and dual-slot design make it suitable for desktop gaming rigs and workstations where performance is the primary concern. Its 19.66 TFLOPS of FP32 compute and 512.0 GB/s of memory bandwidth allow it to handle demanding AAA games at high resolutions and compute-heavy workloads like rendering or machine learning inference.

The Arc A570M, with its 75 W TDP and IGP form factor, is designed for mobile platforms where thermal and power constraints are critical. Its 5.325 TFLOPS of FP32 performance and 224.0 GB/s of memory bandwidth are sufficient for 1080p gaming at medium settings and everyday productivity tasks. The A570M's integrated design means it takes up no PCIe slot space and requires no external power connectors, making it ideal for thin-and-light laptops where the A770 would be physically impossible to install.

The A770 wins the only direct benchmark comparison, but the A570M's advantage lies in its portability and efficiency. Users who need maximum performance in a desktop context should choose the A770, while those prioritizing battery life and a compact form factor will find the A570M more appropriate. The A570M is still active in production, whereas the A770 is end-of-life, which may matter for long-term availability and driver support.

Specification Differences

The two GPUs differ across nearly every major specification category. Memory size is a clear split: 16 GB on the A770 versus 8 GB on the A570M. Memory bandwidth follows suit, with the A770 delivering 512.0 GB/s against the A570M's 224.0 GB/s. The memory bus width is 256-bit on the desktop card and 128-bit on the mobile part.

Compute specifications show a similar pattern of halving. The A770 has 4096 shading units, 256 TMUs, and 128 ROPs, while the A570M has 2048 shading units, 128 TMUs, and 64 ROPs. Ray tracing cores are 32 versus 16. Pixel rate is 307.2 GPixel/s for the A770 and 83.20 GPixel/s for the A570M. Texture rate is 614.4 GTexel/s versus 166.4 GTexel/s. FP32 throughput is 19.66 TFLOPS against 5.325 TFLOPS, and FP16 is 39.32 TFLOPS versus 10.65 TFLOPS.

Clock speeds differ significantly. The A770 runs at 2100 MHz base and 2400 MHz boost, while the A570M is at 900 MHz base and 1300 MHz boost. Memory clocks are 2000 MHz (16 Gbps effective) on the A770 and 1750 MHz (14 Gbps effective) on the A570M.

Power and physical characteristics diverge completely. The A770 has a 225 W TDP, is dual-slot, requires 1x 6-pin and 1x 8-pin power connectors, and suggests a 550 W PSU. The A570M has a 75 W TDP, is an IGP, requires no power connectors, and has no suggested PSU. The A770 uses PCIe 4.0 x16, while the A570M uses PCIe 4.0 x8. Display outputs are also different: the A770 has 1x HDMI 2.1 and 3x DisplayPort 2.0, while the A570M's outputs are portable device dependent.

Production status and release dates differ. The A770 was released on October 11, 2022, and is end-of-life, with a successor named Battlemage. The A570M was released on July 31, 2023, and is still active, with no predecessor or successor listed. The A770 has a launch MSRP of 329 USD, while the A570M has no listed launch MSRP.

Head-to-Head Benchmarks

The only direct benchmark comparison available is Geekbench OpenCL, and the result is decisively in favor of the Intel Arc A770. The A770 scores 109,175 points, while the A570M scores 58,239 points. This represents an 87.5% advantage for the desktop card, a massive gap that underscores the fundamental difference in compute capability between the two.

The A770's score places it in the 90th percentile of all GPUs, with an average benchmark score of 68,809 across all tests. Its nearest rivals include the NVIDIA CMP 90HX at 69,000 points (0.3% lower), the AMD Radeon Instinct MI25 at 68,562 points (0.4% higher), the AMD Radeon Pro WX 8200 at 69,870 points (1.5% lower), and the NVIDIA Quadro P6000 at 69,986 points (1.7% lower). This indicates that the A770's OpenCL result is substantially above its average performance, driven by its high compute throughput and memory bandwidth.

The A570M's OpenCL score of 58,239 places it in the 88th percentile, with its average benchmark score also being 58,239 since only one test is available. Its nearest rivals are the AMD Radeon RX 6950 XT at 58,392 points (0.3% lower), the AMD Radeon RX 5600 OEM at 58,085 points (0.3% higher), the NVIDIA P102-100 at 58,528 points (0.5% lower), and the AMD Radeon PRO V710 at 58,657 points (0.7% lower). This tight grouping shows that the A570M sits in a competitive performance band, but it is nowhere near the A770's level.

The 87.5% delta in Geekbench OpenCL is a direct consequence of the hardware differences: the A770 has twice the shading units, more than twice the memory bandwidth, and significantly higher clock speeds. The A770's FP32 throughput of 19.66 TFLOPS is 3.7 times higher than the A570M's 5.325 TFLOPS, which explains why the OpenCL score gap is so pronounced. The A570M's lower clocks and reduced hardware resources simply cannot match the raw compute power of the desktop part, even though both share the same architecture and API support.
