Intel Arc A570M vs Intel Arc G3 Comparison

Intel Arc A570M and Intel Arc G3 represent two distinct approaches within Intel’s graphics lineup. The A570M is a discrete mobile GPU built on the Xe-HPG architecture, while the G3 is an integrated solution based on Xe3-LPG, designed for Panther Lake processors. The recorded data shows that these two parts have very different performance profiles, power envelopes, and intended use cases. This analysis walks through the benchmark results, architectural differences, and specification gaps.

Head-to-Head Benchmarks

The database contains a single benchmark result for the Intel Arc A570M. In the Geekbench OpenCL test, the A570M scores 58,239 points. This places it at the 88th percentile among all GPUs tracked in the database. The Arc G3, by contrast, has no recorded benchmark scores. Its average benchmark score is listed as zero, and its percentile ranking sits at 50. Because there are no head-to-head benchmark entries and no wins recorded for either part, direct numeric comparison is limited to the A570M’s single score and the G3’s absence of data.

The A570M’s score of 58,239 becomes more meaningful when viewed against its nearest rivals. The AMD Radeon RX 6950 XT averages 58,392 points, which is 0.3% higher than the A570M. The NVIDIA P102-100 averages 58,528 points, 0.5% higher. The AMD Radeon PRO V710 averages 58,657 points, 0.7% higher. The AMD Radeon RX 5600 OEM averages 58,085 points, which is 0.3% lower than the A570M. These deltas are all within a single percentage point, indicating that the A570M sits in a tightly clustered performance band around these desktop and workstation parts, despite being a mobile discrete GPU.

For the Arc G3, the absence of benchmark data means no comparable figures exist. The database records no OpenCL score, no rival comparisons, and no wins. Its percentile rank of 50 is the only positioning metric available, and that rank is based on an average score of zero, which suggests it has not yet been measured or is too new for inclusion. Any performance inference for the G3 must come from its clock speeds, shader count, and memory configuration, not from direct measurement.

Where Each One Wins

The Intel Arc A570M wins in every category where data exists. It has a recorded benchmark score, a percentile rank of 88, and a set of nearest rivals that place it near the top of the database. The Arc G3 has no wins because it has no recorded scores. In practical terms, the A570M is the only one of the two that can be positioned against other GPUs using measured data.

The A570M also wins on raw throughput metrics. Its FP32 performance is 5.325 TFLOPS, and its FP16 performance is 10.65 TFLOPS at a 2:1 ratio. It delivers a pixel rate of 83.20 GPixel/s and a texture rate of 166.4 GTexel/s. The G3 counters with higher peak FP32 at 6.144 TFLOPS and FP16 at 12.29 TFLOPS, but its pixel rate is 48.00 GPixel/s and its texture rate is 96.00 GTexel/s. So the G3 has a theoretical compute advantage in floating-point work, but the A570M has a clear advantage in pixel and texture throughput.

For memory-bound tasks, the A570M wins decisively. It has 8 GB of dedicated GDDR6 memory on a 128-bit bus, with 224.0 GB/s of bandwidth. The G3 uses system shared memory, with bandwidth listed as system dependent. Shared memory is typically slower and contends with the CPU for access, so the A570M’s dedicated memory gives it a structural advantage in workloads that depend on bandwidth.

The G3 wins in power efficiency. Its TDP is 25 W, compared to 75 W for the A570M. That is a 3x difference in power draw, and the G3 achieves its higher FP32 figure within that lower envelope. For systems where power is the limiting factor, such as thin-and-light laptops, the G3 is the more practical choice.

Architecture Differences

The two GPUs come from different architectural generations and are built on different process nodes. The Intel Arc A570M uses the DG2-256 chip based on the Xe-HPG architecture, from the Alchemist generation, specifically the Arc 5 Mobile variant. It is fabricated on a 6 nm process at TSMC. The chip contains 11,500 million transistors on a die size of 269 mm², giving a transistor density of 42.8 million transistors per square millimeter.

The Intel Arc G3 uses the Panther Lake chip based on the Xe3-LPG architecture, from the Arc Graphics-M (Panther Lake) generation. It is fabricated on a 3 nm process at Intel. Transistor count and die size are listed as unknown, and transistor density is not recorded. The G3 is a newer design by process generation, but the A570M is a larger, more complex chip.

Shader resources differ significantly. The A570M has 2048 shading units, 128 TMUs, 64 ROPs, and 16 ray tracing cores. The G3 has 1280 shading units, 40 TMUs, 20 ROPs, and 10 ray tracing cores. The A570M has 60% more shading units, 220% more TMUs, 220% more ROPs, and 60% more ray tracing cores than the G3. These ratios explain why the A570M dominates pixel and texture throughput despite having a lower boost clock.

Clock speeds are reversed in favor of the G3. The A570M has a base clock of 900 MHz and a boost clock of 1300 MHz. The G3 has a base clock of 300 MHz and a boost clock of 2400 MHz. The G3’s boost clock is 84.6% higher than the A570M’s boost clock, and its FP32 advantage reflects that higher frequency, though it is partially offset by the lower shader count.

Both GPUs support the same API set: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Both are listed with IGP slot width, though the A570M uses a PCIe 4.0 x8 bus interface while the G3 is IGP-only, meaning it connects through the processor rather than a discrete PCIe slot. Both have display outputs listed as portable device dependent.

Memory architecture is fundamentally different. The A570M uses 8 GB of GDDR6 on a 128-bit bus with 224.0 GB/s bandwidth, and a memory clock of 1750 MHz with 14 Gbps effective speed. The G3 uses system shared memory, with no dedicated VRAM, no dedicated bus width, and bandwidth dependent on the host system. This affects not only capacity but also latency and contention.

The Verdict

The data supports a clear split. The Intel Arc A570M is the stronger performer in measured benchmarks and in memory-bound and rasterization-heavy workloads. Its 88th percentile ranking, its single OpenCL score of 58,239, and its dedicated 8 GB GDDR6 pool at 224.0 GB/s make it a discrete-class solution despite its mobile designation. It also has more TMUs, more ROPs, and more ray tracing cores, which gives it a structural edge in pixel and texture work.

The Intel Arc G3 is the more efficient part. Its 25 W TDP is one third of the A570M’s 75 W, and it still reaches 6.144 TFLOPS FP32 and 12.29 TFLOPS FP16. For systems that cannot accommodate a discrete GPU, such as ultraportable designs based on Panther Lake, the G3 provides a usable integrated graphics path with the same API support as the A570M. Its lack of benchmark data means its practical performance remains unverified in the database.

For users who need measured performance and dedicated graphics memory, the A570M is the only choice with recorded evidence. For users who prioritize low power draw and are constrained to an integrated GPU, the G3 offers higher theoretical compute and a much newer process node, but no measured scores to confirm real-world behavior.

The specification table highlights the trade-offs. The A570M pairs more execution resources with slower clocks and dedicated memory. The G3 pairs fewer execution resources with a much higher boost clock and shared memory. Both support DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, so software compatibility is identical. The A570M is the only one with measured performance data, and it holds the top percentile rank. The G3 remains an unmeasured, low-power integrated option whose performance is not yet established in the database.
