AMD Radeon RX 7900M vs Intel Arc A770 Comparison

# AMD Radeon RX 7900M vs Intel Arc A770

The benchmark database places the AMD Radeon RX 7900M at the 94th percentile of all GPUs, while the Intel Arc A770 sits at the 90th percentile. The RX 7900M records an average benchmark score of 97,487, which puts it 4.3% behind the NVIDIA Quadro RTX 6000 and 0.4% ahead of the AMD Radeon Pro VII. The Arc A770’s average score of 68,809 places it 0.3% behind the NVIDIA CMP 90HX and 0.4% ahead of the AMD Radeon Instinct MI25. The head-to-head data is unambiguous: the RX 7900M wins all three recorded comparisons, with margins ranging from 18.6% to 68.4%.

Head-to-Head Benchmarks

The largest single gap appears in the Geekbench Vulkan test. The RX 7900M scores 158,760 points, while the Arc A770 manages 94,284 points. That is a delta of 68.4%, meaning the AMD part delivers roughly two-thirds more performance in this API workload. This is the widest margin in the entire comparison, and it indicates a substantial advantage in Vulkan compute or rendering scenarios. The data shows the RX 7900M’s Vulkan result is also its strongest individual benchmark relative to its own average, while the Arc A770’s Vulkan score is its weakest of the three recorded tests.

The 3DMark Steel Nomad DX12 test shows a 41.5% advantage for the RX 7900M. The AMD card scores 4,201 points, while the Intel card scores 2,969 points. This is a modern DirectX 12 workload, and the margin here is more than a third of the Intel card’s own score. For context, the Arc A770’s nearest rivals in the database, such as the NVIDIA CMP 90HX, sit within 1.7% of its average score, so the 41.5% gap in this test is far larger than the typical separation between adjacent GPUs in the rankings.

The smallest head-to-head margin is in Geekbench OpenCL, where the RX 7900M scores 129,499 against the Arc A770’s 109,175. That is an 18.6% delta. While still a decisive win for AMD, this is the closest the Intel card comes to matching its competitor. OpenCL is often a more balanced cross-vendor workload, and the data reflects that here: the gap narrows but does not disappear. The RX 7900M’s OpenCL score is, in fact, lower than its Vulkan score, while the Arc A770’s OpenCL score is higher than its Vulkan score, suggesting the Intel architecture performs relatively better in OpenCL than in Vulkan.

Across all three tests, the RX 7900M records a perfect 3-0 win tally. The average margin across the three benchmarks is roughly 42.8%, but the individual results vary widely: from 18.6% in OpenCL to 68.4% in Vulkan. This spread suggests the AMD card’s advantage is not uniform across APIs, and the choice of workload significantly affects the observed delta.

The Verdict

The data points to a clear overall winner: the AMD Radeon RX 7900M outperforms the Intel Arc A770 in every recorded benchmark. The smallest margin, 18.6% in OpenCL, is still a decisive victory. The largest margin, 68.4% in Vulkan, is a near-doubling of performance. Anyone selecting between these two strictly on benchmark results should choose the RX 7900M, provided the platform supports it.

However, the verdict is not purely about raw speed. The RX 7900M is an integrated graphics processor (IGP) with no power connectors and no discrete slot width, meaning it is designed for a laptop or mobile chassis. The Arc A770 is a dual-slot add-in card requiring a 6-pin and an 8-pin power connector and a 550 W suggested power supply. The RX 7900M consumes 180 W, while the Arc A770 consumes 225 W. The AMD part achieves its higher performance at a lower power draw, which is notable but not surprising given the different market positions.

The Arc A770’s production status is end-of-life, with the successor listed as Battlemage. The RX 7900M is still active in production. For system builders looking at new hardware, the AMD card is the current product, while the Intel card is a previous generation. The release dates support this: the Arc A770 launched in October 2022, and the RX 7900M launched in October 2023. The RX 7900M’s predecessor is Polaris Mobile, while the Arc A770’s predecessor is Xe Graphics, indicating different lineage paths.

Where Each One Wins

The AMD Radeon RX 7900M wins in all three recorded benchmark categories. In 3DMark Steel Nomad DX12, it leads by 41.5%, which is the second-largest margin. This test likely stresses traditional rasterization and DirectX 12 features, and the RX 7900M’s higher pixel rate and texture rate align with that interpretation. The RX 7900M has a pixel rate of 401.3 GPixel/s versus 307.2 GPixel/s for the Arc A770, and a texture rate of 601.9 GTexel/s versus 614.4 GTexel/s. Interestingly, the Intel card has a slightly higher texture rate, yet it loses the 3DMark test by a wide margin, suggesting that other factors dominate in that workload.

In Geekbench OpenCL, the RX 7900M wins by 18.6%. This is the closest result, and it may reflect the Arc A770’s relatively stronger compute scheduling or driver optimization for OpenCL. The RX 7900M still wins, but the margin is the smallest of the three. For users who primarily run OpenCL workloads, the Intel card is less disadvantaged than in other APIs.

In Geekbench Vulkan, the RX 7900M wins by 68.4%. This is the largest margin, and it suggests a significant architectural advantage for AMD in Vulkan. The RX 7900M’s ray tracing cores number 72 versus 32 for the Arc A770, and while Vulkan is not exclusively a ray tracing workload, the higher RT core count may contribute to the gap. The data shows that Vulkan is where the AMD card pulls away most decisively.

Architecture Differences

The RX 7900M is built on the RDNA 3.0 architecture with the Navi 31 chip, codenamed Plum Bonito. It uses a 5 nm process at TSMC and packs 57,700 million transistors on a 529 mm² die, resulting in a transistor density of 109.1M per mm². The Arc A770 uses the Xe-HPG architecture with the DG2-512 chip, built on a 6 nm process at TSMC. It contains 21,700 million transistors on a 406 mm² die, with a density of 53.4M per mm². The RX 7900M has more than double the transistor count, and its density is roughly double that of the Intel part.

The RX 7900M features 4,608 shading units, 288 texture mapping units, and 192 raster output units. The Arc A770 has 4,096 shading units, 256 TMUs, and 128 ROPs. The AMD card leads in shading units and ROPs, while the texture unit counts are close. The RX 7900M has 72 ray tracing cores, while the Arc A770 has 32, a 40-core difference that likely explains part of the Vulkan gap. Neither card has tensor cores listed in the database.

Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API compatibility is identical. The RX 7900M is an integrated processor with no slot width and no power connectors, designed for portable devices. The Arc A770 is a dual-slot card with two power connectors and a 550 W suggested PSU, designed for desktop installation. The display outputs differ: the RX 7900M’s outputs are portable device dependent, while the Arc A770 offers 1x HDMI 2.1 and 3x DisplayPort 2.0.

Specification Differences

The clock speeds differ notably. The RX 7900M has a base clock of 1825 MHz and a boost clock of 2090 MHz, while the Arc A770 has a higher base of 2100 MHz and a boost of 2400 MHz. The Intel card runs faster, but the AMD card achieves higher performance despite lower clocks, likely due to architectural efficiency and the higher transistor budget. Memory clocks are 2250 MHz (18 Gbps effective) for the RX 7900M and 2000 MHz (16 Gbps effective) for the Arc A770, giving the AMD card its 576.0 GB/s bandwidth advantage.

The compute rates are not close. The RX 7900M delivers 38.52 TFLOPS of FP32 and 77.05 TFLOPS of FP16 (2:1), while the Arc A770 delivers 19.66 TFLOPS of FP32 and 39.32 TFLOPS of FP16 (2:1). The AMD card offers nearly double the compute throughput. Pixel rates are 401.3 GPixel/s for the RX 7900M versus 307.2 GPixel/s for the Arc A770, and texture rates are 601.9 GTexel/s versus 614.4 GTexel/s, a rare instance where the Intel card leads slightly.

The bus interface is PCIe 4.0 x16 for both. The RX 7900M was released on October 18, 2023, and remains active.
