AMD Radeon RX 6600 XT vs Intel Arc A370M Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive performance gap between these two GPUs. In the two shared benchmark tests, the AMD Radeon RX 6600 XT wins every round, and it does so by an enormous margin. On the Geekbench OpenCL test, the AMD card scores 80,503 points against the Intel Arc A370M's 29,676 points. That is a 63.1% deficit for the Intel part, meaning the AMD GPU delivers roughly 2.7 times the compute throughput in this workload. The Vulkan result is closer in relative terms but still lopsided: AMD scores 72,417 versus Intel's 28,673, a 60.4% gap. For context, the Intel part's average benchmark score across all recorded tests is 29,175, while the AMD card averages 24,442. The raw scores tell the story: the RX 6600 XT is in a different performance class entirely.

The Intel Arc A370M does hold a notable position in the overall database percentile ranking. It sits at the 74th percentile of all GPUs, which is actually 4 percentage points higher than the RX 6600 XT's 70th percentile. This is a quirk of the database's ranking methodology, as the Intel mobile chip benefits from being compared against a wider field that includes lower-end integrated and mobile parts. The AMD card's nearest rivals include the NVIDIA GeForce GTX 1630 (0.7% ahead), the Intel Arc A350M (0.8% behind), the NVIDIA GeForce GTX 780 Ti (0.8% ahead), and the NVIDIA GeForce RTX 2080 SUPER (1.1% ahead). The Intel A370M's nearest rivals are all within 1% of its average score: the AMD Radeon RX Vega M GH at 0.1% behind, the AMD FirePro W8000 at 0.1% behind, the AMD Radeon RX 470 at 0.6% ahead, and the AMD Radeon RX 6800M at 1% ahead. This tells you that the A370M competes with older desktop mid-range cards and mobile Vega parts, while the RX 6600 XT sits near much stronger desktop GPUs like the RTX 2080 SUPER.

Architecture Differences

The two GPUs come from completely different design philosophies. Intel's Arc A370M uses the Xe-HPG architecture on a 6 nm TSMC process, built around the DG2-128 chip. The die measures 157 mm² and packs 7,200 million transistors, giving it a transistor density of 45.9 million per square millimeter. AMD's RX 6600 XT uses the RDNA 2.0 architecture on a 7 nm TSMC process with the Navi 23 chip. That die is 237 mm² and contains 11,060 million transistors, for a density of 46.7 million per square millimeter. The AMD chip is physically larger and has more transistors, but the density is nearly identical; the manufacturing process differences are visible in the fact that Intel achieves similar density on a smaller die.

The compute resources differ dramatically. The Intel A370M has 1,024 shading units, 64 texture mapping units, 32 ROPs, and 8 ray tracing cores. The AMD RX 6600 XT doubles nearly everything: 2,048 shading units, 128 TMUs, 64 ROPs, and 32 ray tracing cores. This doubling is reflected in the raw throughput numbers. Intel's FP32 compute is rated at 4.198 TFLOPS and FP16 at 8.397 TFLOPS (2:1 ratio). AMD's FP32 reaches 10.60 TFLOPS and FP16 hits 21.21 TFLOPS, also at a 2:1 ratio. The pixel fill rate tells the same story: 65.60 GPixel/s for Intel versus 165.7 GPixel/s for AMD. Texture rate is 131.2 GTexel/s versus 331.4 GTexel/s.

Memory architecture is another major split. The Intel A370M uses 4 GB of GDDR6 on a 64-bit bus, producing 112.0 GB/s of bandwidth. The RX 6600 XT has 8 GB of GDDR6 on a 128-bit bus, yielding 256.0 GB/s. The AMD card has double the capacity and more than double the bandwidth. Clock speeds also favor AMD: the A370M runs at 1550 MHz base and 2050 MHz boost, while the RX 6600 XT runs at 1968 MHz base, 2359 MHz game clock, and 2589 MHz boost. The effective memory speed is 14 Gbps for Intel and 16 Gbps for AMD. Both support PCIe 4.0 x8, the same DirectX 12 Ultimate (12_2) feature level, OpenGL 4.6, and Vulkan 1.4. Neither part lists tensor cores.

The Verdict

The data points in one direction: for raw performance, the AMD Radeon RX 6600 XT is the clear choice. It wins both head-to-head benchmarks decisively, has more than double the shading units, TMUs, ROPs, and ray tracing cores, and provides twice the memory capacity with more than twice the bandwidth. A 63.1% lead in OpenCL and a 60.4% lead in Vulkan are not small margins; they represent a fundamental class difference. The RX 6600 XT also has a higher base clock, boost clock, and game clock, along with higher FP32 and FP16 throughput. If the workload is compute-heavy or graphics-bound, the AMD card is the only sensible pick.

The Intel Arc A370M does have the higher percentile rank at 74 versus 70, and it draws far less power at 35 W versus 160 W. It also uses a smaller die (157 mm² versus 237 mm²) with fewer transistors (7,200 million versus 11,060 million). Those are not performance advantages, but they matter in specific contexts. The A370M is an integrated-class mobile part (slot width is listed as IGP) with no power connectors, while the RX 6600 XT is a dual-slot card with a single 8-pin connector and a suggested PSU of 450 W. The Intel part is end-of-life, as is the AMD part, but the A370M released on 2022-03-29 while the RX 6600 XT launched on 2021-07-29.

For a desktop builder, the RX 6600 XT is the only reasonable option if performance is the goal. The launch MSRP of the RX 6600 XT is 379 USD. For a thin-and-light laptop or an integrated system where the 35 W power envelope and IGP form factor are requirements, the A370M is the only one that fits. The data does not show any scenario where the Intel part outperforms the AMD part; it simply occupies a lower power tier.

Where Each One Wins

The AMD Radeon RX 6600 XT wins every performance metric that matters for gaming and compute workloads. It has double the pixel rate, double the texture rate, more than double the FP32 throughput, and more than double the FP16 throughput. The 256.0 GB/s memory bandwidth versus 112.0 GB/s means the AMD card can feed its wider compute pipeline without stalling. The 8 GB frame buffer versus 4 GB gives it room for higher-resolution textures and larger datasets. In any benchmark that stresses the GPU, the RX 6600 XT is the winner by margins that cannot be recovered by drivers or tuning.

The Intel Arc A370M wins in the power and form-factor categories. At 35 W TDP, it uses less than a quarter of the RX 6600 XT's 160 W. The A370M is an IGP-class part with no external power connector, making it suitable for systems where a discrete card cannot fit. It has a smaller die and fewer transistors, which is not an advantage in itself but does indicate lower manufacturing complexity. The A370M also holds a higher database percentile at 74 versus 70, which reflects its placement relative to the broader GPU population. For a user who needs a GPU in a compact or low-power mobile system, the A370M is the only one of these two that fits the bill. For everyone else, the RX 6600 XT is the clear pick based on the recorded benchmark data.
