AMD Radeon RX 7700 vs Intel Arc B370 Comparison

Head-to-Head Benchmarks

The database contains one directly comparable benchmark between the AMD Radeon RX 7700 and the Intel Arc B370: 3DMark Steel Nomad DX12. In this test, the AMD Radeon RX 7700 scores 2865 points, while the Intel Arc B370 scores 1184 points. The delta is 142% in favor of the AMD part, meaning the RX 7700 more than doubles the Arc B370's output in this specific workload.

Looking at the broader benchmark context, the AMD Radeon RX 7700's average benchmark score across all recorded tests is 15852, while the Intel Arc B370's average is 1184. That difference is stark, but the RX 7700 also has a much larger benchmark sample: nine recorded tests versus a single test for the Arc B370. The single Steel Nomad result for the Arc B370 aligns closely with its nearest rivals in the database, which include the ATI Mobility Radeon HD 5570 (avg score 1186, delta -0.2%), ATI Radeon HD 5770 (avg score 1190, delta -0.5%), AMD Radeon HD 7650M (avg score 1192, delta -0.7%), and AMD FirePro M2000 (avg score 1168, delta +1.4%). The Arc B370 sits within 1.4% of all four of those older parts, indicating that its performance tier is firmly in legacy mobile graphics territory.

The RX 7700's nearest rivals, by contrast, are substantially faster. The AMD Radeon R9 370X averages 15862 (delta -0.1% from the RX 7700), the AMD Radeon RX 9060 averages 16014 (delta -1%), the AMD Radeon Pro W5500 averages 15679 (delta +1.1%), and the NVIDIA GeForce RTX 3060 Ti averages 16129 (delta -1.7%). The RX 7700's average score of 15852 places it in a completely different performance class from the Arc B370, with the gap between the two being larger than the gap between the RX 7700 and any of its own nearest rivals.

The percentile rankings reinforce this separation. The RX 7700 sits at the 58th percentile among all GPUs in the database, meaning it outperforms more than half of all recorded graphics cards. The Arc B370 sits at the 5th percentile, which places it among the slowest entries in the database. In the single head-to-head test, the RX 7700 wins 1 of 1 comparisons, and the Arc B370 wins 0.

Where Each One Wins

The AMD Radeon RX 7700 wins in every benchmark category where both have data. In 3DMark Steel Nomad DX12, the RX 7700's 2865 score versus the Arc B370's 1184 represents a 142% advantage. This is the only shared test, so the win tally is 1 for AMD and 0 for Intel.

For the RX 7700, the broader benchmark suite shows strengths across different API generations. Its PassMark G3D score is 20974, its PassMark GPU Compute score is 10963, and its Geekbench OpenCL score is 106028. The RX 7700 also records PassMark scores for DirectX 9 (261), DirectX 10 (92), DirectX 11 (186), DirectX 12 (96), and G2D (1206). These results indicate the RX 7700 handles both legacy and modern graphics workloads, with the G3D and compute scores being particularly strong relative to its percentile position.

The Intel Arc B370 has no data outside the Steel Nomad test, so the database cannot confirm any workload where it outperforms the RX 7700. Its single recorded score of 1184 in Steel Nomad places it alongside the ATI Mobility Radeon HD 5570 and ATI Radeon HD 5770, both of which are decades-old parts. The Arc B370's 5th percentile ranking means the data shows no scenario in which it wins against the RX 7700.

The use-case split is therefore one-sided. For DirectX 12 gaming workloads, the RX 7700 dominates. For compute tasks, the RX 7700's PassMark GPU Compute score of 10963 indicates substantial parallel processing capability, though the Arc B370 has no compute benchmark to compare. The RX 7700's memory configuration, 16 GB of GDDR6 on a 256-bit bus with 624.1 GB/s bandwidth, supports its high fill rates. The Arc B370 uses system shared memory with system-dependent bandwidth, which the database lists as a fundamental limitation for memory-intensive tasks.

Architecture Differences

The AMD Radeon RX 7700 uses the Navi 32 chip built on RDNA 3.0 architecture, fabricated by TSMC on a 5 nm process. It contains 28,100 million transistors on a 346 mm² die, giving a transistor density of 81.2M per mm². The Intel Arc B370 uses the Panther Lake chip built on Xe3-LPG architecture, fabricated by Intel on a 3 nm process. The database lists the Arc B370's transistor count and die size as unknown, and its density as null, so no direct comparison of those figures is possible.

The RX 7700 has 2560 shading units, 160 texture mapping units, and 96 raster operation units. It also includes 40 ray tracing cores. The Arc B370 has 1280 shading units, 40 TMUs, and 20 ROPs, with 10 ray tracing cores. The RX 7700 therefore has double the shading units, four times the TMUs, and nearly five times the ROPs of the Arc B370. The ray tracing core count is four times higher on the AMD part.

Clock speeds differ significantly. The RX 7700 has a base clock of 1900 MHz, a boost clock of 2459 MHz, and a game clock of 2041 MHz. Its memory runs at 2438 MHz, which the database lists as 19.5 Gbps effective. The Arc B370 has a base clock of 300 MHz and a boost clock of 2400 MHz, with no game clock listed. The Arc B370's memory is system shared, so no dedicated memory clock exists. The RX 7700's boost clock is only 2.5% higher than the Arc B370's, but the base clock is more than six times higher.

The memory systems are fundamentally different. The RX 7700 has 16 GB of dedicated GDDR6 memory on a 256-bit bus, delivering 624.1 GB/s of bandwidth. The Arc B370 has system shared memory with system-dependent bandwidth, meaning its performance scales with the host system's memory configuration rather than a fixed specification. This explains the massive gap in pixel rate: the RX 7700 achieves 236.1 GPixel/s, while the Arc B370 achieves 48.00 GPixel/s. Texture rates are 393.4 GTexel/s for the RX 7700 versus 96.00 GTexel/s for the Arc B370.

Compute throughput also diverges. The RX 7700 delivers 25.18 TFLOPS for both FP32 and FP16 at a 1:1 ratio. The Arc B370 delivers 6.144 TFLOPS for FP32 and 12.29 TFLOPS for FP16 at a 2:1 ratio. The RX 7700 is roughly four times faster in FP32, and the FP16 ratios indicate different design priorities: the AMD part handles FP16 at full rate, while the Intel part halves its FP32 rate to achieve FP16.

Power and physical design differ completely. The RX 7700 has a TDP of 200 W, requires two 8-pin power connectors, and a suggested 550 W power supply. It is a dual-slot card measuring 267 mm in length, 135 mm in height, and 50 mm in width. The Arc B370 has a TDP of 25 W, uses no power connectors, has no suggested PSU, and is an integrated graphics processor (IGP) with no physical dimensions listed. The RX 7700 uses a PCIe 4.0 x16 bus interface, while the Arc B370 uses an IGP bus interface.

Both parts support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Display outputs differ: the RX 7700 has 1x HDMI 2.1a, 2x DisplayPort 2.1, and 1x USB Type-C, while the Arc B370's display outputs are listed as portable device dependent.

The Verdict

The recorded data shows a decisive performance gap. The AMD Radeon RX 7700 wins the only shared benchmark by 142%, holds a 58th percentile ranking among all GPUs, and averages 15852 across nine tests. The Intel Arc B370 scores 1184 in its single test, sits at the 5th percentile, and its nearest rivals are all ATI and AMD parts from the HD 5000 and HD 7000 era.

The RX 7700 is designed as a discrete, high-throughput graphics card. Its 16 GB of dedicated GDDR6 memory, 624.1 GB/s bandwidth, 2560 shading units, and 25.18 TFLOPS FP32 performance place it in a class where it competes with the NVIDIA GeForce RTX 3060 Ti, which averages 16129 (delta -1.7% from the RX 7700). The RX 7700's 200 W TDP and dual-slot footprint are consistent with a performance-oriented add-in board.

The Arc B370 is an integrated GPU with a 25 W TDP. Its 1280 shading units, 6.144 TFLOPS FP32, and system shared memory target low-power mobile or portable devices. The 300 MHz base clock suggests aggressive power saving, while the 2400 MHz boost clock shows it can reach higher frequencies when needed. However, even at boost, the architecture's limited ROP count (20) and texture units (40) constrain its output to 48 GPixel/s and 96 GTexel/s.

For any workload measured in the database, the RX 7700 is the clear choice. The Arc B370's only advantage is power efficiency, with an 87.5% lower TDP (25 W versus 200 W), but no benchmark data exists to quantify the performance-per-watt tradeoff. The Arc B370's release date of January 26, 2026, comes after the RX 7700's September 17, 2025 release, yet the newer part is substantially slower in the recorded Steel Nomad test.
