AMD Radeon RX 7700S vs Intel Arc B370 Comparison

AMD Radeon RX 7700S and Intel Arc B370 occupy very different positions in the mobile graphics landscape, with the recorded benchmark data showing a decisive performance gap between them. The RX 7700S, part of the Radeon RX 7000 series, is a dedicated mobile GPU built on the Navi 33 chip with RDNA 3.0 architecture. The Arc B370, from Intel’s Arc Graphics-M (Panther Lake) family, uses the Xe3-LPG architecture on a 3 nm process and relies on system-shared memory. Their benchmark profiles, architectural designs, and target use cases are fundamentally distinct.

Where Each One Wins

The AMD Radeon RX 7700S wins the only directly comparable benchmark in the database, the 3DMark Steel Nomad DX12 test, with a score of 2185 against the Intel Arc B370’s 1184. That is an 84.5% advantage for the AMD part. This single result places the RX 7700S at the 78th percentile among all GPUs, while the Arc B370 sits at the 5th percentile. The RX 7700S also has additional recorded benchmarks that the Arc B370 lacks: a Geekbench OpenCL score of 62983 and a Geekbench Vulkan score of 36380. These results indicate that the AMD GPU delivers substantially higher compute throughput in both OpenCL and Vulkan workloads.

The Intel Arc B370 has no benchmark wins in the head-to-head comparison. Its only recorded score, the 3DMark Steel Nomad DX12 result of 1184, places it near the bottom of the database. Its nearest rivals, according to the recorded data, include the ATI Mobility Radeon HD 5570 (average score 1186, a 0.2% difference), the ATI Radeon HD 5770 (1190, 0.5% difference), and the AMD Radeon HD 7650M (1192, 0.7% difference). These are older, lower-performance parts, which shows that the Arc B370’s measured performance aligns with legacy mobile and desktop GPUs from over a decade ago.

For practical use cases, the RX 7700S is suited for gaming and compute tasks that demand dedicated graphics memory and high throughput. The Arc B370, with its 25 W power envelope and system-shared memory, appears oriented toward low-power, integrated-style functionality, likely for thin-and-light portable devices. The data shows a clear split: the RX 7700S wins in raw performance and feature-rich workloads, while the Arc B370 offers a much lower power draw, but at a significant performance cost.

Architecture Differences

The two GPUs diverge sharply in their underlying designs. The AMD Radeon RX 7700S uses the Navi 33 chip, built on TSMC’s 6 nm process, with 13,300 million transistors on a 204 mm² die. This yields a transistor density of 65.2 million transistors per square millimeter. The architecture is RDNA 3.0, with a codename of Hotpink Bonefish, and it belongs to the Navi Mobile (RX 7000M) generation. It has 2048 shading units, 128 texture mapping units, 64 raster operation units, and 32 ray tracing cores. The Intel Arc B370, in contrast, uses the Panther Lake chip with Xe3-LPG architecture, fabricated on Intel’s 3 nm process. Its transistor count and die size are listed as unknown, and it has no codename. Its generation is Arc Graphics-M (Panther Lake).

In terms of compute resources, the RX 7700S has 2048 shading units versus the Arc B370’s 1280, a 60% higher count. The RX 7700S also has 128 TMUs and 64 ROPs, compared to 40 TMUs and 20 ROPs on the Arc B370. Ray tracing cores are 32 on the AMD part versus 10 on the Intel part. The AMD GPU’s pixel rate is 160.0 GPixel/s and its texture rate is 320.0 GTexel/s. The Arc B370’s pixel rate is 48.00 GPixel/s and texture rate is 96.00 GTexel/s. These differences directly explain the large benchmark gap.

Memory architecture is another major divergence. The RX 7700S has 8 GB of dedicated GDDR6 memory on a 128-bit bus, with a bandwidth of 288.0 GB/s and a memory clock of 2250 MHz (18 Gbps effective). The Arc B370 uses system-shared memory, with its type, bus width, and bandwidth all listed as system-dependent. This means the Intel GPU has no dedicated video memory and must share system RAM, which typically limits bandwidth and latency compared to a dedicated memory subsystem.

Clock speeds also differ. The RX 7700S base clock is 1500 MHz, with a boost clock of 2500 MHz and a game clock of 2200 MHz. The Arc B370 has a base clock of 300 MHz and a boost clock of 2400 MHz, with no game clock listed. Despite the lower base clock, the Arc B370’s boost clock is close to the RX 7700S’s game clock, but the AMD part’s higher shader count and memory bandwidth dominate overall performance.

The process nodes are different: 6 nm for AMD (TSMC foundry) versus 3 nm for Intel (Intel foundry). The Intel part’s smaller process node suggests higher transistor density potential, but its transistor count is unknown, and its measured performance does not reflect any density advantage. Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API compatibility is identical. The RX 7700S has a power draw of 100 W, while the Arc B370 draws 25 W, a fourfold difference that makes the Intel part far more power-efficient in absolute terms.

Head-to-Head Benchmarks

The only direct head-to-head benchmark in the database is 3DMark Steel Nomad DX12. The AMD Radeon RX 7700S scores 2185, while the Intel Arc B370 scores 1184. The AMD GPU wins with a delta of 84.5%. This means the RX 7700S delivers nearly double the performance of the Arc B370 in this DirectX 12 workload. The RX 7700S’s score of 2185 is also consistent with its average benchmark score of 33849 across all recorded tests, while the Arc B370’s average score is just 1184, since it has only one benchmark.

Looking at the RX 7700S’s additional benchmarks, its Geekbench OpenCL score of 62983 is roughly 1.7 times its Geekbench Vulkan score of 36380. This suggests the AMD GPU performs strongly in OpenCL compute workloads, which is relevant for tasks like rendering and machine learning inference. The Vulkan score is also high, indicating solid graphics API performance. The Arc B370 has no such data, so its compute capabilities outside of the single DirectX test remain unmeasured in the database.

The nearest rivals for the RX 7700S further contextualize its performance. Its average score of 33849 is close to the AMD Radeon HD 7950 (average 33951, a 0.3% difference), the AMD Radeon RX 480 (33997, 0.4% difference), the NVIDIA GeForce GTX 1060 5 GB (33694, 0.5% difference in favor of the RX 7700S), and the NVIDIA RTX A5000 (33622, a 0.7% advantage for the RX 7700S). These deltas are tiny, meaning the RX 7700S sits in a performance tier comparable to mid-range desktop GPUs from several generations ago. The Arc B370’s nearest rivals are much older and slower, as noted earlier, which illustrates its low absolute performance.

The delta of 84.5% between the two parts in the head-to-head test is the largest recorded comparison metric. This gap is driven by the RX 7700S’s higher shader count, dedicated memory, and higher bandwidth. The Arc B370’s system-shared memory and lower ROP count (20 versus 64) severely limit its fill rate and memory throughput, which shows up directly in the Steel Nomad DX12 result.

The RX 7700S has a larger transistor count, dedicated memory, and far higher compute rates. The Arc B370 has a smaller process node and much lower power draw, but its performance metrics are drastically lower. The release dates differ by three years, with the AMD part launching in 2023 and the Intel part in 2026. Both use an IGP slot width and have no power connectors, but the RX 7700S uses a PCIe 4.0 x16 bus interface while the Arc B370 uses an integrated-style IGP interface. These specification differences align with the benchmark results, confirming that the RX 7700S is a dedicated mobile graphics solution while the Arc B370 is a low-power integrated-class GPU.
