For context, the RX 7800 XT's individual benchmark scores across the database range from 93 in Passmark DirectX 12 to 54228 in Geekbench Vulkan, while the B370 has no other recorded scores to compare. The absence of additional B370 benchmarks limits the analysis, but the Steel Nomad result alone provides a reliable baseline for the performance hierarchy.

Architecture Differences

The two parts come from fundamentally different design philosophies and market positions. The AMD Radeon RX 7800 XT uses the Navi 32 chip, built on the RDNA 3.0 architecture, with the codename Wheat Nas. It belongs to the Navi III generation, specifically the RX 7000 series, and is fabricated on a 5 nm process at TSMC. The chip contains 28,100 million transistors on a 346 mm² die, yielding a transistor density of 81.2M per mm². This is a large, dedicated discrete GPU designed for desktop graphics workloads.

The Intel Arc B370 uses the Panther Lake chip, built on the Xe3-LPG architecture, and belongs to the Arc Graphics-M generation for Panther Lake. It is fabricated on a 3 nm process at Intel's own foundry. The database lists its transistor count, die size, and transistor density as unknown, which prevents a direct structural comparison. The B370 is an integrated graphics processor, as indicated by its IGP slot width and bus interface, while the RX 7800 XT is a dual-slot discrete card with a PCIe 4.0 x16 interface.

The compute resources differ substantially. The RX 7800 XT has 3840 shading units, 240 texture mapping units, 96 ROPs, and 60 ray tracing cores. The B370 has 1280 shading units, 40 TMUs, 20 ROPs, and 10 ray tracing cores. These numbers translate directly into raw throughput: the RX 7800 XT delivers 37.32 TFLOPS of FP32 performance and the same 37.32 TFLOPS of FP16, reflecting a 1:1 ratio. The B370 delivers 6.144 TFLOPS of FP32 and 12.29 TFLOPS of FP16, a 2:1 ratio that indicates different execution paths for reduced precision workloads.

Clock speeds show a notable inversion. The RX 7800 XT has a base clock of 1295 MHz and a boost clock of 2430 MHz, with a game clock of 2124 MHz. The B370 has a much lower base clock of 300 MHz but a boost clock of 2400 MHz, nearly matching the AMD part's boost. The B370's low base clock suggests aggressive power management, which aligns with its 25 W TDP, while the RX 7800 XT's 263 W TDP supports sustained high-frequency operation.

Memory architecture separates the two completely. The RX 7800 XT uses 16 GB of GDDR6 on a 256-bit bus, providing 624.1 GB/s of bandwidth with a memory clock of 2438 MHz, effective 19.5 Gbps. The B370 uses system shared memory, with the type, bus width, and bandwidth all listed as system dependent. This means the B370 relies on the host system's memory, which introduces latency and bandwidth constraints that a dedicated VRAM pool avoids.

Both parts support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API feature parity exists. The RX 7800 XT outputs via 1x HDMI 2.1a and 3x DisplayPort 2.1, while the B370's display outputs are portable device dependent, reflecting its integrated nature. The RX 7800 XT requires 2x 8-pin power connectors and a 600 W suggested PSU, while the B370 has no power connectors and no suggested PSU, drawing power from the host platform.

Where Each One Wins

The AMD Radeon RX 7800 XT wins in every recorded benchmark category. In the sole head-to-head test, 3DMark Steel Nomad DX12, it outperforms the Intel Arc B370 by 251.1%. The RX 7800 XT also has a broader benchmark footprint, with scores across 10 different tests ranging from Passmark DirectX 12 at 93 to Geekbench Vulkan at 54228. Its average benchmark score of 11627 places it at the 51st percentile, which means it outperforms roughly half of all GPUs in the database.

The RX 7800 XT wins on raw compute throughput. Its FP32 performance of 37.32 TFLOPS is six times higher than the B370's 6.144 TFLOPS. Its texture rate of 583.2 GTexel/s is over six times the B370's 96.00 GTexel/s, and its pixel rate of 233.3 GPixel/s is nearly five times the B370's 48.00 GPixel/s. These ratios indicate a consistent advantage across all shading, texturing, and rasterization workloads.

The RX 7800 XT wins on memory bandwidth. With 624.1 GB/s of dedicated GDDR6 bandwidth, it avoids the system dependent constraints of the B370's shared memory setup. This gives the AMD part a clear advantage in memory-intensive scenarios such as high-resolution textures, large framebuffers, and ray tracing acceleration structures.

The Intel Arc B370 wins on power efficiency in a strict TDP sense. Its 25 W TDP is dramatically lower than the RX 7800 XT's 263 W, meaning the integrated part consumes far less power. The B370 also wins on physical footprint, since it has no separate card dimensions and requires no power connectors, making it suitable for compact portable devices. Its 3 nm process node from Intel represents a more advanced fabrication technology, though the unknown transistor count prevents a density comparison.

The B370 wins on release timing, with a launch date of 2026-01-26, over two years after the RX 7800 XT's 2023-09-05 release. This newer process and architecture generation, Xe3-LPG versus RDNA 3.0, suggests the B370 benefits from more recent design methodologies, even if its absolute performance is far lower.

The Verdict

The data indicates a clear performance hierarchy. The AMD Radeon RX 7800 XT is the superior choice for any workload requiring substantial 3D rendering, compute throughput, or memory bandwidth. Its 251.1% Steel Nomad advantage, combined with its higher shading unit count (3840 versus 1280), higher FP32 throughput (37.32 TFLOPS versus 6.144 TFLOPS), and dedicated 16 GB GDDR6 memory pool, makes it the obvious pick for desktop gaming, content creation, or GPU compute tasks.

The Intel Arc B370 serves a different purpose entirely. Its 25 W TDP, IGP form factor, and lack of discrete memory point to integration in portable or low-power systems where dedicated graphics are not feasible. The B370's 5th percentile ranking and its proximity to legacy parts like the ATI Radeon HD 5770 indicate that its 3D performance is modest, but its 3 nm process and 2026 release date suggest it prioritizes efficiency and platform integration over raw speed.

For users selecting a discrete GPU for a desktop build, the RX 7800 XT is the only viable option between these two, given its active production status, PCIe 4.0 x16 interface, and physical card design. For users in the market for an integrated graphics solution, the B370 offers a modern architecture with a very low power envelope, but its benchmark results show it cannot compete with the RX 7800 XT in any recorded performance metric. The choice comes down to form factor and power constraints versus absolute performance, and the database shows no scenario where the B370 outperforms the RX 7800 XT in actual benchmarks.
