AMD Radeon RX 9050 vs Intel Arc B370 Comparison

Where Each One Wins

The recorded data splits these two graphics solutions into completely different performance tiers. The AMD Radeon RX 9050 holds a decisive advantage in raw compute and rasterization throughput, while the Intel Arc B370 occupies a position far lower in the overall GPU hierarchy. The database places the RX 9050 at the 50th percentile among all GPUs, meaning it sits exactly at the midpoint of the entire recorded range. The Arc B370, by contrast, sits at the 5th percentile, indicating that nearly all other recorded GPUs outperform it. This is not a close contest by any metric.

Where the RX 9050 wins is in every category that requires sustained pixel output, texture work, and floating-point computation. Its pixel rate of 166.4 GPixel/s versus 48.00 GPixel/s for the Arc B370 represents a 3.47x advantage in fill-rate-limited scenes. Its texture rate of 166.4 GTexel/s versus 96.00 GTexel/s gives it a 1.73x lead in texture-bound workloads. In FP32 compute, the RX 9050 delivers 10.65 TFLOPS, which is 73% higher than the Arc B370's 6.144 TFLOPS. These are the numbers that determine real-world gaming and rendering performance, and they all point the same direction.

The Arc B370 wins only in scenarios where its integrated nature and extremely low power draw are the deciding factors. Its 25 W TDP versus the RX 9050's 92 W TDP means it can operate in systems with no dedicated power connectors, using the IGP bus interface and system-shared memory. The RX 9050 requires a PCIe 5.0 x16 slot and a single 8-pin power connector with a 250 W suggested power supply. For portable devices or low-power embedded systems, the Arc B370's existence is a win, but that is not a performance win. In every benchmark category recorded, the RX 9050 is the superior part.

Architecture Differences

The two chips come from fundamentally different design philosophies. The RX 9050 uses the Navi 44 chip built on RDNA 4.0 architecture, manufactured on a 4 nm process at TSMC. It packs 29,700 million transistors into a 199 mm² die, yielding a transistor density of 149.2 million per square millimeter. The Arc B370 uses the Panther Lake chip with Xe3-LPG architecture, built on Intel's 3 nm process. Its transistor count and die size are listed as unknown, so no density comparison is possible from the recorded data.

The memory subsystems diverge completely. The RX 9050 has dedicated 8 GB of GDDR6 memory on a 128-bit bus, delivering 288.0 GB/s of bandwidth. The Arc B370 uses system-shared memory, meaning its capacity, bus width, and bandwidth are all system dependent. This is the single most important architectural difference for gaming. A dedicated memory pool with fixed bandwidth allows the RX 9050 to deliver consistent performance regardless of what else the system is doing. The Arc B370 must share memory bandwidth with the CPU and other system components, which introduces unpredictable performance swings.

The compute resources also differ in structure. The RX 9050 has 1024 shading units, 64 TMUs, 64 ROPs, and 16 ray tracing cores. The Arc B370 has 1280 shading units, 40 TMUs, 20 ROPs, and 10 ray tracing cores. The higher shading unit count on the Intel part does not translate into higher performance because its clock speeds are far lower and its FP32 rate is capped by other limits. The RX 9050's base clock of 1330 MHz and boost clock of 2600 MHz dwarf the Arc B370's 300 MHz base and 2400 MHz boost. The Intel part's very low base clock suggests it is designed for burst workloads rather than sustained heavy rendering.

The RX 9050 supports FP16 at a 1:1 ratio with FP32, both at 10.65 TFLOPS. The Arc B370 supports FP16 at a 2:1 ratio, delivering 12.29 TFLOPS. This means the Intel part actually has higher FP16 throughput, but this advantage is unlikely to matter in consumer workloads, which are dominated by FP32. Both chips support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RX 9050 is a dual-slot discrete card with HDMI 2.1b and DisplayPort 2.1a outputs, while the Arc B370 is an integrated graphics processor with portable device dependent display outputs.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between these two GPUs. The winsA and winsB counters are both zero, and the headToHeadBenchmarks array is empty. This means the comparison must be built from the individual recorded benchmarks and architectural specifications.

The only benchmark score recorded for either part belongs to the Arc B370. It scored 1184 in the 3DMark Steel Nomad DX12 test. The RX 9050 has no recorded benchmark scores in the database, which limits direct numerical comparison. However, the percentile data provides context. The Arc B370's score places it at the 5th percentile of all GPUs, with an average benchmark score of 1184. The RX 9050 sits at the 50th percentile, suggesting its average benchmark score would be substantially higher, though that exact number is not recorded.

The Arc B370's nearest rivals in the database are all legacy parts with scores very close to its own. The ATI Mobility Radeon HD 5570 scored 1186, just 0.2% higher. The ATI Radeon HD 5770 scored 1190, 0.5% higher. The AMD Radeon HD 7650M scored 1192, 0.7% higher. The AMD FirePro M2000 scored 1168, which is 1.4% lower. This clustering around the 1184 score confirms that the Arc B370 performs at the level of GPUs from roughly a decade earlier. Its 5th percentile ranking means it outperforms only a small fraction of the recorded GPU population.

The RX 9050 has no nearest rivals listed in the database. This is consistent with its position at the exact median of all GPUs, where no single closest competitor stands out. Its architectural specifications point to performance that is roughly two orders of magnitude above the Arc B370 in fill rate and more than 70% above in FP32 compute. The pixel rate difference alone, 166.4 GPixel/s versus 48.00 GPixel/s, would manifest as a massive frame rate gap in any resolution-limited scenario.

Specification Differences

The two parts differ in nearly every specification field recorded in the database. The process nodes are different: 4 nm at TSMC for the RX 9050 versus 3 nm at Intel for the Arc B370. The RX 9050 has a known transistor count of 29,700 million and a die size of 199 mm². The Arc B370 has unknown transistor count and die size.

Clock speeds show the RX 9050 running at 1330 MHz base and 2600 MHz boost, with a game clock of 1920 MHz. The Arc B370 runs at 300 MHz base and 2400 MHz boost, with no game clock recorded. Memory clock for the RX 9050 is 2250 MHz, delivering 18 Gbps effective. The Arc B370's memory clock is system shared.

Memory configuration is the largest divergence. The RX 9050 has 8 GB of GDDR6 on a 128-bit bus with 288.0 GB/s bandwidth. The Arc B370 has system-shared memory with system-dependent bandwidth. The RX 9050 has 1024 shading units, 64 TMUs, 64 ROPs, and 16 RT cores. The Arc B370 has 1280 shading units, 40 TMUs, 20 ROPs, and 10 RT cores.

Slot width differs: dual-slot for the RX 9050, IGP for the Arc B370. Power connectors are 1x 8-pin for the RX 9050, none for the Arc B370. The RX 9050 has a suggested PSU of 250 W; the Arc B370 has none recorded. Bus interface is PCIe 5.0 x16 for the RX 9050, IGP for the Arc B370.
