AMD Radeon RX 6450M vs Intel Arc B370 Comparison

AMD Radeon RX 6450M and Intel Arc B370 are both mobile integrated or low-profile graphics solutions, but they occupy very different positions in the performance spectrum according to the recorded database metrics. The RX 6450M is part of the Radeon RX 6000 series, built on the Navi 24 chip with RDNA 2.0 architecture, while the Arc B370 uses the Panther Lake chip with Xe3-LPG architecture from Intel. Neither product carries a launch MSRP in the database, so no pricing information is available for this comparison.

Head-to-Head Benchmarks

The database contains a single recorded benchmark result for the Intel Arc B370, and no benchmark entries for the AMD Radeon RX 6450M. The Arc B370 achieved a score of 1184 in the 3DMark Steel Nomad DX12 test. This places the Arc B370 at the 5th percentile among all GPUs in the database, indicating that it sits near the lower end of the performance distribution. The RX 6450M, by contrast, holds a 50th percentile ranking across all GPUs, which places it squarely in the middle of the overall performance range. With an average benchmark score of zero recorded for the RX 6450M, there is no direct head-to-head score from the same test to compare against the Arc B370’s 1184 points.

The nearest rivals for the Arc B370 provide context for its score. The ATI Mobility Radeon HD 5570 averages 1186 points, which is 0.2% higher than the Arc B370’s result. The ATI Radeon HD 5770 averages 1190 points, a 0.5% advantage. The AMD Radeon HD 7650M averages 1192 points, sitting 0.7% above the Arc B370. The AMD FirePro M2000 averages 1168 points, which is 1.4% lower than the Arc B370. These deltas are small, all within a range of roughly 2 percentage points, meaning the Arc B370 performs nearly identically to these older discrete mobile parts in the Steel Nomad workload. The RX 6450M has no nearest rivals listed in the database, so no similar comparison is possible for it.

Because the RX 6450M lacks any recorded benchmark scores, the data cannot support a direct numerical comparison between the two products. The percentile fields are the only quantitative bridge between them. The RX 6450M’s 50th percentile versus the Arc B370’s 5th percentile suggests a substantial gap in overall capability, but this inference comes from aggregate database rankings rather than a shared test result. The Arc B370’s single score of 1184 is the only concrete benchmark datum available, and it anchors that GPU near the bottom of the distribution.

Where Each One Wins

The RX 6450M wins on raw compute throughput based on the recorded specifications. It delivers 3.779 TFLOPS of FP32 performance, while the Arc B370 delivers 6.144 TFLOPS. This means the Arc B370 is approximately 62.6% ahead of the RX 6450M in FP32 throughput, a clear mathematical advantage derived from the listed figures. In FP16, the Arc B370 produces 12.29 TFLOPS compared to the RX 6450M’s 7.557 TFLOPS, again showing the Intel part ahead by a wide margin. Texture rate follows the same pattern: the RX 6450M reaches 118.1 GTexel/s, while the Arc B370 reaches 96.00 GTexel/s, so the AMD part wins here by about 23%. Pixel rate also favors the RX 6450M, which achieves 78.72 GPixel/s versus the Arc B370’s 48.00 GPixel/s, a lead of roughly 64%.

Memory configuration gives the RX 6450M a dedicated advantage. It has 4 GB of GDDR6 memory on a 64-bit bus, providing 128.0 GB/s of bandwidth. The Arc B370 uses system shared memory with system dependent bandwidth, so it cannot match a fixed dedicated memory pool. For workloads that rely on consistent local memory access, the RX 6450M’s dedicated GDDR6 is a structural win. The Arc B370’s shared memory approach depends entirely on the host system’s memory subsystem, which the database lists as system dependent.

Clock speeds also differentiate the two. The RX 6450M has a base clock of 2000 MHz, a boost clock of 2460 MHz, and a game clock of 2220 MHz. The Arc B370 has a base clock of 300 MHz and a boost clock of 2400 MHz. The RX 6450M sustains a much higher base frequency, which can benefit steady-state workloads, while the Arc B370’s very low base clock suggests it relies on boost behavior for most of its performance. The RX 6450M’s memory clock is listed as 2000 MHz with 16 Gbps effective, while the Arc B370’s memory clock is system shared.

Architecture Differences

The two GPUs come from different manufacturers and architectures. AMD’s RX 6450M uses the Navi 24 chip built on RDNA 2.0, fabricated on a 6 nm process at TSMC. It contains 5,400 million transistors on a 107 mm² die, yielding a transistor density of 50.5 million per square millimeter. Intel’s Arc B370 uses the Panther Lake chip with Xe3-LPG architecture, fabricated on a 3 nm process at Intel. The database lists its transistor count and die size as unknown, so no density figure exists for comparison.

The RX 6450M has 768 shading units, 48 texture mapping units, and 32 render output units. The Arc B370 has 1280 shading units, 40 TMUs, and 20 ROPs. The Arc B370 has more shaders but fewer texture units and ROPs, which explains why its FP32 throughput is higher while its texture and pixel rates are lower. Ray tracing cores differ as well: the RX 6450M has 12 RT cores, while the Arc B370 has 10 RT cores. Neither product lists tensor cores, so AI acceleration hardware is not specified for either.

The process node difference is significant. The Intel part uses a 3 nm process, which is denser than AMD’s 6 nm process, but the database does not provide Intel’s actual transistor count or die size, so the practical density advantage cannot be quantified. The RX 6450M’s 6 nm process is older but still active in production. Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so their API feature sets match. The RX 6450M uses a PCIe 4.0 x4 bus interface, while the Arc B370 is listed as IGP, meaning it is integrated into the host processor and does not use a discrete PCIe connection. Both are IGP in slot width, which means they occupy no expansion slot. Neither uses external power connectors.

The RX 6450M has a TDP of 50 W, while the Arc B370 has a TDP of 25 W. This makes the Intel part half the power draw of the AMD part. The RX 6450M was released on January 3, 2023, while the Arc B370 was released on January 26, 2026, so the Intel product is newer by roughly three years. The RX 6450M lists Polaris Mobile as its predecessor, while the Arc B370 has no predecessor listed.

The Verdict

The recorded data points to a split decision based on workload characteristics. The Intel Arc B370 holds the compute advantage in FP32 and FP16 throughput, with 6.144 TFLOPS and 12.29 TFLOPS respectively, against the RX 6450M’s 3.779 TFLOPS and 7.557 TFLOPS. This gives the Arc B370 a clear lead in shader-heavy tasks that scale with raw floating-point throughput. Its 1280 shading units provide a wider parallel execution width, and its newer 3 nm process suggests a more advanced manufacturing approach, though the database lacks transistor and die size figures to confirm density benefits.

The AMD Radeon RX 6450M counters with wins in texture rate, pixel rate, and dedicated memory. Its 118.1 GTexel/s texture fill and 78.72 GPixel/s pixel fill exceed the Arc B370’s 96.00 GTexel/s and 48.00 GPixel/s. The RX 6450M also has 48 TMUs versus 40, and 32 ROPs versus 20, which explains its higher fill rates. Its 4 GB of GDDR6 with 128.0 GB/s bandwidth provides a fixed memory pool, unlike the Arc B370’s system shared memory, which varies with the host platform.

The percentile rankings reinforce the separation. The RX 6450M sits at the 50th percentile among all GPUs, while the Arc B370 sits at the 5th percentile. The Arc B370’s only benchmark score of 1184 places it near the ATI Mobility Radeon HD 5570, ATI Radeon HD 5770, and AMD Radeon HD 7650M, all within about one point of its result. That cluster of scores suggests the Arc B370 performs in a legacy tier, despite its 2026 release date. The RX 6450M’s middle-of-the-pack percentile, combined with its higher fill rates and dedicated memory, points to a more capable overall part for rasterization-oriented tasks.

Power draw favors the Arc B370 at 25 W, exactly half the RX 6450M’s 50 W. For systems where energy efficiency is the priority, the Intel part uses less power while delivering higher FP32 throughput, but it loses on memory bandwidth and fill rates. The RX 6450M’s PCIe 4.0 x4 interface gives it a discrete bus connection, while the Arc B370 is IGP, meaning it shares the host processor’s memory path.

The verdict from the data is that the RX 6450M is the stronger choice for scenarios involving texture-heavy rendering, high pixel output, or consistent local memory access, given its dedicated GDDR6 and higher pixel/texture rates. The Arc B370 is the better fit for compute-bound workloads that leverage FP32 or FP16 throughput, and for low-power designs where 25 W is a hard limit. The absence of any direct benchmark score for the RX 6450M limits precision, but the specification differences and percentile fields provide enough signal to separate them. Users seeking maximum shader throughput and minimal power draw should look at the Arc B370. Users needing dedicated memory bandwidth and higher fill rates should look at the RX 6450M.
