AMD Radeon 780M vs Intel Arc B370 Comparison

Head-to-Head Benchmarks

The only direct comparison available in the database is the 3DMark Steel Nomad DX12 test, and the result is decisive in favor of the Intel Arc B370. The Intel part scores 1184 points, while the AMD Radeon 780M manages 480 points. That is a delta of 59.5 percent, meaning the Intel Arc B370 delivers more than double the frame rate in this particular workload. This is not a marginal victory; it is a complete inversion of what the average benchmark scores might suggest, and it indicates that the Intel architecture is far better suited to modern DirectX 12 rendering tasks.

Looking at the broader benchmark picture, the AMD Radeon 780M has an average benchmark score of 17588 across three tests: 3DMark Steel Nomad DX12 at 480, Geekbench OpenCL at 18602, and Geekbench Vulkan at 33683. The Intel Arc B370, by contrast, has only a single recorded benchmark, the same 3DMark Steel Nomad DX12 run at 1184, giving it an average score of 1184. The discrepancy between the average scores is enormous, but that is largely a function of the test suites available. The AMD part has two additional OpenCL and Vulkan results that pull its average upward, while the Intel part has no such entries in the database. When comparing only the shared test, the Intel Arc B370 is clearly ahead.

The percentile ranking tells a different story. The AMD Radeon 780M sits at the 61st percentile of all GPUs, while the Intel Arc B370 sits at the 5th percentile. This is a striking contrast. The AMD part, despite losing the head-to-head 3DMark test, ranks far higher globally because its OpenCL and Vulkan scores are strong enough to place it above most discrete and integrated graphics solutions. The Intel part, with only one benchmark, ranks near the bottom, though this may reflect a sparse data set rather than true performance. The nearest rivals for the Intel Arc B370, such as the ATI Mobility Radeon HD 5570 with an average score of 1186 and delta of 0.2 percent, the ATI Radeon HD 5770 at 1190 with a delta of 0.5 percent, and the AMD Radeon HD 7650M at 1192 with a delta of 0.7 percent, all sit within a hair of its average. The AMD FirePro M2000 trails slightly at 1168 with a delta of 1.4 percent. The Intel part is essentially tied with these older discrete GPUs in the one test measured.

For the AMD Radeon 780M, the nearest rivals are much stronger overall. The AMD Radeon Pro 560 averages 17551, a delta of 0.2 percent ahead of the 780M. The NVIDIA GeForce RTX 4060 averages 17639, a delta of 0.3 percent behind the 780M. The AMD Radeon HD 7790 averages 17666, a delta of 0.4 percent behind. The AMD Radeon Pro 460 averages 17509, a delta of 0.5 percent ahead. These rivals bracket the 780M closely, indicating that its average score of 17588 places it squarely in the company of mid-range discrete GPUs from several generations, despite being an integrated solution.

Architecture Differences

The AMD Radeon 780M is built on the Phoenix chip using RDNA 3.0 architecture, manufactured on a 4 nanometer process at TSMC. The transistor count is 25,390 million, and the die size is 178 square millimeters, yielding a transistor density of 142.6 million transistors per square millimeter. The Intel Arc B370 uses the Panther Lake chip with Xe3-LPG architecture, manufactured on a 3 nanometer process at Intel. The transistor count and die size are recorded as unknown, so no direct density comparison is possible.

The AMD part has 768 shading units, 48 texture mapping units, and 32 render output units. It also includes 12 ray tracing cores. The Intel part has 1280 shading units, 40 texture mapping units, and 20 render output units, with 10 ray tracing cores. The raw shader count favors Intel by a wide margin, but the texture and pixel throughput tell a more nuanced story. The AMD Radeon 780M achieves a pixel rate of 92.80 gigapixels per second and a texture rate of 139.2 gigatexels per second. The Intel Arc B370 achieves 48.00 gigapixels per second and 96.00 gigatexels per second. Despite having fewer TMUs and ROPs, the AMD part processes textures and pixels faster, likely due to its higher clock speed.

Clock speeds differ substantially. The AMD Radeon 780M has a base clock of 800 MHz and a boost clock of 2900 MHz. The Intel Arc B370 has a base clock of 300 MHz and a boost clock of 2400 MHz. The AMD part boosts 500 MHz higher, which explains its superior fill rates. Floating point performance also diverges. The AMD Radeon 780M delivers 8.909 TFLOPS of FP32 performance and the same 8.909 TFLOPS for FP16 at a 1:1 ratio. The Intel Arc B370 delivers 6.144 TFLOPS of FP32 and 12.29 TFLOPS of FP16 at a 2:1 ratio. The AMD part is faster for single-precision work, while the Intel part has a clear advantage for half-precision workloads, which can matter in certain compute and AI applications.

Both parts use system shared memory, with no dedicated VRAM, and both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The power draw is recorded at 15 watts for the AMD part and 25 watts for the Intel part, a notable difference for integrated graphics. Both are IGP slot width with no power connectors. The bus interface is PCIe 4.0 x8 for the AMD part, while the Intel part is listed simply as IGP. Display outputs are motherboard dependent for AMD and portable device dependent for Intel.

The AMD Radeon 780M was released on January 30, 2024, while the Intel Arc B370 has a release date of January 26, 2026. The AMD part has a predecessor, Navi II IGP, and a successor, Navi III IGP. The Intel part has no predecessor or successor listed.

Where Each One Wins

The Intel Arc B370 wins the only direct head-to-head benchmark, the 3DMark Steel Nomad DX12 test, by a large margin. This suggests that for modern DirectX 12 gaming workloads, the Intel part is substantially stronger. The higher shading unit count and the 2:1 FP16 ratio also give it an edge in compute tasks that leverage half-precision arithmetic. The Intel part is also built on a newer 3 nanometer process, which may offer efficiency benefits despite the higher 25 watt TDP.

The AMD Radeon 780M wins in several other respects. It has higher clock speeds, with a boost of 2900 MHz versus 2400 MHz, and it delivers superior pixel and texture fill rates. Its FP32 performance is higher, making it better suited for single-precision compute. The AMD part also has a much higher percentile ranking, at 61 compared to 5, and a far higher average benchmark score, 17588 versus 1184, though this is influenced by the additional OpenCL and Vulkan tests in its data set. The AMD part is also older, with a 2024 release date, and has a lower TDP at 15 watts.

For gaming with ray tracing, both parts have dedicated ray tracing cores, but the AMD part has 12 versus 10 for Intel. The AMD part also has more TMUs and ROPs, which helps with traditional rasterization throughput. The Intel part has more shading units, which can help in shader-heavy workloads.

The Verdict

The recorded data paints a split picture. In the only shared benchmark, the Intel Arc B370 is clearly superior, delivering 1184 points versus 480 for the AMD Radeon 780M, a 59.5 percent advantage. This makes the Intel part the better choice for anyone prioritizing DirectX 12 gaming performance in a modern integrated GPU. The fact that its nearest rivals are older discrete cards like the ATI Radeon HD 5770 and AMD Radeon HD 7650M, all within a fraction of a percent, suggests it performs like a modest discrete GPU from a past generation, which is respectable for an IGP.

The AMD Radeon 780M, however, has a much stronger overall profile. Its average benchmark score of 17588 places it alongside the NVIDIA GeForce RTX 4060, a modern discrete GPU, and its 61st percentile ranking shows it outperforms the majority of all GPUs in the database. The Geekbench Vulkan score of 33683 is particularly strong. For users who run a mix of OpenCL and Vulkan workloads, or who need higher FP32 throughput and faster pixel and texture fill rates, the AMD part is the more versatile option. Its lower 15 watt TDP also makes it better suited for power-constrained portable devices.

The choice depends on the workload. If the priority is a single modern DirectX 12 benchmark, the Intel Arc B370 wins outright. If the priority is overall compute versatility, global ranking, and lower power draw, the AMD Radeon 780M is the stronger candidate. The data does not support a universal winner; it supports two different profiles for two different use cases.
