AMD Radeon 780M vs Intel Arc B570 Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive performance gap between the Intel Arc B570 and the AMD Radeon 780M across every shared test. The Intel Arc B570 wins all three head-to-head comparisons, with margins that range from substantial to overwhelming. The most lopsided result comes from the 3DMark Steel Nomad DX12 test, where the Arc B570 scores 2649 against the Radeon 780M's 480. That is a 451.9% advantage, meaning the Intel part delivers more than five times the frame throughput in this modern DirectX 12 workload. This is not a near-miss scenario; it is a category difference.

In Geekbench OpenCL, the Arc B570 posts 83514 points versus 18602 for the Radeon 780M, a 349% delta. This test stresses raw compute throughput, and the Intel card's dedicated GDDR6 memory and higher shading unit count allow it to run away from the integrated AMD solution. The gap narrows somewhat in Geekbench Vulkan, but only relatively: the Arc B570 scores 96844 against 33683, a 187.5% lead. Vulkan tends to scale well on AMD architectures, yet even here the Radeon 780M cannot close the distance. The data indicates that the Intel Arc B570 is the faster GPU in every measured scenario, with no test where the AMD part takes the lead.

Looking at the broader database averages, the Arc B570 sits at an average benchmark score of 20556, placing it in the 65th percentile of all GPUs. Its nearest rivals include the NVIDIA GeForce RTX 3070 Mobile at 20534 (0.1% behind), the Intel Arc A750 at 20582 (0.1% ahead), the NVIDIA Quadro M4000M at 20480 (0.4% behind), and the AMD Radeon R9 M390X at 20662 (0.5% ahead). The Arc B570 is effectively trading blows with these cards, which all fall within a 0.5% band of each other. This tells you the B570 is not an outlier; it is a solid mid-range discrete GPU that slots between mobile RTX 3070 performance and last-gen desktop cards like the Arc A750.

The Radeon 780M, by contrast, averages 17588 points, placing it in the 61st percentile. Its nearest rivals are the AMD Radeon Pro 560 at 17551 (0.2% behind), the NVIDIA GeForce RTX 4060 at 17639 (0.3% ahead), the AMD Radeon HD 7790 at 17666 (0.4% ahead), and the AMD Radeon Pro 460 at 17509 (0.5% behind). So the 780M is competitive with older desktop cards like the HD 7790 and entry-level pro GPUs, but it is nowhere near the performance class of the Arc B570. The average score difference of 2968 points (20556 vs 17588) represents a 16.9% gap at the aggregate level, though the head-to-head deltas are far larger because those tests favor the discrete card's dedicated memory bandwidth.

The Verdict

From the data alone, the choice is unambiguous for anyone who needs raw graphics performance: the Intel Arc B570 is the winner in every recorded benchmark, with margins of 187.5% to 451.9%. If you are building a system where frame rates and compute throughput matter, the B570 is the only rational pick between these two. The Radeon 780M does not win a single test in the head-to-head comparison, and its average score is roughly 14.5% lower than the B570's.

However, the verdict is not purely about speed. The Radeon 780M is an integrated GPU (IGP) with a 15 W TDP, no power connectors, and system-shared memory. That makes it the only choice for thin-and-light laptops or mini PCs where a discrete card physically cannot fit. The Arc B570, in contrast, is a dual-slot, 150 W board requiring a 1x 8-pin power connector and a 450 W power supply. You cannot drop a B570 into a machine designed for a 780M. So the verdict splits along form factor lines: if you have the slot and power budget, the B570 destroys the 780M; if you are constrained to an IGP, the 780M is what you get, and the comparison becomes moot.

The percentile data reinforces this. The B570 sits at the 65th percentile of all GPUs, meaning it outranks most discrete cards in the database. The 780M sits at the 61st percentile, which is remarkably high for an integrated solution but still below the B570. The fact that the 780M is only 4 percentile points behind despite being an IGP confirms its efficiency, but it does not change the performance hierarchy. For a desktop builder with a dedicated GPU slot, the B570 is the clear winner. For an ultraportable or embedded system, the 780M is the only viable option, and it performs admirably for its class.

Where Each One Wins

The Intel Arc B570 wins in every measurable compute and graphics scenario from the recorded benchmarks. Its 3DMark Steel Nomad score of 2649 demonstrates strong DirectX 12 gaming performance, and its Geekbench OpenCL score of 83514 shows heavy compute throughput for tasks like rendering or physics simulation. The Vulkan score of 96844 further cements its position as a versatile performer across modern graphics APIs. If your workload is gaming, 3D rendering, or GPU-accelerated compute, the B570 is the part to choose.

The AMD Radeon 780M wins in power efficiency and system integration, though these wins are not captured in the head-to-head numbers. Its 15 W TDP versus the B570's 150 W means it draws an order of magnitude less power. It requires no external power connectors, no dedicated cooling solution beyond what the CPU gets, and no additional board space. It also has a higher boost clock of 2900 MHz versus the B570's 2500 MHz, but that does not translate into performance wins because the 780M has far fewer shading units and relies on shared system memory. The 780M is the right choice for passive or low-power designs, but it does not win any performance benchmark.

Architecture Differences

The two GPUs come from fundamentally different design philosophies. The Intel Arc B570 uses the BMG-G21 chip built on TSMC's 5 nm process, with 19,600 million transistors packed into a 272 mm² die. This yields a transistor density of 72.1 million per square millimeter. The architecture is Xe2-HPG, part of the Battlemage generation (Arc 5). It is a discrete graphics card with dedicated GDDR6 memory, 10 GB at a 160-bit bus width, delivering 380.0 GB/s of bandwidth. The memory clock is 2375 MHz with 19 Gbps effective speed.

The AMD Radeon 780M uses the Phoenix chip on TSMC's 4 nm process, with 25,390 million transistors on a smaller 178 mm² die. That gives it a much higher transistor density of 142.6 million per square millimeter. The architecture is RDNA 3.0, from the Navi III IGP generation. It is an integrated GPU with no dedicated memory; it uses System Shared memory with bandwidth that is System Dependent. The base clock is 800 MHz with a boost of 2900 MHz, which is higher than the B570's flat 2500 MHz boost, but the 780M has only 768 shading units versus the B570's 2304.

The Intel card has 144 texture mapping units and 80 ROPs, compared to 48 TMUs and 32 ROPs on the AMD part. Ray tracing cores also differ: 18 on the B570 versus 12 on the 780M. The pixel rate is 200.0 GPixel/s for Intel versus 92.8 GPixel/s for AMD, and the texture rate is 360.0 GTexel/s versus 139.2 GTexel/s. FP32 compute is 11.52 TFLOPS for the B570 versus 8.909 TFLOPS for the 780M. Notably, the B570 has a 2:1 FP16 ratio (23.04 TFLOPS), while the 780M runs FP16 at 1:1 (8.909 TFLOPS), meaning Intel has a much larger half-precision advantage.

Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API support is identical. The B570 uses PCIe 4.0 x8, and the 780M also uses PCIe 4.0 x8. Display outputs differ: the B570 has 1x HDMI 2.1a and 3x DisplayPort 2.1, while the 780M's outputs are motherboard dependent. The B570 is a dual-slot card measuring 272 mm in length and 115 mm in height, while the 780M is an IGP with no physical dimensions or slot width.
