AMD Radeon 780M vs AMD Radeon Pro 5700 XT Comparison

The AMD Radeon Pro 5700 XT and AMD Radeon 780M occupy opposite ends of the graphics spectrum, yet both carry the Radeon name. The Pro 5700 XT is a dedicated, end-of-life workstation part built on RDNA 1.0, while the 780M is an active integrated graphics processor (IGP) from the RDNA 3.0 generation. Benchmark data shows a clear performance hierarchy, but the 780M’s existence in a low-power IGP package makes it a compelling option for specific use cases where the Pro 5700 XT simply cannot operate.

Where Each One Wins

The data splits cleanly by workload and physical constraints. The AMD Radeon Pro 5700 XT wins every head-to-head benchmark recorded in the data, taking both available tests with decisive margins. Its average benchmark score of 18685 places it at the 63rd percentile of all GPUs, while the 780M’s average of 17588 sits at the 61st percentile. The Pro 5700 XT’s nearest rival is the NVIDIA GeForce RTX 2070, which it trails by 0.6%, and it leads the AMD Radeon RX 560X by just 0.3%. The 780M, meanwhile, is essentially tied with the NVIDIA GeForce RTX 4060, scoring 0.3% lower, and edges out the AMD Radeon Pro 560 by 0.2%.

The 780M wins in a category no benchmark can measure: power envelope. With a 15 W TDP and no power connectors, it is designed for systems where a dedicated card with a 130 W TDP and a 300 W suggested PSU would be impossible. The Pro 5700 XT requires a PCIe 4.0 x16 slot and external power, whereas the 780M uses a PCIe 4.0 x8 interface and draws everything from the motherboard. For a compact or portable build, the 780M is the only viable option between the two.

Architecture Differences

The architectural gap is vast. The Pro 5700 XT uses the Navi 10 chip on a 7 nm TSMC process, packing 10,300 million transistors into a 251 mm² die for a density of 41.0 million transistors per mm². The 780M uses the Phoenix chip on a 4 nm TSMC process, fitting 25,390 million transistors into a smaller 178 mm² die, achieving a density of 142.6 million transistors per mm² — over three times denser. This explains how the 780M delivers competitive compute performance at a fraction of the power.

Core counts differ substantially. The Pro 5700 XT has 2560 shading units, 160 texture mapping units (TMUs), and 64 raster operation pipelines (ROPs). The 780M has 768 shading units, 48 TMUs, and 32 ROPs. Despite having fewer than a third of the shading units, the 780M achieves higher peak FP32 throughput: 8.909 TFLOPS versus 7.675 TFLOPS. The 780M also runs at a much higher boost clock of 2900 MHz compared to 1499 MHz on the Pro 5700 XT. The 780M includes 12 ray tracing cores, a feature entirely absent from the Pro 5700 XT, and supports DirectX 12 Ultimate (12_2) versus the older DirectX 12 (12_1). Memory architecture is another clear split: the Pro 5700 XT has 16 GB of dedicated GDDR6 on a 256-bit bus with 384.0 GB/s bandwidth, while the 780M uses system shared memory with bandwidth described as system dependent.

Head-to-Head Benchmarks

In Geekbench OpenCL, the Pro 5700 XT scores 59467 against the 780M’s 18602, a delta of 219.7% in favor of the dedicated card. That is a massive margin — more than three times the raw compute score. The result aligns with the Pro 5700 XT’s dedicated memory bandwidth of 384.0 GB/s and its larger shading unit count. The 780M’s lower FP16 throughput (8.909 TFLOPS at 1:1 ratio) versus the Pro 5700 XT’s 15.35 TFLOPS (2:1 ratio) also contributes to the gap in compute-heavy OpenCL workloads.

In Geekbench Vulkan, the margin narrows considerably. The Pro 5700 XT scores 56593, while the 780M reaches 33683, a 68% advantage for the Pro 5700 XT. The 780M’s modern RDNA 3.0 architecture with ray tracing cores and higher boost clock helps it close the gap relative to OpenCL, but the raw throughput difference remains decisive. The Pro 5700 XT’s pixel rate of 95.94 GPixel/s edges out the 780M’s 92.80 GPixel/s, while its texture rate of 239.8 GTexel/s far exceeds the 780M’s 139.2 GTexel/s.

Beyond the direct comparison, the Pro 5700 XT shows strength in legacy DirectX benchmarks: it scores 153 in Passmark DirectX 9 and 85 in DirectX 11, versus its own 76 in DirectX 10 and 59 in DirectX 12. The 780M has no comparable legacy scores in the data, but its 3DMark Steel Nomad DX12 score of 480 gives a modern gaming reference point. The Pro 5700 XT’s Passmark G3D score of 12547 and GPU compute score of 5787 further illustrate its compute-oriented design, while the 780M’s Geekbench OpenCL score of 18602 and Vulkan score of 33683 show a more balanced profile for its class.

The Verdict

Choose the AMD Radeon Pro 5700 XT if you need uncompromising compute performance and have the physical space and power budget for a dedicated card. Its 219.7% OpenCL lead and 68% Vulkan lead over the 780M are not incremental — they are generational. The 16 GB of dedicated GDDR6 memory on a 256-bit bus eliminates any dependency on system RAM, making it suitable for large datasets or multi-tasking with memory-heavy applications. The data shows it performs on par with the NVIDIA GeForce RTX 2070, trailing by only 0.6%, and slightly ahead of the AMD Radeon RX 560X. Its 63rd percentile ranking across all GPUs reflects a solid mid-to-upper tier position.

Choose the AMD Radeon 780M if power efficiency and integration are non-negotiable. At 15 W TDP with no external power connectors, it operates where a 130 W card cannot. Its 61st percentile ranking is remarkably close to the Pro 5700 XT’s 63rd, especially considering the 780M achieves this with system shared memory and a PCIe 4.0 x8 interface. The 780M’s 8.909 TFLOPS FP32 output actually exceeds the Pro 5700 XT’s 7.675 TFLOPS, and its modern RDNA 3.0 architecture brings ray tracing and DirectX 12 Ultimate support that the older card lacks entirely. For an ultra-portable laptop or a small form factor build where every watt counts, the 780M delivers a surprising amount of performance.
