AMD Radeon 780M vs AMD Radeon RX 7600 Comparison

Where Each One Wins

The recorded benchmark data splits cleanly between these two AMD Radeon parts. The AMD Radeon RX 7600 wins all three head-to-head tests outright, with the widest margins appearing in compute-oriented and DirectX 12 workloads. The AMD Radeon 780M does not take a single victory in the shared test set, but its strengths emerge in a different context: its Geekbench Vulkan score sits remarkably close to the discrete card, trailing by only 2.1%. That narrow gap in Vulkan suggests the integrated part can handle API-level workloads with surprising competence, even if its raw throughput is far lower.

For use-case splits, the RX 7600 is the clear choice for any application that leans on OpenCL compute, as its Geekbench OpenCL score of 88,051 dwarfs the 780M's 18,602, a difference of 78.9%. DirectX 12 gaming via the 3DMark Steel Nomad test also heavily favors the RX 7600, which scores 2,310 against 480, a 79.2% advantage. The 780M, by contrast, shows its best relative performance in Vulkan, where it reaches 33,683 versus 34,401. This makes the integrated GPU a viable option for Vulkan-based titles or workloads at modest settings, while the discrete card remains the pick for compute-heavy tasks and higher-end DirectX 12 gaming.

Head-to-Head Benchmarks

The 3DMark Steel Nomad DX12 test delivers the clearest separation. The RX 7600 posts 2,310 points, while the 780M manages only 480. That is a 79.2% deficit for the integrated chip, and the margin reflects the vast difference in shading units, texture units, and memory bandwidth. The RX 7600's 2048 shading units and 288.0 GB/s of dedicated GDDR6 bandwidth allow it to sustain far higher fill rates in DirectX 12 workloads. The 780M, with 768 shading units and system-shared memory, simply cannot keep pace.

Geekbench OpenCL shows an equally lopsided result. The RX 7600 scores 88,051, versus 18,602 for the 780M, a 78.9% gap. This test stresses raw compute throughput, and the numbers align with the FP32 specifications: the RX 7600 delivers 21.75 TFLOPS, while the 780M delivers 8.909 TFLOPS. The discrete card's 128 texture mapping units and 64 raster operations pipelines further widen the divide in parallel workloads.

The Vulkan test is the outlier. Here, the RX 7600 scores 34,401 and the 780M scores 33,683, a delta of just 2.1%. This is a remarkably tight result for an integrated GPU against a discrete card. The 780M's RDNA 3.0 architecture and 12 ray tracing cores likely contribute to its Vulkan efficiency, even though its raw FP32 throughput is less than half. The RX 7600 still wins, but the margin is small enough that users might not notice a difference in Vulkan-based applications at lower resolutions.

Across all three tests, the RX 7600 holds a decisive lead in two, and a narrow edge in the third. The 780M's best case is Vulkan, where it nearly matches the discrete card, but it cannot translate that efficiency into OpenCL or DirectX 12 victories.

Specification Differences

The two GPUs diverge sharply on memory architecture. The RX 7600 has 8 GB of GDDR6 memory on a 128-bit bus, delivering 288.0 GB/s of bandwidth. The 780M uses system-shared memory, with its bus width and bandwidth listed as "System Shared" and "System Dependent" respectively. This means the integrated part's memory performance depends entirely on the host system's RAM, while the discrete card has dedicated, high-speed VRAM.

Clock speeds also differ. The RX 7600 runs a base clock of 1720 MHz, a game clock of 2250 MHz, and a boost clock of 2655 MHz. The 780M starts at 800 MHz base and boosts to 2900 MHz. The 780M's higher boost clock does not compensate for its far smaller execution resources, but it does explain why the Vulkan gap is so narrow.

Power delivery is another major split. The RX 7600 has a 165 W TDP, requires a single 8-pin power connector, and is a dual-slot card with a suggested PSU of 450 W. The 780M is an integrated GPU with a 15 W TDP, no power connectors, and an IGP slot width. The 780M draws 150 W less at peak, making it far more suitable for low-power systems.

Physical dimensions differentiate them as well. The RX 7600 measures 204 mm in length and 115 mm in height. The 780M has no recorded dimensions, as it is embedded on the motherboard. The RX 7600 also offers dedicated display outputs, including 1x HDMI 2.1a and 3x DisplayPort 2.1, while the 780M's outputs are motherboard dependent.

Architecture Differences

Both GPUs use the RDNA 3.0 architecture, but they are built on different nodes and chips. The 780M uses the Phoenix chip on a 4 nm process at TSMC, with 25,390 million transistors on a 178 mm² die. The RX 7600 uses the Navi 33 chip on a 6 nm process, also at TSMC, with 13,300 million transistors on a 204 mm² die. The 780M packs more transistors into a smaller area, achieving a density of 142.6M per mm², versus 65.2M per mm² for the RX 7600.

Execution resources differ significantly. The 780M has 768 shading units, 48 texture mapping units, and 32 raster operations pipelines. The RX 7600 doubles or more: 2048 shading units, 128 TMUs, and 64 ROPs. Ray tracing cores also differ, with the 780M carrying 12 and the RX 7600 carrying 32. Neither GPU has tensor cores.

The 780M's output rates reflect its smaller footprint: 92.80 GPixel/s pixel rate and 139.2 GTexel/s texture rate. The RX 7600 reaches 169.9 GPixel/s and 339.8 GTexel/s. FP32 compute is 8.909 TFLOPS for the 780M and 21.75 TFLOPS for the RX 7600, with both offering 1:1 FP16 rates.

Generationally, the 780M belongs to the Navi III IGP (Phoenix) family, with a predecessor of Navi II IGP and a successor of Navi III IGP. The RX 7600 is part of the Radeon RX 7000 series, Navi III (RX 7000), with a predecessor of Navi II and a successor of Navi IV. The 780M released on 2024-01-30, while the RX 7600 released earlier on 2023-05-24. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, and both use PCIe 4.0 x8 interfaces.

The Verdict

The data directs different buyers to different products. The AMD Radeon RX 7600 is the pick for anyone prioritizing raw performance in DirectX 12 and OpenCL workloads. Its 79.2% lead in 3DMark Steel Nomad and 78.9% lead in Geekbench OpenCL make it the obvious choice for gaming and compute tasks. The 8 GB of GDDR6 memory and 288.0 GB/s bandwidth provide a dedicated memory pipeline that the 780M cannot match, and the 165 W TDP is a reasonable trade-off for desktop users with a 450 W PSU.

The AMD Radeon 780M serves a different role. Its 15 W TDP, integrated design, and system-shared memory make it suited for laptops or compact systems where power and space are constrained. Its Vulkan score of 33,683 is only 2.1% behind the RX 7600, indicating that for Vulkan-based applications, the integrated part can deliver near-discrete performance. Its 61st percentile ranking versus the RX 7600's 57th also suggests that, across the entire database, the 780M holds its own relative to other GPUs in ways the head-to-head tests do not capture.

Choose the RX 7600 for maximum throughput, dedicated VRAM, and consistent wins across all benchmark categories. Choose the 780M for low-power systems where Vulkan efficiency and integrated convenience matter more than raw compute. The recorded data does not support a single universal winner, but it clearly delineates their respective strengths.
