AMD Radeon RX 7600M XT vs NVIDIA GeForce GTX 780M Comparison

Head-to-Head Benchmarks

The database includes two directly comparable benchmark results for these mobile graphics processors, and the AMD Radeon RX 7600M XT dominates both. In Geekbench OpenCL, the AMD part scores 74,869 against 12,769 for the NVIDIA GeForce GTX 780M, a delta of 486.3%. That is not a marginal improvement; it is a generational leap expressed in raw compute throughput. The AMD GPU delivers roughly 5.9 times the OpenCL score of the older NVIDIA chip.

The second shared test, Geekbench Vulkan, tells a similar story but with a smaller margin. The RX 7600M XT records 27,793, while the GTX 780M manages 12,696. The delta here is 118.9%, meaning the AMD part is more than twice as fast in Vulkan workloads. Both wins go to the AMD Radeon RX 7600M XT, giving it a clean 2-0 record in head-to-head comparisons.

Looking at the broader average benchmark scores, the gap narrows but still favors the newer AMD part. The RX 7600M XT posts an average score of 12,710 across all recorded benchmarks, while the GTX 780M averages 11,261. That is a 12.9% advantage for AMD in overall performance. The percentile rankings reinforce this: the RX 7600M XT sits at the 52nd percentile of all GPUs in the database, while the GTX 780M sits at the 50th percentile. Despite the huge gap in specific compute tests, both cards land near the middle of the global distribution, which suggests the GTX 780M holds up reasonably well in certain legacy workloads.

The nearest rivals for the RX 7600M XT show how tightly clustered its average score is. The NVIDIA GeForce GTX 670 averages 12,773, which is only 0.5% higher than the AMD part. The NVIDIA Tesla K20Xm averages 12,625, putting it 0.7% behind. The NVIDIA GeForce GTX 590 and AMD Radeon Pro 455 both average 12,830 and 12,831 respectively, each about 0.9% ahead. In other words, the RX 7600M XT slots into a dense pack of mid-range performers from previous generations.

For the GTX 780M, its nearest rivals are similarly close. The AMD Radeon Pro WX 3200 averages 11,228, just 0.3% behind. The AMD FirePro W4300 averages 11,225, also 0.3% behind. The NVIDIA RTX PRO 6000 Blackwell Max-Q and RTX PRO 6000D Blackwell Max-Q both average 11,088, which is 1.6% behind the GTX 780M. This clustering suggests that the GTX 780M, despite its age, still competes with much newer entry-level workstation parts.

Architecture Differences

The architectural gap between these two GPUs is vast, reflecting nearly a decade of development. The AMD Radeon RX 7600M XT uses the Navi 33 chip built on RDNA 3.0 architecture, with the codename Hotpink Bonefish. It belongs to the Navi Mobile generation within the RX 7000M series. The process node is 6 nm at TSMC, and the die contains 13,300 million transistors on a 204 mm² area. That works out to a transistor density of 65.2 million per square millimeter.

The NVIDIA GeForce GTX 780M uses the GK104 chip built on the Kepler architecture from the GeForce 700M generation. It is manufactured on a 28 nm process at TSMC, with 3,540 million transistors on a 294 mm² die. The transistor density is just 12.0 million per square millimeter. The contrast is stark: the AMD chip packs more than 5.4 times the transistor density into a smaller die. This alone explains much of the performance difference.

Clock speeds also favor the AMD part dramatically. The RX 7600M XT has a base clock of 1280 MHz, a boost clock of 2469 MHz, and a game clock of 2023 MHz. The GTX 780M runs at a base of 771 MHz and a boost of 797 MHz. The AMD boost clock is more than three times the NVIDIA boost clock. Memory clocks differ as well: the RX 7600M XT runs its GDDR6 memory at 2250 MHz with 18 Gbps effective, while the GTX 780M runs GDDR5 at 1250 MHz with 5 Gbps effective.

The RX 7600M XT has 2048 shading units, 128 texture mapping units, 64 render output units, and 32 ray tracing cores. The GTX 780M has 1536 shading units, 128 TMUs, and 32 ROPs, with no ray tracing cores. The AMD part also supports DirectX 12 Ultimate (12_2), Vulkan 1.4, and OpenGL 4.6. The NVIDIA part supports DirectX 12 (11_0), Vulkan 1.2.175, and OpenGL 4.6. The API support difference matters for modern titles that leverage ray tracing and mesh shaders.

Where Each One Wins

The AMD Radeon RX 7600M XT wins in every measurable category in the head-to-head data. Its OpenCL score of 74,869 versus 12,769 for the GTX 780M indicates a massive advantage in general-purpose compute workloads, including physics simulations, video encoding, and machine learning inference. The Vulkan score of 27,793 versus 12,696 shows that modern graphics APIs heavily favor the AMD architecture.

The GTX 780M does have one unique benchmark result not shared with the AMD part: a Geekbench Metal score of 8,319. This is relevant only for Apple platforms, as Metal is Apple's graphics API. The AMD part has no recorded Metal score in the database, so comparisons in that specific API are not possible. For users on macOS with a GTX 780M, this is the only scenario where the NVIDIA part shows a measurable result.

For gaming at current titles, the RX 7600M XT is clearly the stronger choice. The DirectX 12 Ultimate support, ray tracing cores, and higher pixel and texture rates (158.0 GPixel/s and 316.0 GTexel/s versus 25.50 GPixel/s and 102.0 GTexel/s) make it suitable for modern workloads. The GTX 780M, with its DirectX 12 (11_0) support and no ray tracing, is limited to older titles or reduced settings in newer games.

For legacy software that relies on older DirectX versions, the PassMark results for the RX 7600M XT provide some insight: it scores 175 in DirectX 9, 137 in DirectX 11, 76 in DirectX 10, and 58 in DirectX 12. The GTX 780M has no recorded PassMark results in the database, so direct comparisons in those legacy APIs are unavailable. The RX 7600M XT also scores 13,907 in PassMark G3D and 7,140 in GPU compute, while the GTX 780M lacks those entries.

Specification Differences

The two GPUs differ in nearly every hardware specification. The AMD Radeon RX 7600M XT has 8 GB of GDDR6 memory on a 128-bit bus, yielding 288.0 GB/s of bandwidth. The NVIDIA GeForce GTX 780M has 4 GB of GDDR5 memory on a 256-bit bus, yielding 160.0 GB/s. Despite the narrower bus, the AMD part delivers 80% more memory bandwidth due to faster memory clocks.

The AMD part has 2048 shading units versus 1536 for NVIDIA. Both have 128 TMUs, but the AMD part has 64 ROPs versus 32 for NVIDIA. The AMD part includes 32 ray tracing cores; the NVIDIA part has none. The pixel rate for AMD is 158.0 GPixel/s versus 25.50 GPixel/s for NVIDIA. The texture rate is 316.0 GTexel/s versus 102.0 GTexel/s. The FP32 compute is 20.23 TFLOPS versus 2.448 TFLOPS. The AMD part also lists FP16 at 40.45 TFLOPS with a 2:1 ratio; the NVIDIA part has no FP16 data.

Power consumption is nearly identical despite the performance gap. The RX 7600M XT has a TDP of 120 W, while the GTX 780M has a TDP of 122 W. Both use no external power connectors. The form factors differ: the AMD part is an IGP (integrated graphics package), while the NVIDIA part is an MXM Module. The bus interface also differs: PCIe 4.0 x16 for AMD versus MXM-B (3.0) for NVIDIA.

The production status separates them clearly. The AMD part is Active, released on 2023-01-03, with a predecessor of Polaris Mobile and no successor. The NVIDIA part is End-of-life, released on 2013-05-10, with a predecessor of GeForce 600M and a successor of GeForce 800M. The AMD part belongs to the Radeon RX 7000 series; the NVIDIA part has no series designation in the database.
