AMD Radeon RX 7600S vs NVIDIA GeForce GTX 780 Comparison

Head-to-Head Benchmarks

The head-to-head data recorded in the database shows a decisive victory for the AMD Radeon RX 7600S in both compute and graphics API workloads. The RX 7600S wins 2 out of 2 direct comparisons, leaving the GeForce GTX 780 without a single win in the matched tests.

In Geekbench OpenCL, the AMD Radeon RX 7600S delivers a score of 68,012 compared to the GTX 780's 22,863. That represents a 66.4% advantage for the AMD part, a massive gap that reflects the generational leap in raw compute throughput. The RX 7600S is not merely faster, it is substantially ahead in a workload that stresses general-purpose GPU compute.

The Vulkan test tells a similar story. The RX 7600S posts 73,868 points against the GTX 780's 24,514, a 66.8% margin in favor of AMD. Vulkan performance is particularly relevant for modern game engines and cross-platform graphics workloads, and the data shows the newer RDNA 3.0 architecture handles this API with far greater efficiency.

Looking at the broader benchmark averages, the GTX 780 holds an average score of 19,164 across all recorded tests, while the RX 7600S averages 16,696. This is an interesting inversion: despite losing both head-to-head tests by large margins, the GTX 780 has a higher overall average. The reason lies in the test suites. The GTX 780 has results from Geekbench Metal, OpenCL, and Vulkan, while the RX 7600S includes several Passmark DirectX tests (9, 10, 11, and 12) plus 3DMark Steel Nomad DX12, which pull its average down. The Passmark DirectX scores for the RX 7600S are notably low: 74 in DX10, 140 in DX11, 65 in DX12, and 211 in DX9. These legacy API tests do not favor the RDNA 3.0 architecture, whereas the GTX 780's Kepler design was optimized for the older DirectX 11 era.

The percentile rankings reflect this mixed picture. The GTX 780 sits at the 64th percentile among all GPUs in the database, while the RX 7600S sits at the 60th percentile. Both are mid-pack performers in the grand scheme of all recorded graphics cards, but the GTX 780's position is buoyed by its strong Metal and Vulkan scores, while the RX 7600S's position is dragged down by its weak Passmark DX results.

In direct modern API comparisons, the RX 7600S is the clear winner. The OpenCL and Vulkan deltas of 66.4% and 66.8% respectively are not marginal improvements; they are dominant margins that any user would notice immediately. However, the GTX 780's higher average score and better percentile ranking show that the older card still holds its own in certain compute-oriented benchmarks, particularly Metal where it scores 10,114.

Architecture Differences

The architectural gap between these two GPUs spans a decade of semiconductor progress. The GTX 780 uses the GK110 chip built on TSMC's 28 nm process, while the RX 7600S uses the Navi 33 chip on TSMC's 6 nm node. The transistor counts tell the story of process advancement: the GTX 780 packs 7,080 million transistors on a 561 mm² die, yielding a density of 12.6 million transistors per square millimeter. The RX 7600S crams 13,300 million transistors onto just 204 mm², achieving a density of 65.2 million per square millimeter. That is a 5.2x increase in transistor density, enabled by the much smaller process node.

The GTX 780 is built on the Kepler architecture, which was designed for the GeForce 700 generation. It features 2,304 shading units, 192 texture mapping units, and 48 render output units. The RX 7600S, by contrast, uses the RDNA 3.0 architecture with 1,792 shading units, 112 TMUs, and 64 ROPs. Interestingly, the RX 7600S has fewer shading units and TMUs, yet achieves far higher performance in modern APIs. The reason is architectural efficiency: RDNA 3.0 delivers more work per clock than Kepler, and the RX 7600S runs at much higher clocks.

Clock speeds differ dramatically. The GTX 780 runs at a base of 863 MHz with a boost of 902 MHz. The RX 7600S runs at 1,500 MHz base and 2,200 MHz boost, with a game clock of 1,865 MHz. This clock advantage, combined with architectural improvements, explains the massive compute gap. The FP32 throughput of the RX 7600S is 15.77 TFLOPS versus the GTX 780's 4.156 TFLOPS, a 3.8x difference. The RX 7600S also supports FP16 at 31.54 TFLOPS (2:1 ratio), while the GTX 780 has no recorded FP16 capability.

Memory subsystems also diverge. The GTX 780 uses 3 GB of GDDR5 on a 384-bit bus, delivering 288.4 GB/s of bandwidth. The RX 7600S uses 8 GB of GDDR6 on a 128-bit bus, delivering 256.0 GB/s. Despite the narrower bus, the faster GDDR6 memory keeps bandwidth competitive. The RX 7600S also features 28 ray tracing cores, while the GTX 780 has none. This is a critical feature difference for modern games that support ray tracing effects.

The RX 7600S supports DirectX 12 Ultimate (12_2), while the GTX 780 only supports DirectX 12 (11_0). Both support OpenGL 4.6, but the Vulkan support differs: the RX 7600S supports Vulkan 1.4, while the GTX 780 supports Vulkan 1.2.175. The RX 7600S also uses PCIe 4.0 x16, doubling the bus bandwidth of the GTX 780's PCIe 3.0 x16.

Power consumption is a stark differentiator. The GTX 780 has a TDP of 250 W and requires both a 6-pin and 8-pin power connector, along with a 600 W suggested power supply. The RX 7600S has a TDP of just 75 W, uses no power connectors (it is an integrated graphics processor, or IGP), and has no suggested PSU requirement. This makes the RX 7600S extremely power-efficient by comparison, consuming only 30% of the GTX 780's power budget.

The GTX 780 is a dual-slot card measuring 267 mm in length, 111 mm in height, and 38 mm in width, with display outputs of 2x DVI, 1x HDMI 1.4a, and 1x DisplayPort 1.2. The RX 7600S is an IGP with no recorded dimensions and has display outputs that are portable device dependent.

The Verdict

The data paints a clear picture for different use cases. For modern compute and graphics workloads, the AMD Radeon RX 7600S is the superior choice. Its 66.4% lead in OpenCL and 66.8% lead in Vulkan are dominant margins that directly translate to better performance in contemporary applications and games. The RX 7600S also brings ray tracing support, DirectX 12 Ultimate, and Vulkan 1.4, features that the GTX 780 simply cannot offer.

For users working with Metal-based workloads, the GTX 780's score of 10,114 in Geekbench Metal is a notable data point, though the RX 7600S does not have a recorded Metal score for direct comparison. The GTX 780's higher average benchmark score and better percentile ranking (64th versus 60th) suggest it remains competitive in certain legacy or API-specific scenarios.

The power efficiency argument heavily favors the RX 7600S. At 75 W TDP versus 250 W, the AMD part delivers significantly more performance per watt. This is critical for laptop implementations, where the RX 7600S's IGP form factor is designed for mobility, while the GTX 780's dual-slot, 267 mm card is a desktop-only solution.

The GTX 780's launch MSRP was 649 USD, and it is now end-of-life. The RX 7600S has no recorded launch MSRP and remains in active production. For anyone building a new system, the RX 7600S is the rational choice based on benchmark data alone. For those constrained to older platforms or requiring specific legacy API support, the GTX 780 still holds value, but its days are numbered.
