AMD Radeon RX 7600 vs NVIDIA GeForce GTX 770 Comparison

The AMD Radeon RX 7600 and NVIDIA GeForce GTX 770 are separated by a decade of GPU architecture, and the benchmark data reflects a generational chasm. In the two head-to-head tests available, the RX 7600 delivers a dominant performance, winning both matchups decisively. The most striking result is in Geekbench OpenCL, where the RX 7600 scores 88,051 against the GTX 770’s 15,707, a delta of 460.6%. The Vulkan test is less lopsided but still heavily favors the newer card, with the RX 7600 posting 34,401 versus 19,166, a 79.5% advantage. These are not incremental gains; they represent a complete overhaul in compute capability.

Head-to-Head Benchmarks

The Geekbench OpenCL result is the single largest performance gap between these two cards. The RX 7600’s score of 88,051 is more than five times higher than the GTX 770’s 15,707, translating to a 460.6% delta. This test stresses general-purpose compute workloads, and the data shows the RX 7600’s modern architecture is in a completely different league. The GTX 770, with its Kepler design, simply cannot keep pace in raw throughput, a conclusion reinforced by its FP32 rating of 3.333 TFLOPS compared to the RX 7600’s 21.75 TFLOPS.

In Geekbench Vulkan, the RX 7600 again takes the win, scoring 34,401 against the GTX 770’s 19,166. The 79.5% delta is substantial, though less extreme than the OpenCL gap. Vulkan is a low-level API that benefits from modern hardware features and driver optimization. The RX 7600’s support for Vulkan 1.4 and its RDNA 3.0 architecture likely contribute to this advantage. The GTX 770’s older Vulkan 1.2.175 support and Kepler-era hardware limit its ability to extract performance from this API.

The average benchmark scores tell a similar story. The RX 7600 holds an average score of 15,171 across its benchmark suite, while the GTX 770 averages 14,747. This places both cards in the 57th percentile of all GPUs, but the RX 7600’s nearest rivals include the NVIDIA GeForce RTX 3050 OEM (15,199, -0.2% delta) and the AMD Radeon 680M (15,270, -0.7% delta), showing it sits in a modern mid-range tier. The GTX 770, meanwhile, is bracketed by the AMD Radeon RX 5500 XT (14,692, 0.4% delta) and the NVIDIA Quadro M2000 (14,532, 1.5% delta), indicating it still competes with entry-level cards from several generations later.

Looking at the RX 7600’s individual benchmark results, it posts strong scores in Passmark G3D (16,634) and Passmark GPU Compute (8,790), while its Geekbench OpenCL score of 88,051 is a standout. The GTX 770 lacks these specific Passmark results, but its Geekbench Metal score of 9,369 is its only other data point beyond OpenCL and Vulkan. The absence of modern API benchmarks in the GTX 770’s results speaks to its age; it was not designed for the workloads that dominate today’s testing suites.

Architecture Differences

The architectural gap between these two GPUs is enormous. The RX 7600 uses the Navi 33 chip built on RDNA 3.0 architecture, fabricated on a 6 nm process at TSMC. It packs 13,300 million transistors into a 204 mm² die, yielding a transistor density of 65.2M per mm². The GTX 770, in contrast, uses the GK104 chip with Kepler architecture, built on a 28 nm process, also at TSMC. It contains 3,540 million transistors on a much larger 294 mm² die, giving a density of just 12.0M per mm². The process node shrink from 28 nm to 6 nm is the fundamental driver of the performance difference.

Memory configurations differ significantly. The RX 7600 comes with 8 GB of GDDR6 memory on a 128-bit bus, delivering 288.0 GB/s of bandwidth. The GTX 770 has only 2 GB of GDDR5 on a wider 256-bit bus, achieving 224.4 GB/s. While the GTX 770’s wider bus helped it in its era, the RX 7600’s faster memory and four times the capacity make it far more suitable for modern games and applications that demand large frame buffers.

Compute resources are also vastly different. The RX 7600 features 2,048 shading units, 128 TMUs, 64 ROPs, and 32 ray tracing cores. It achieves a pixel rate of 169.9 GPixel/s and a texture rate of 339.8 GTexel/s. The GTX 770 has 1,536 shading units, 128 TMUs, and 32 ROPs, with no ray tracing support. Its pixel rate is just 34.72 GPixel/s and texture rate is 138.9 GTexel/s. The RX 7600’s FP32 performance of 21.75 TFLOPS dwarfs the GTX 770’s 3.333 TFLOPS, and the RX 7600 also offers FP16 at 21.75 TFLOPS, a feature the GTX 770 lacks entirely.

Power and connectivity also reflect the generational shift. The RX 7600 has a TDP of 165 W and requires a single 8-pin power connector with a 450 W suggested PSU. The GTX 770 draws 230 W and needs both a 6-pin and an 8-pin connector, with a 550 W suggested PSU. The RX 7600 uses PCIe 4.0 x8, while the GTX 770 uses PCIe 3.0 x16. Display outputs differ as well: the RX 7600 offers 1x HDMI 2.1a and 3x DisplayPort 2.1, while the GTX 770 has 2x DVI, 1x HDMI 1.4a, and 1x DisplayPort 1.2.

The Verdict

The data leaves no ambiguity: the AMD Radeon RX 7600 is the superior GPU in nearly every measurable way. Its 460.6% lead in Geekbench OpenCL and 79.5% lead in Geekbench Vulkan demonstrate that it is not just faster, but categorically more capable in modern workloads. The RX 7600’s 8 GB of GDDR6 memory, 21.75 TFLOPS FP32 performance, and support for ray tracing make it a viable card for contemporary gaming and compute tasks. The GTX 770, with its 2 GB frame buffer, 3.333 TFLOPS, and lack of ray tracing, is a relic of an earlier era.

For users considering these two cards today, the choice is straightforward. The RX 7600 should be selected by anyone who needs current-generation features, higher memory capacity, or better performance in API-heavy applications. The GTX 770, while it still holds a 57th percentile ranking, is only relevant for legacy systems or very light workloads. Its nearest rivals include the RX 5500 XT and Quadro M2000, cards from a later generation that still outperform it in average score. The RX 7600, meanwhile, trades blows with the RTX 3050 OEM and Radeon 680M, placing it firmly in the modern entry-to-mid-range tier.

The GTX 770’s only advantages are its smaller die size in terms of absolute dimensions and its wider memory bus, but these do not compensate for the massive deficits in raw compute, memory capacity, and process efficiency. The RX 7600 is also more power-efficient, requiring 65 W less TDP and a lower suggested PSU. For anyone building or upgrading a system, the RX 7600 is the only rational choice based on benchmark data.
