AMD Radeon RX 7600 XT vs NVIDIA GeForce GTX 770 Comparison

Head-to-Head Benchmarks

The recorded data includes two direct cross-generation comparisons between the AMD Radeon RX 7600 XT and the NVIDIA GeForce GTX 770. In both tests, the AMD card dominates by a wide margin, reflecting the generational gap between a 2024 release and a 2013 release.

In Geekbench OpenCL, the AMD Radeon RX 7600 XT scores 92,426 points against the GTX 770's 15,707 points. That is a delta of 488.4% in favor of the AMD card. This is not a marginal improvement; the RX 7600 XT delivers nearly six times the raw compute throughput in this API. The OpenCL workload stresses general-purpose GPU compute, and the RX 7600 XT's 22.57 TFLOPS FP32 rate versus the GTX 770's 3.333 TFLOPS explains the magnitude of the gap, though the benchmark result itself is the primary evidence.

In Geekbench Vulkan, the RX 7600 XT scores 48,366 points, while the GTX 770 manages 19,166 points. The delta here is 152.4%, again favoring the AMD card. Vulkan is a lower-level API that benefits from modern architecture features, and the RX 7600 XT supports Vulkan 1.4, while the GTX 770 is limited to Vulkan 1.2.175. The AMD card also has 2,048 shading units compared to 1,536 on the GTX 770, along with a much higher boost clock of 2755 MHz versus 1085 MHz, all contributing to the decisive win.

The head-to-head record is 2 wins for the AMD Radeon RX 7600 XT and 0 wins for the NVIDIA GeForce GTX 770. There are no recorded tests where the older card outperforms the newer one. This is consistent with the average benchmark scores: the RX 7600 XT averages 17,083 points across its full benchmark suite, while the GTX 770 averages 14,747 points. The RX 7600 XT also sits at the 60th percentile among all GPUs in the database, whereas the GTX 770 sits at the 57th percentile.

However, it is notably the GTX 770's average is based on only three recorded benchmarks (Geekbench Metal, OpenCL, and Vulkan), while the RX 7600 XT has ten recorded benchmarks including multiple PassMark tests. The RX 7600 XT's PassMark G3D score of 17,132 and its DirectX 11 score of 167 suggest strong legacy API performance, while its DirectX 12 score of 65 and DirectX 10 score of 85 show modern and older API support respectively. The GTX 770 has no recorded PassMark scores in the database, so direct comparisons on those workloads are not possible.

Looking at the nearest rivals for each card provides additional context. The RX 7600 XT's closest competitor in the database is the NVIDIA GeForce RTX 3070, which averages 17,208 points, a delta of -0.7% meaning the RX 7600 XT is slightly behind. The RX 7600 XT is 0.3% ahead of the GTX 690, 0.4% ahead of the AMD Radeon HD 7970M, and 0.9% ahead of the NVIDIA Tesla M4. These are all very close margins, indicating that the RX 7600 XT sits in a tightly clustered performance band.

The GTX 770's nearest rivals show a different picture. It is 0.4% ahead of the AMD Radeon RX 5500 XT, 1.5% ahead of the NVIDIA Quadro M2000, but 2.1% behind the NVIDIA GeForce GTX 660 Ti and 2.2% behind the AMD Radeon Pro 560X. This suggests the GTX 770, despite its age, still competes with much newer entry-level cards in the database's average score metric, though its modern API support is limited.

Where Each One Wins

The AMD Radeon RX 7600 XT wins decisively in every recorded head-to-head benchmark. Its advantages are not limited to raw compute; the card also wins on memory capacity and bandwidth. The RX 7600 XT has 16 GB of GDDR6 memory on a 128-bit bus, delivering 288.0 GB/s of bandwidth. The GTX 770 has 2 GB of GDDR5 memory on a 256-bit bus, delivering 224.4 GB/s. While the GTX 770 has a wider bus, the RX 7600 XT's newer memory type and higher effective clock speed (18 Gbps versus 7 Gbps) give it a bandwidth advantage.

The RX 7600 XT also wins on pixel and texture throughput. Its pixel rate is 176.3 GPixel/s versus 34.72 GPixel/s on the GTX 770. Its texture rate is 352.6 GTexel/s versus 138.9 GTexel/s. These metrics indicate that the RX 7600 XT can handle higher resolutions and more detailed textures without bottlenecking, which is critical for modern games.

The GTX 770 has no recorded wins in any benchmark category. However, there are areas where it is not entirely obsolete. Its 256-bit memory bus is wider than the RX 7600 XT's 128-bit bus, though this does not translate to a performance win given the lower memory clocks. The GTX 770 also supports DirectX 12 (11_0) and OpenGL 4.6, though the RX 7600 XT supports DirectX 12 Ultimate (12_2) and Vulkan 1.4. For users constrained to older PCIe 3.0 systems, the GTX 770's PCIe 3.0 x16 interface may be more compatible with legacy motherboards, whereas the RX 7600 XT uses PCIe 4.0 x8.

In terms of use cases, the RX 7600 XT is clearly the choice for any workload that leverages modern APIs, high-resolution textures, or compute acceleration. Its 16 GB memory capacity is particularly notable for large datasets or high-resolution texture packs. The GTX 770 might still serve in a legacy system where the user only plays older DirectX 11 titles and does not need Vulkan 1.4 support, but the data shows no scenario where it outperforms the RX 7600 XT.

The Verdict

Based strictly on the recorded data, the AMD Radeon RX 7600 XT is the superior product in every measurable way. It wins both head-to-head benchmarks by deltas of 488.4% and 152.4%, has a higher average benchmark score (17,083 versus 14,747), and a higher percentile ranking (60th versus 57th). The RX 7600 XT also offers 16 GB of memory versus 2 GB, newer architecture (RDNA 3.0 versus Kepler), and a smaller process node (6 nm versus 28 nm).

The GTX 770, while still present in the database with a 57th percentile ranking, is end-of-life and cannot compete with the RX 7600 XT on any recorded metric. Its only potential advantage is its 256-bit memory bus and PCIe 3.0 x16 interface, which may suit very old systems, but the performance data does not favor it.

For a user building a new system or upgrading from a very old GPU, the RX 7600 XT is the clear choice based on benchmark results. For a user with a legacy system that only supports PCIe 3.0 and plays exclusively DirectX 11 titles, the GTX 770 might function, but the data shows it will be dramatically slower in any compute or Vulkan workload. The RX 7600 XT is the recommended pick for anyone prioritizing performance, modern API support, and future-proofing, as evidenced by its 16 GB memory and DirectX 12 Ultimate support.

Its launch MSRP is 399 USD.

The architectural differences are stark. The RX 7600 XT uses a smaller, denser process node (6 nm versus 28 nm) and has nearly four times the transistor count (13,300 million versus 3,540 million) on a smaller die (204 mm² versus 294 mm²). The RX 7600 XT also has a much higher boost clock (2755 MHz versus 1085 MHz) and significantly more memory (16 GB versus 2 GB).
