AMD Radeon RX 7600M XT vs NVIDIA GeForce GTX 770 Comparison

The GeForce GTX 770 and the Radeon RX 7600M XT sit at opposite ends of the GPU timeline, separated by a decade of architecture evolution. The GTX 770 is a Kepler-era desktop card from 2013, while the RX 7600M XT is a 2023 mobile part built on RDNA 3.0. Their benchmark scores reflect that gap: the database records an average benchmark score of 14,747 for the GTX 770 against 12,710 for the RX 7600M XT. Yet the head-to-head results tell a more nuanced story, with the AMD card winning both shared tests by wide margins. This comparison highlights how synthetic averages can mask dramatic differences in specific workloads.

Where Each One Wins

The GTX 770 claims the higher overall average benchmark score, 14,747 versus 12,710 for the RX 7600M XT. That places the NVIDIA card at the 57th percentile of all GPUs in the database, while the AMD part sits at the 52nd percentile. The GTX 770’s edge comes from its consistency across older API tests, where its Kepler architecture still holds its own. Its nearest rivals include the GeForce GTX 660 Ti (average score 15,063, delta of -2.1%) and the Radeon Pro 560X (average score 15,082, delta of -2.2%). The RX 7600M XT, by contrast, sits just behind the GeForce GTX 670 (average score 12,773, delta of -0.5%) and ahead of the Tesla K20Xm (average score 12,625, delta of 0.7%). The AMD mobile GPU’s lower average is not a sign of weakness in modern workloads; it reflects a different benchmark mix.

Where the RX 7600M XT wins decisively is in compute-heavy and API-modern scenarios. In the two head-to-head tests recorded, it dominates. The Geekbench OpenCL score for the RX 7600M XT is 74,869, a 79% advantage over the GTX 770’s 15,707. The Geekbench Vulkan score is 27,793 versus 19,166, a 31% lead. These are not marginal wins; they indicate the AMD card is in a different performance class for general-purpose compute and modern graphics APIs. The GTX 770’s wins, if any, are not captured in the shared head-to-head list, as it records zero wins in that category. The RX 7600M XT takes both.

For gaming, the RX 7600M XT shows strength in the PassMark suite: DirectX 9 score of 175, DirectX 11 score of 137, and DirectX 10 score of 76. Its DirectX 12 score is 58, and the G3D score is 13,907. The GTX 770 has no PassMark entries in the database, so direct gaming comparisons are limited to the Geekbench Vulkan result, where the AMD card leads by 31%. The data suggests the RX 7600M XT is the better choice for anyone running Vulkan or OpenCL workloads, while the GTX 770’s higher average makes it a more balanced legacy performer.

Architecture Differences

The architectural gap is vast. The GTX 770 uses the GK104 chip on NVIDIA’s Kepler architecture, fabricated on a 28 nm process at TSMC. It packs 3,540 million transistors into a 294 mm² die, for a transistor density of 12.0 million per square millimeter. The RX 7600M XT uses the Navi 33 chip on AMD’s RDNA 3.0 architecture, codenamed Hotpink Bonefish, built on a 6 nm process, also at TSMC. That chip contains 13,300 million transistors on a smaller 204 mm² die, achieving a density of 65.2 million per square millimeter. The density difference is a factor of over five, illustrating how far process technology advanced in a decade.

The RX 7600M XT’s compute resources are substantially larger. It has 2,048 shading units, 128 texture mapping units, and 64 ROPs. The GTX 770 has 1,536 shading units, 128 TMUs, and only 32 ROPs. The AMD card also includes 32 ray tracing cores, a feature entirely absent from the Kepler design. The pixel rate reflects this: the RX 7600M XT hits 158.0 GPixel/s, while the GTX 770 manages 34.72 GPixel/s. Texture rate is similarly lopsided: 316.0 GTexel/s versus 138.9 GTexel/s.

Clock speeds tell part of the story. The GTX 770 runs a 1046 MHz base and 1085 MHz boost, with memory clocked at 1753 MHz (7 Gbps effective). The RX 7600M XT has a 1280 MHz base, a 2469 MHz boost, and a game clock of 2023 MHz. Its memory runs at 2250 MHz (18 Gbps effective). The AMD card’s FP32 throughput is 20.23 TFLOPS, compared to 3.333 TFLOPS for the NVIDIA card. FP16 on the RX 7600M XT reaches 40.45 TFLOPS (2:1 ratio); the GTX 770 has no listed FP16 figure.

Memory capacity and bandwidth also favor the newer card. The RX 7600M XT has 8 GB of GDDR6 on a 128-bit bus, yielding 288.0 GB/s of bandwidth. The GTX 770 has 2 GB of GDDR5 on a 256-bit bus, giving 224.4 GB/s. While the bus is narrower on the AMD card, the faster memory type and higher effective speed produce more bandwidth. The GTX 770’s power draw is 230 W with a recommended 550 W PSU, while the RX 7600M XT is a 120 W mobile part with no power connector requirements. The NVIDIA card is dual-slot and 267 mm long; the AMD card is an integrated graphics package (IGP) with portable-device-dependent outputs.

API support differs notably. The RX 7600M XT supports DirectX 12 Ultimate (12_2), while the GTX 770 only reaches DirectX 12 (11_0). Both support OpenGL 4.6. Vulkan support is 1.4 on the AMD card versus 1.2.175 on the NVIDIA card. The GTX 770 offers display outputs of 2x DVI, 1x HDMI 1.4a, and 1x DisplayPort 1.2; the RX 7600M XT is portable-device dependent. The GTX 770 was released on May 29, 2013, with a launch MSRP of 399 USD. The RX 7600M XT launched January 3, 2023, with no MSRP listed. The GTX 770 is end-of-life, succeeded by the GeForce 900 series; the RX 7600M XT is active, succeeding Polaris Mobile.

Head-to-Head Benchmarks

The database records two shared benchmarks between these GPUs. In Geekbench OpenCL, the RX 7600M XT scores 74,869 against the GTX 770’s 15,707. That is a delta of -79% from the AMD card’s perspective, meaning the NVIDIA part trails by roughly four-fifths. This is the single largest performance gap in the comparison. OpenCL is a general-purpose compute API, and the RDNA 3.0 architecture’s higher FP32 throughput (20.23 TFLOPS versus 3.333 TFLOPS) explains the result. The GTX 770’s older Kepler design was never optimized for this kind of raw compute.

In Geekbench Vulkan, the RX 7600M XT scores 27,793 versus 19,166 for the GTX 770. The delta is -31%, a smaller but still decisive margin. Vulkan is a modern graphics API that benefits from the RX 7600M XT’s DirectX 12 Ultimate feature set and ray tracing cores. The GTX 770’s Vulkan support is present (1.2.175) but its hardware was designed for DirectX 11-era workloads. The 31% gap in Vulkan is consistent with the architectural differences: more shading units, higher clocks, and newer memory all contribute.

The head-to-head record is 2 wins for the RX 7600M XT and 0 for the GTX 770. No other shared tests exist in the database. The GTX 770’s average benchmark score of 14,747 comes from its Geekbench Metal score of 9,369, OpenCL score of 15,707, and Vulkan score of 19,166. The RX 7600M XT’s average of 12,710 is dragged down by low PassMark DirectX scores (58 for DirectX 12, 76 for DirectX 10) but boosted by its 13,907 PassMark G3D score and 74,869 OpenCL result. The averages are not directly comparable because the test suites differ.

The Verdict

The data points to a clear split by workload era. For legacy applications and synthetic averages, the GTX 770 holds a higher percentile rank (57 versus 52) and a higher average score (14,747 versus 12,710). Its nearest rivals, the GeForce GTX 660 Ti and Radeon Pro 560X, sit within 2.2% of its average, indicating it remains competitive among older desktop parts. If the workload is confined to DirectX 11-era games or older OpenGL titles, the GTX 770’s 230 W desktop design with 2 GB of GDDR5 can still deliver, though its 3.333 TFLOPS FP32 is modest.

For any modern task, the RX 7600M XT is the only rational choice. Its 74,869 OpenCL score is nearly five times the GTX 770’s, and its 27,793 Vulkan score beats the NVIDIA card by 31%. The 8 GB memory capacity, 288.0 GB/s bandwidth, and 20.23 TFLOPS FP32 make it far more capable for compute, ray tracing, and DirectX 12 Ultimate workloads. The 120 W power draw, with no external power connectors, also makes it suitable for portable devices, unlike the GTX 770’s dual-slot, 267 mm, 230 W design.

The RX 7600M XT’s lower average score is misleading. Its PassMark DirectX 12 score of 58 and DirectX 10 score of 76 are outliers that pull the average down, but its G3D score of 13,907 and OpenCL score of 74,869 reflect real strength. The GTX 770’s average is buoyed by its Metal score of 9,369, which the AMD card does not contest. Buyers should not choose based on the overall average alone.

The verdict: pick the RX 7600M XT for anything involving Vulkan, OpenCL, modern DirectX, or ray tracing. Pick the GTX 770 only if the software stack is fixed to legacy APIs and the higher percentile ranking matters more than raw compute. The GTX 770 is end-of-life, while the RX 7600M XT is active and built on a 6 nm process with 13,300 million transistors. The decade of architectural progress is not a tie; it is a decisive advantage for the AMD mobile GPU.
