AMD Radeon RX 7600 vs NVIDIA GeForce GTX 660 Ti Comparison

FAQ

Q: How does the AMD Radeon RX 7600 compare to the NVIDIA GeForce GTX 660 Ti in average benchmark score?

A: The RX 7600 has an average benchmark score of 15171, while the GTX 660 Ti scores 15063. That is a 0.7% gap in favor of the RX 7600, according to the deltaPct values in the nearestRivals data.

Q: Which card wins in Geekbench OpenCL performance?

A: The RX 7600 dominates with a score of 88051 versus 15113 for the GTX 660 Ti. The deltaPct is 482.6%, meaning the RX 7600 is nearly five times faster in this compute workload.

Q: What about Vulkan performance in Geekbench?

A: The RX 7600 scores 34401, while the GTX 660 Ti scores 15012. That gives the RX 7600 a 129.2% advantage, more than double the performance of the older card.

Q: Are both cards in the same performance percentile?

A: Yes, both cards sit at the 57th percentile among all GPUs. Despite the massive generational gap, their average benchmark scores place them in the same percentile band, which is unusual given the architectural differences.

Q: Which card has more memory and bandwidth?

A: The RX 7600 has 8 GB of GDDR6 memory on a 128-bit bus, yielding 288.0 GB/s bandwidth. The GTX 660 Ti has 2 GB of GDDR5 on a 192-bit bus, providing 144.2 GB/s. The RX 7600 doubles the capacity and doubles the bandwidth.

Q: What is the production status of each card?

A: The RX 7600 is listed as "Active" production, released on 2023-05-24. The GTX 660 Ti is "End-of-life", released on 2012-08-15. The RX 7600 is a current product, while the GTX 660 Ti is a legacy part.

The Verdict

The data paints a clear picture: the AMD Radeon RX 7600 is the card to buy for anyone building or upgrading a system today. Its average benchmark score of 15171 edges out the GTX 660 Ti's 15063 by a 0.7% margin in aggregate, but that headline number hides the real story. In the two head-to-head tests available, the RX 7600 wins both decisively — 482.6% ahead in Geekbench OpenCL and 129.2% ahead in Geekbench Vulkan. Those are not incremental gains; they are generational leaps.

The GTX 660 Ti, despite being end-of-life and released over a decade earlier, still holds its own in raw average score. That reflects its original design. But the data also shows it lacks modern API support — DirectX 12 (11_0) versus the RX 7600's DirectX 12 Ultimate (12_2) — and its 2 GB memory capacity is a hard ceiling for contemporary workloads. The RX 7600 offers 8 GB, 288.0 GB/s bandwidth, and 21.75 TFLOPS FP32 compute. The GTX 660 Ti manages 2.634 TFLOPS FP32. There is no scenario where the older card is the rational pick for a new build.

Pick the RX 7600 if you want a current, active product with modern features and a clear performance path. Pick the GTX 660 Ti only if you are dealing with legacy hardware, retro systems, or a very specific compatibility requirement — the data does not support it as a competitive choice otherwise.

Head-to-Head Benchmarks

The head-to-head data is sparse but unambiguous. There are two benchmark entries, and the RX 7600 wins both.

In Geekbench OpenCL, the RX 7600 scores 88051 against the GTX 660 Ti's 15113. The deltaPct is 482.6%. That is a massive compute advantage, driven largely by the RX 7600's 2048 shading units, 21.75 TFLOPS FP32 throughput, and 6 nm process node versus the GTX 660 Ti's 1344 shading units and 2.634 TFLOPS. For any OpenCL-accelerated workload — rendering, physics simulation, or GPGPU tasks — the RX 7600 is in a different league.

In Geekbench Vulkan, the RX 7600 scores 34401 versus 15012 for the GTX 660 Ti. The deltaPct is 129.2%. This is a smaller but still dominant margin. Vulkan's lower-level API benefits from the RX 7600's RDNA 3.0 architecture and DirectX 12 Ultimate (12_2) feature set, while the GTX 660 Ti's Kepler architecture supports Vulkan 1.2.175 — functional, but far less efficient.

The aggregate score tells a different story. The RX 7600's average benchmark score of 15171 is only 0.7% higher than the GTX 660 Ti's 15063. That seems contradictory given the head-to-head results. The explanation lies in the benchmark mix. The RX 7600 has ten benchmark entries, including PassMark DirectX 9, 10, 11, and 12 tests, plus a G2D score of 984 and a G3D score of 16634. The GTX 660 Ti only has two entries, both Geekbench tests. The average is skewed by the differing test suites, so the head-to-head results are the more reliable comparison for direct performance differences.

Architecture Differences

The architectural divide is fundamental. The RX 7600 is built on AMD's RDNA 3.0 architecture, codenamed "Hotpink Bonefish", part of the Navi III (RX 7000) generation. The chip is Navi 33. RDNA 3.0 is a modern, chiplet-inspired design that emphasizes efficiency and high clock speeds, as evidenced by the 2655 MHz boost clock and 6 nm process node.

The GTX 660 Ti is based on NVIDIA's Kepler architecture, using the GK104 chip from the GeForce 600 generation. Kepler was designed for the 28 nm era, with a lower clock ceiling (980 MHz boost) and a significantly simpler compute layout. The GTX 660 Ti has no dedicated ray tracing cores, while the RX 7600 includes 32 RT cores. The RX 7600 also supports DirectX 12 Ultimate (12_2), bringing features like mesh shaders and variable rate shading, while the GTX 660 Ti is limited to DirectX 12 (11_0).

Memory architecture differs too. The RX 7600 uses a 128-bit bus with GDDR6, achieving 288.0 GB/s. The GTX 660 Ti uses a wider 192-bit bus with GDDR5 but only reaches 144.2 GB/s — half the bandwidth. The RX 7600's smaller bus is compensated by faster memory clocks (18 Gbps effective vs 6 Gbps effective). Transistor density is another differentiator: 65.2M per mm² on the RX 7600 versus 12.0M per mm² on the GTX 660 Ti, reflecting the massive process node advantage.

The RX 7600 also supports newer display outputs — HDMI 2.1a and DisplayPort 2.1 — versus the GTX 660 Ti's DVI and HDMI 1.4a. This matters for high refresh rate monitors and modern VR headsets. The RX 7600's FP16 throughput matches its FP32 at 21.75 TFLOPS (1:1), while the GTX 660 Ti has no listed FP16 capability.

Where Each One Wins

The RX 7600 wins in every measurable category from the data. In the two head-to-head benchmarks, it takes both — Geekbench OpenCL by 482.6% and Geekbench Vulkan by 129.2%. Its average benchmark score of 15171 is higher than the GTX 660 Ti's 15063, and it holds a 0.7% deltaPct advantage in the nearestRivals comparison. The RX 7600 also wins on memory capacity (8 GB vs 2 GB), bandwidth (288.0 GB/s vs 144.2 GB/s), and compute throughput (21.75 TFLOPS vs 2.634 TFLOPS). For any modern workload — gaming at 1080p or 1440p, content creation, or compute tasks — the RX 7600 is the clear choice.

The GTX 660 Ti has no benchmark wins in this data set. Its only redeeming qualities are historical. It matches the RX 7600 in percentile (57th) and has a lower TDP (150 W vs 165 W), though both cards recommend a 450 W PSU. The GTX 660 Ti also supports PCIe 3.0 x16, which may be relevant for very old motherboards, but that is a compatibility niche rather than a performance advantage. Its 2 GB memory is insufficient for modern textures, and its DirectX 12 (11_0) support is outdated. In short, the GTX 660 Ti wins nowhere in this comparison — it is a legacy part that the RX 7600 surpasses in every benchmark and specification field where data exists.
