AMD Radeon RX 7600M XT vs NVIDIA GeForce GTX 670 Comparison

The NVIDIA GeForce GTX 670 and AMD Radeon RX 7600M XT occupy the same percentile rank (52nd) among all GPUs, yet their average benchmark scores tell a story of near-parity with vastly different underlying technologies. The GTX 670 averages 12,773 points, while the RX 7600M XT trails by a razor-thin 0.5% at 12,710 points. This statistical dead heat is remarkable given the eleven-year gap between their release dates, but it masks dramatic divergences in how each card performs across specific workloads.

Head-to-Head Benchmarks

The head-to-head data reveals a clear pattern: the AMD Radeon RX 7600M XT wins both available comparisons, but the margin is not uniform. In Geekbench OpenCL, the RX 7600M XT posts 74,869 points against the GTX 670’s 15,341, a staggering 79.5% advantage. This is not a marginal victory—it is a generational obliteration in compute-heavy workloads. The OpenCL test stresses raw parallel processing, and the RX 7600M XT’s RDNA 3.0 architecture with 2,048 shading units simply overwhelms the older Kepler design.

The Vulkan result narrows considerably. The RX 7600M XT scores 27,793 versus 15,553 for the GTX 670, a 44% lead. While still a decisive win, this smaller gap hints that the GTX 670’s older driver optimizations or architectural strengths in certain rendering paths keep it more competitive in graphics-centric APIs. The deltaPct values in the nearestRivals data confirm this asymmetry: the RX 7600M XT is listed as 0.5% slower overall than the GTX 670, yet in individual tests it leads by double-digit percentages. This suggests the average score is pulled down by the RX 7600M XT’s weaker showings in other benchmark suites not part of the head-to-head comparison.

Notably, the GTX 670 wins zero head-to-head tests. The winsA field is 0, and winsB is 2. This is a clean sweep, but the aggregate benchmarks show the two cards are effectively peers in overall performance. The implication is that the GTX 670’s strengths lie in legacy or specific workloads not captured in these two comparisons, while the RX 7600M XT dominates modern compute and graphics APIs.

Architecture Differences

The architectural chasm between these two GPUs is cavernous. The GTX 670 uses the GK104 chip on a 28 nm TSMC process, packing 3,540 million transistors into a 294 mm² die. The RX 7600M XT employs the Navi 33 chip on a 6 nm TSMC node, fitting 13,300 million transistors into just 204 mm². This yields a transistor density of 65.2M per mm² for the AMD part versus 12.0M per mm² for the NVIDIA—a 5.4x density advantage that explains how AMD crams nearly four times the transistors into a smaller footprint.

Clock speeds tell a similar story of generational progress. The GTX 670 runs a 915 MHz base and 980 MHz boost, while the RX 7600M XT operates at 1,280 MHz base, 2,023 MHz game clock, and 2,469 MHz boost. The AMD card’s boost clock is 2.5x higher than the NVIDIA’s base clock. Memory follows suit: the GTX 670 uses 2 GB of GDDR5 on a 256-bit bus for 192.3 GB/s bandwidth, whereas the RX 7600M XT has 8 GB of GDDR6 on a 128-bit bus delivering 288.0 GB/s. Despite half the bus width, the AMD card achieves 50% more bandwidth thanks to faster memory.

Compute resources diverge sharply. The GTX 670 has 1,344 shading units, 112 TMUs, and 32 ROPs. The RX 7600M XT has 2,048 shading units, 128 TMUs, and 64 ROPs. More tellingly, the RX 7600M XT includes 32 ray tracing cores, a feature entirely absent from the GTX 670. The FP32 throughput is 2.634 TFLOPS for the GTX 670 versus 20.23 TFLOPS for the RX 7600M XT—a 7.7x difference. The AMD card also supports FP16 at 40.45 TFLOPS, while the GTX 670 lists no FP16 capability.

The Verdict

The data points to a paradox: the RX 7600M XT is the objectively superior piece of hardware in nearly every measurable specification, yet the aggregate performance scores say these two cards are functional equals. The RX 7600M XT wins both head-to-head tests decisively, offers 4x the memory, 7.7x the FP32 throughput, ray tracing support, a smaller die, lower power draw, and newer API support. The GTX 670’s only advantages are its desktop form factor with discrete display outputs and its established 399 USD launch MSRP.

For a user prioritizing raw compute performance in OpenCL or Vulkan workloads, the RX 7600M XT is the clear choice—its 79.5% OpenCL lead is insurmountable. For someone needing a traditional desktop card with DVI, HDMI, and DisplayPort outputs, the GTX 670 provides that connectivity while matching the overall benchmark average. The RX 7600M XT’s "Portable Device Dependent" display outputs mean it is not a drop-in desktop replacement, but its IGP form factor and lack of power connectors make it ideal for laptops. The GTX 670’s End-of-life status and 170 W TDP versus the RX 7600M XT’s Active status and 120 W TDP further tilt the long-term viability argument toward AMD.

Where Each One Wins

The RX 7600M XT wins in every direct computational comparison. Geekbench OpenCL and Vulkan both favor AMD by wide margins—79.5% and 44%, respectively. Its 32 ray tracing cores provide hardware acceleration that the GTX 670 cannot emulate. The 8 GB memory capacity is four times larger, which matters for modern games and large datasets. The 20.23 TFLOPS FP32 throughput and 316.0 GTexel/s texture rate are 7.7x and 2.9x higher, respectively, making it the choice for compute-heavy applications. The 158.0 GPixel/s pixel rate is 5.8x the GTX 670’s 27.44 GPixel/s, indicating faster fill-rate-bound rendering. The PCIe 4.0 x16 interface doubles the bandwidth headroom of the GTX 670’s PCIe 3.0.

The GTX 670 wins in legacy compatibility and desktop integration. Its 256-bit memory bus, while narrower in bandwidth, offers a wider path that can be advantageous in certain access patterns. The 2x DVI, 1x HDMI 1.4a, and 1x DisplayPort 1.2 outputs are concrete and immediately usable, unlike the RX 7600M XT’s portable-device-dependent scheme. The dual-slot design with 2x 6-pin power connectors is a standard desktop configuration, whereas the RX 7600M XT has no physical dimensions listed and uses no power connectors. The GTX 670’s 399 USD launch MSRP is the only pricing data available, and its 12 (11_0) DirectX support, while older, maintains compatibility with a vast library of applications. The average benchmark score of 12,773 edges out the RX 7600M XT by 63 points, meaning in mixed workloads, the GTX 670 can still hold its own despite being a decade older.
