AMD Radeon 680M vs AMD Radeon RX 7600 XT Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive sweep for the AMD Radeon RX 7600 XT across all three shared benchmark tests. In 3DMark Steel Nomad DX12, the RX 7600 XT scores 2348 against the Radeon 680M's 378, a delta of 521.2%. This is the largest gap in the comparison, indicating a fundamental difference in sustained rendering performance under modern DirectX 12 workloads. The Geekbench OpenCL result follows a similar pattern: the RX 7600 XT posts 92426, while the Radeon 680M manages 23468, a 293.8% advantage. This test stresses general-purpose compute throughput, where the dedicated card's higher shader count and memory bandwidth become decisive.

The narrowest margin appears in Geekbench Vulkan, where the RX 7600 XT scores 48366 versus 21965 for the Radeon 680M, a 120.2% lead. While still a substantial victory, the smaller delta suggests that the Vulkan API path partially mitigates the hardware gap, possibly due to driver efficiency or the integrated part's ability to leverage system memory more effectively in certain workloads. Overall, the RX 7600 XT wins all three head-to-head tests, with zero wins for the Radeon 680M. The average benchmark score reinforces this hierarchy: the RX 7600 XT sits at 17083, while the Radeon 680M averages 15270.

Context from the nearest rivals clarifies the positioning. The RX 7600 XT's average score places it 0.3% above the NVIDIA GeForce GTX 690 (17037) and 0.9% above the NVIDIA Tesla M4 (16932), while trailing the GeForce RTX 3070 by just 0.7% (17208). This means the RX 7600 XT operates in the same performance band as a last-generation flagship dual-GPU card and a modern mid-range RTX card. The Radeon 680M, by contrast, sits 0.1% below both the GeForce GTX 580 (15283) and the GeForce RTX 2060 (15290), and 0.5% above the RTX 3050 OEM (15199). The 680M's closest rival in the database is the AMD Radeon RX 7600, which scores 15171, a 0.7% deficit for the 680M. This places the integrated graphics squarely in the territory of older discrete GPUs, not modern dedicated cards.

Architecture Differences

The two AMD parts share a manufacturer and foundry, both using TSMC's 6 nm process, but diverge sharply in architecture generation and design intent. The RX 7600 XT is built on RDNA 3.0 with the Navi 33 chip, codenamed Hotpink Bonefish, belonging to the Navi III (RX 7000) generation. The Radeon 680M uses RDNA 2.0 with the Rembrandt+ chip, listed as Navi II IGP for Rembrandt Mobile. This generational gap explains the efficiency and feature differences: RDNA 3.0 introduces improved shader reordering and a different compute unit layout compared to RDNA 2.0.

Transistor counts are close but not identical: the RX 7600 XT packs 13,300 million transistors on a 204 mm² die, yielding a density of 65.2M per mm². The Radeon 680M has 13,100 million transistors on a slightly larger 208 mm² die, giving 63.0M per mm². The RX 7600 XT achieves higher density on a smaller die, consistent with its newer architecture. Clock behavior differs notably: the RX 7600 XT has a base of 1980 MHz, a boost of 2755 MHz, and a game clock of 2470 MHz, while the Radeon 680M runs a higher base of 2000 MHz but a lower boost of 2200 MHz, with no game clock listed. The 680M's higher base clock reflects its fixed-function integration into a mobile APU, but its boost ceiling is far lower.

Compute resources show a stark divide. The RX 7600 XT features 2048 shading units, 128 texture mapping units, 64 ROPs, and 32 ray accelerators. The Radeon 680M has 768 shading units, 48 TMUs, 32 ROPs, and 12 ray accelerators. This means the RX 7600 XT has roughly 2.7 times the shading units, 2.7 times the TMUs, twice the ROPs, and 2.7 times the ray accelerators. The FP32 throughput tells the story: 22.57 TFLOPS for the RX 7600 XT versus 3.379 TFLOPS for the Radeon 680M. The FP16 rates also differ in ratio: the RX 7600 XT offers 22.57 TFLOPS at a 1:1 ratio with FP32, while the 680M provides 6.758 TFLOPS at a 2:1 ratio, indicating the integrated part halves its FP16 throughput relative to FP32.

Memory architecture is fundamentally different. The RX 7600 XT uses 16 GB of GDDR6 on a 128-bit bus, delivering 288.0 GB/s bandwidth. The Radeon 680M relies on System Shared memory, with bandwidth listed as System Dependent. This means the 680M's performance scales with the host system's RAM speed and configuration, an unpredictable variable. The RX 7600 XT's dedicated memory eliminates that dependency, providing consistent bandwidth for texture-heavy workloads.

Where Each One Wins

The AMD Radeon RX 7600 XT wins every benchmark where both parts are measured. Its 521.2% lead in 3DMark Steel Nomad DX12 makes it the clear choice for modern DirectX 12 gaming, particularly at higher resolutions or with ray tracing enabled, given its 32 ray accelerators versus 12. The 293.8% OpenCL advantage points to strong compute workloads such as rendering, simulation, or machine learning inference. The 120.2% Vulkan lead, while smaller, still means the RX 7600 XT is preferable for Vulkan-based titles and cross-platform engines. For any task requiring consistent memory bandwidth, the 288.0 GB/s dedicated GDDR6 is categorically superior to the 680M's system-dependent shared memory.

The AMD Radeon 680M wins in the categories of power consumption and physical footprint. Its 50 W TDP versus 190 W means it requires no power connector and no PSU recommendation, making it suitable for thin-and-light laptops or low-power SFF builds. The IGP slot width and lack of add-in card dimensions mean it occupies no expansion slot. For portable devices, the display outputs are device-dependent, allowing flexible integration. The 680M's higher base clock of 2000 MHz versus 1980 MHz suggests it can start workloads quickly, but the boost ceiling of 2200 MHz limits sustained performance. Its 12 ray accelerators and 6.758 TFLOPS FP16 (2:1) still provide capable integrated graphics for casual gaming or light creative work, but the data does not support any performance win over the RX 7600 XT.

The Verdict

The choice between these two GPUs depends entirely on form factor and power budget, not on performance, because the benchmark data shows no scenario where the Radeon 680M competes with the RX 7600 XT. The RX 7600 XT is the appropriate selection for a desktop system with a 450 W PSU, a PCIe 4.0 x8 slot, and room for a dual-slot card measuring 204 mm by 115 mm. Its 16 GB GDDR6 memory, 22.57 TFLOPS FP32, and 288.0 GB/s bandwidth support high-end gaming and compute. The launch MSRP is 329 USD. Users who need a discrete GPU for modern titles, ray-traced effects, or heavy compute should choose the RX 7600 XT without hesitation.

The Radeon 680M serves a different purpose: it is an integrated processor for mobile or compact systems where a discrete card is impossible. Its 50 W TDP, no external power, and IGP design make it the only choice in that category. The 680M's 768 shading units, 3.379 TFLOPS, and 12 ray accelerators provide adequate performance for older games, light productivity, or media playback. Its 57th percentile versus 60th for the RX 7600 XT shows both sit near the middle of the database, but the absolute score gap of 1813 points (17083 versus 15270) is the real separator. In short, the RX 7600 XT is for users who demand performance; the Radeon 680M is for users who demand integration and efficiency. The data does not support any other conclusion.
