AMD Radeon 680M vs NVIDIA GeForce RTX 5070 SUPER Comparison

The Verdict

The data presents a stark contrast between two very different products. The AMD Radeon 680M is an integrated graphics processor (IGP) designed for mobile systems, while the NVIDIA GeForce RTX 5070 SUPER is a discrete, dual-slot desktop graphics card. The benchmark results indicate a clear performance hierarchy: the RTX 5070 SUPER dominates in raw compute, scoring 2690 in 3DMark Steel Nomad DX12 compared to the 680M's 378, a difference of 85.9%. The RTX 5070 SUPER is the only choice for anyone needing discrete desktop performance, particularly for gaming or content creation workloads. The Radeon 680M, by contrast, serves a different purpose: it provides integrated graphics capability for portable devices where a separate card is not an option. Its recorded data shows a 57th percentile rank among all GPUs, placing it near the NVIDIA GeForce GTX 580 (average score 15283) and RTX 2060 (15290), with a negligible 0.1% difference. The RTX 5070 SUPER sits at the 18th percentile in the database, though this ranking is based on a single benchmark entry and appears anomalous relative to its absolute score. For a system builder, the choice is dictated by form factor and use case: the 680M fits in a thin laptop with no discrete graphics, while the RTX 5070 SUPER requires a full desktop slot, a 275 W power draw, and a 16-pin power connector.

Architecture Differences

The two GPUs come from different architectural generations and process nodes. The AMD Radeon 680M uses the Rembrandt+ chip, built on RDNA 2.0 architecture, which the database lists as part of the Navi II IGP generation. It is fabricated on a 6 nm process at TSMC, containing 13,100 million transistors on a 208 mm² die, yielding a transistor density of 63.0M per mm². The NVIDIA GeForce RTX 5070 SUPER uses the GB205 chip, based on Blackwell 2.0 architecture, part of the GeForce 50 series. It is built on a 5 nm TSMC process with 31,100 million transistors on a 263 mm² die, giving a density of 118.3M per mm². This means the RTX 5070 SUPER packs roughly 2.4 times the transistor count into a die that is only 26% larger by area.

Clock speeds also differ significantly. The 680M has a base clock of 2000 MHz and a boost clock of 2200 MHz. The RTX 5070 SUPER runs a base clock of 2325 MHz and a boost of 2512 MHz. While the clock gap is modest, the architectural differences are vast. The 680M has 768 shading units, 48 texture mapping units (TMUs), and 32 render output units (ROPs), with 12 ray tracing cores. The RTX 5070 SUPER has 6400 shading units, 200 TMUs, 80 ROPs, 50 ray tracing cores, and 200 tensor cores. The FP32 compute throughput tells the story: the 680M delivers 3.379 TFLOPS, while the RTX 5070 SUPER delivers 32.15 TFLOPS, a factor of 9.5. FP16 on the 680M is 6.758 TFLOPS at a 2:1 ratio, while the RTX 5070 SUPER achieves 32.15 TFLOPS at a 1:1 ratio, indicating a different compute architecture that handles FP16 at full rate.

The 680M's memory is entirely system shared, with the bus width, size, and bandwidth all dependent on the host system. The RTX 5070 SUPER has dedicated 18 GB of GDDR7 memory on a 192-bit bus, with 672.0 GB/s of bandwidth and an effective 28 Gbps memory clock. The RTX 5070 SUPER also features a PCIe 5.0 x16 interface, whereas the 680M uses PCIe 4.0 x8. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The 680M's power draw is 50 W with no power connectors, while the RTX 5070 SUPER draws 275 W and requires a single 16-pin connector.

Head-to-Head Benchmarks

The database contains a single head-to-head benchmark between these two GPUs: 3DMark Steel Nomad DX12. In this test, the NVIDIA GeForce RTX 5070 SUPER scores 2690, while the AMD Radeon 680M scores 378. The delta is 85.9% in favor of the RTX 5070 SUPER. This is not a marginal difference; the RTX 5070 SUPER outperforms the 680M by a factor of 7.1. The RTX 5070 SUPER's score of 2690 places it near the NVIDIA Quadro K1100M (2664), GeForce GT 1030 (2662), Intel Arc Pro B50 (2660), and GeForce GT 440 (2645) in the database, though those comparisons are based on average scores and the delta percentages range from 1.0% to 1.7% in favor of the RTX 5070 SUPER.

The 680M's own average benchmark score is 15270, which is much higher than its single Steel Nomad score, because it also has Geekbench OpenCL and Vulkan results. In Geekbench OpenCL, the 680M scores 23468, and in Geekbench Vulkan it scores 21965. The RTX 5070 SUPER has no Geekbench entries in the database. The 680M's average score of 15270 puts it within 0.1% of the NVIDIA GeForce GTX 580 (15283) and RTX 2060 (15290), and 0.5% ahead of the RTX 3050 OEM (15199) and 0.7% ahead of the AMD Radeon RX 7600 (15171).

The RTX 5070 SUPER's percentile rank of 18 versus the 680M's 57 is a reflection of the different benchmark sets available for each. The 680M has three recorded benchmarks, while the RTX 5070 SUPER has only one. The single Steel Nomad score for the RTX 5070 SUPER is high in absolute terms, but the database's percentile calculation places it among lower-ranked cards, which is a data artifact of the limited entries.

Where Each One Wins

The NVIDIA GeForce RTX 5070 SUPER wins the only direct head-to-head benchmark, and it wins by a massive margin. In 3DMark Steel Nomad DX12, its 2690 score is 85.9% above the 680M's 378. This GPU also wins on every architectural specification that matters for compute throughput: 6400 shading units versus 768, 200 TMUs versus 48, 80 ROPs versus 32, 50 RT cores versus 12, and 200 tensor cores versus none. Its FP32 throughput of 32.15 TFLOPS is 9.5 times the 680M's 3.379 TFLOPS. The RTX 5070 SUPER's dedicated 18 GB of GDDR7 with 672.0 GB/s bandwidth vastly exceeds the 680M's system shared memory, which has no fixed bandwidth. The RTX 5070 SUPER also produces a pixel rate of 201.0 GPixel/s versus 70.40 GPixel/s and a texture rate of 502.4 GTexel/s versus 105.6 GTexel/s. This GPU is the clear winner for any desktop workload where maximum performance is required, including gaming, rendering, or compute tasks that benefit from tensor cores and ray tracing hardware.

The AMD Radeon 680M wins in the categories of power efficiency and integration. Its TDP of 50 W is 225 W lower than the RTX 5070 SUPER's 275 W. It requires no external power connectors and occupies no slot width, being an IGP. Its bus interface of PCIe 4.0 x8 is sufficient for an integrated solution. The 680M's Geekbench scores show respectable compute capability for an integrated part: 23468 in OpenCL and 21965 in Vulkan. Its average benchmark score of 15270 places it in the same performance class as the GTX 580 and RTX 2060, which are older discrete GPUs. This indicates that the 680M is a capable integrated solution for light gaming or general productivity on portable devices. The 680M also has a higher percentile rank of 57 versus the RTX 5070 SUPER's 18, though this is based on different benchmark data sets.

For a builder, the choice is clear. The RTX 5070 SUPER is for a desktop system with a dual-slot slot, a 16-pin power connector, and a power supply capable of 275 W. The 680M is for a laptop or compact device where no discrete GPU slot exists. The recorded data shows no scenario where the 680M competes with the RTX 5070 SUPER in raw performance. The RTX 5070 SUPER wins the only benchmark, wins every compute specification, and offers dedicated memory with high bandwidth. The 680M wins on power draw, physical footprint, and integration. The database records the RTX 5070 SUPER as having one win in head-to-head benchmarks and the 680M as having zero.
