AMD Radeon 680M vs NVIDIA GeForce RTX 5070 Mobile Comparison

Head-to-Head Benchmarks

The recorded head-to-head data contains two comparison points, and the NVIDIA GeForce RTX 5070 Mobile wins both decisively. In Geekbench OpenCL, the RTX 5070 Mobile scores 122,238 against the AMD Radeon 680M's 23,468. That is a delta of -80.8% for the AMD part, meaning the NVIDIA GPU delivers roughly five times the compute throughput in this workload. The Geekbench Vulkan result tells a similar story: the RTX 5070 Mobile posts 116,960 while the Radeon 680M manages 21,965, a delta of -81.2%. These are not narrow margins; they represent a fundamental performance tier gap.

The average benchmark score reinforces the separation. The Radeon 680M carries an average of 15,270 across its recorded tests, while the RTX 5070 Mobile averages 29,928. That places the NVIDIA part at roughly double the aggregate score of the AMD IGP. In terms of percentile ranking against all GPUs in the database, the Radeon 680M sits at the 57th percentile, whereas the RTX 5070 Mobile reaches the 75th percentile. The nearest rivals for each part further contextualize the gap: the Radeon 680M sits within 0.7% of the AMD Radeon RX 7600 (15,171) and within 0.1% of the NVIDIA GeForce RTX 2060 (15,290), while the RTX 5070 Mobile trades blows with the NVIDIA GeForce RTX 3070 Ti (29,945, -0.1%) and the AMD Radeon RX 6800 (30,095, -0.6%). The RTX 5070 Mobile is effectively competing with desktop-class discrete GPUs from the previous generation, while the Radeon 680M is an integrated solution hovering near older mid-range discrete cards.

The 3DMark Steel Nomad DX12 result for the Radeon 680M is 378, a score that reflects its integrated positioning. No comparable 3DMark run is recorded for the RTX 5070 Mobile, so direct comparison on that specific test is not possible, but the PassMark suite for the NVIDIA part shows a G3D score of 20,355, which is far above the AMD part's entire benchmark profile. The RTX 5070 Mobile also records PassMark GPU compute at 8,279, DirectX 11 at 192, DirectX 9 at 214, DirectX 10 at 129, DirectX 12 at 93, and G2D at 896. None of these have direct equivalents in the Radeon 680M's limited test set, but the scale of the compute numbers alone indicates a large performance chasm.

Architecture Differences

The two GPUs come from entirely different design philosophies. The AMD Radeon 680M uses the RDNA 2.0 architecture on a 6 nm TSMC process, with the chip designated as Rembrandt+. It is an integrated graphics processor (IGP) belonging to the Navi II IGP generation for Rembrandt Mobile. The NVIDIA GeForce RTX 5070 Mobile uses the Blackwell 2.0 architecture on a 5 nm TSMC process, with the chip designated as GB206, part of the GeForce 50 Mobile generation. The process node difference is small (6 nm vs. 5 nm), but the transistor counts diverge sharply: the Radeon 680M packs 13,100 million transistors on a 208 mm² die, while the RTX 5070 Mobile contains 21,900 million transistors on a smaller 181 mm² die. That yields a transistor density of 63.0M per mm² for the AMD part versus 121.0M per mm² for the NVIDIA part, indicating a much denser implementation in the latter.

Core resources differ by a wide margin. The Radeon 680M has 768 shading units, 48 texture mapping units, and 32 ROPs. The RTX 5070 Mobile has 4,608 shading units, 144 TMUs, and 48 ROPs. That is six times the shading units and three times the TMUs, though the ROP count is only 1.5 times higher. Ray tracing cores also differ: 12 for the AMD IGP versus 36 for the NVIDIA part. The RTX 5070 Mobile adds 144 tensor cores, a feature entirely absent from the Radeon 680M's specification sheet. The FP32 throughput tells the story of raw compute: 3.379 TFLOPS for the Radeon 680M versus 13.13 TFLOPS for the RTX 5070 Mobile. FP16 performance is 6.758 TFLOPS (2:1 ratio) for AMD and 13.13 TFLOPS (1:1 ratio) for NVIDIA, meaning the NVIDIA part does not halve its rate for FP16.

Memory architecture is another fundamental split. The Radeon 680M uses system shared memory, with size, type, bus width, and bandwidth all listed as "System Shared" or "System Dependent." The RTX 5070 Mobile has dedicated 8 GB of GDDR7 on a 128-bit bus, delivering 384.0 GB/s of bandwidth. Clock behavior also differs: the Radeon 680M has a base clock of 2000 MHz and a boost of 2200 MHz, while the RTX 5070 Mobile runs a base of 907 MHz and a boost of 1425 MHz. Despite the lower clocks, the NVIDIA part achieves far higher throughput due to its massive core count and dedicated memory. The pixel rate is nearly identical (70.40 GPixel/s for AMD, 68.40 GPixel/s for NVIDIA), but the texture rate is roughly double on the RTX 5070 Mobile (205.2 GTexel/s versus 105.6 GTexel/s). Both parts share the same API support: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The bus interface differs as well. The Radeon 680M uses PCIe 4.0 x8, while the RTX 5070 Mobile uses PCIe 5.0 x16. Both are listed with a 50 W TDP and no power connectors, and both are classified as IGP with portable-device-dependent display outputs. The Radeon 680M has no tensor cores, while the RTX 5070 Mobile has 144, which matters for any workload using AI acceleration. The production status for both is Active.

Where Each One Wins

The RTX 5070 Mobile wins every recorded head-to-head benchmark, so the use-case split is lopsided but still informative. The Geekbench OpenCL result of 122,238 versus 23,468 makes the NVIDIA part the clear choice for compute-heavy workloads that rely on OpenCL, such as general-purpose GPU computing, physics simulations, or data-parallel tasks. The Geekbench Vulkan result of 116,960 versus 21,965 similarly favors the RTX 5070 Mobile for Vulkan-based gaming or rendering applications. The RTX 5070 Mobile also has dedicated 8 GB of GDDR7 memory with 384.0 GB/s bandwidth, whereas the Radeon 680M must share system memory with the CPU, which can bottleneck memory-intensive operations.

For the Radeon 680M, the wins are not in raw performance but in specific attributes. It has a higher base and boost clock (2000 MHz and 2200 MHz versus 907 MHz and 1425 MHz), which can help in latency-sensitive or lightly threaded scenarios where the GPU is not the bottleneck. Its pixel rate of 70.40 GPixel/s is slightly above the RTX 5070 Mobile's 68.40 GPixel/s, so in pure fill-rate-limited situations, the AMD part may hold its own. The Radeon 680M also uses PCIe 4.0 x8, which is adequate for an IGP and does not require a separate power connector. However, the RTX 5070 Mobile also uses no power connector, so that is not a differentiator.

In practical terms, the RTX 5070 Mobile wins for any discrete GPU workload: modern gaming at high settings, ray-traced content, machine learning inference with tensor cores, and high-bandwidth tasks. The Radeon 680M is an integrated solution that wins only in scenarios where the system has no discrete GPU and the user needs a basic graphics output with some compute capability. The PassMark DirectX scores for the RTX 5070 Mobile (DirectX 9 at 214, DirectX 11 at 192, DirectX 12 at 93) show that even legacy API performance is strong, while the Radeon 680M has no recorded PassMark data to compare.

The Verdict

The data is unambiguous. The NVIDIA GeForce RTX 5070 Mobile is in a different performance class than the AMD Radeon 680M. Its average benchmark score of 29,928 is roughly double the Radeon 680M's 15,270, and its percentile rank of 75 versus 57 places it well above most GPUs in the database. The RTX 5070 Mobile's nearest rivals are the RTX 3070 Ti (29,945, -0.1%), the RTX 2080 Ti (29,783, 0.5%), the RX 6800 (30,095, -0.6%), and the RX 6700 (30,433, -1.7%), all of which are desktop discrete GPUs. The Radeon 680M's nearest rivals are the GTX 580 (15,283, -0.1%), RTX 2060 (15,290, -0.1%), RTX 3050 OEM (15,199, 0.5%), and RX 7600 (15,171, 0.7%), which are older or lower-tier cards.

For users who need a GPU for gaming, rendering, or compute, the RTX 5070 Mobile is the only sensible choice from this comparison. Its 13.13 TFLOPS FP32, 36 ray tracing cores, 144 tensor cores, and dedicated 8 GB GDDR7 memory provide capabilities the Radeon 680M cannot match. The Radeon 680M is suitable for basic display output and light compute in a system without a discrete GPU, but its 3.379 TFLOPS FP32 and system-shared memory limit it to low-end tasks. The RTX 5070 Mobile also has a higher transistor density (121.0M per mm²) and a newer architecture (Blackwell 2.0 versus RDNA 2.0), which contributes to its efficiency despite identical 50 W TDP ratings. The verdict from the recorded data is that the RTX 5070 Mobile is the superior part by every measurable performance metric, and the Radeon 680M should only be considered where the integrated form factor and lower absolute transistor count are the primary constraints.
