AMD Radeon RX 6600 LE vs NVIDIA GeForce RTX 5070 Mobile Comparison

AMD Radeon RX 6600 LE vs NVIDIA GeForce RTX 5070 Mobile

The recorded data presents a direct comparison between two active GPUs from different market segments: the AMD Radeon RX 6600 LE, a desktop card from the Radeon RX 6000 series, and the NVIDIA GeForce RTX 5070 Mobile, a laptop component from the GeForce 50-series. The benchmark results show a clear performance hierarchy, with the NVIDIA GPU dominating the two shared tests, though the architectural and specification differences between the two are substantial, offering distinct profiles for different use cases.

Head-to-Head Benchmarks

The database contains two head-to-head benchmark comparisons, and in both, the NVIDIA GeForce RTX 5070 Mobile emerges as the clear winner. In the Geekbench OpenCL test, the NVIDIA GPU scores 122,238 points, while the AMD Radeon RX 6600 LE scores 69,229 points. This yields a delta of -43.4% for the AMD card, meaning the NVIDIA solution delivers a significant performance advantage of over 76% in raw compute throughput as measured by this test.

The Geekbench Vulkan test shows a similar pattern, though the gap narrows slightly. The RTX 5070 Mobile achieves 116,960 points, while the RX 6600 LE records 72,428 points, resulting in a -38.1% delta. This indicates the AMD card is closer to its rival in Vulkan workloads, but it still trails by a substantial margin. The overall head-to-head tally is 2 wins for NVIDIA and 0 wins for AMD, a definitive result in favor of the GeForce RTX 5070 Mobile.

However, the average benchmark scores tell a more complex story. The RX 6600 LE has an average benchmark score of 70,829, which places it in the 91st percentile among all GPUs. Its nearest rivals include the NVIDIA RTX A3000 Mobile (average score 70,140, delta +1%), the AMD Radeon RX 6650M (average score 71,768, delta -1.3%), and the AMD Radeon Pro WX 8200 (average score 69,870, delta +1.4%). These small deltas indicate the RX 6600 LE sits in a tightly competitive band, trading places with its peers by just a few percentage points.

In contrast, the RTX 5070 Mobile has an average benchmark score of 29,928, which places it in the 75th percentile. This lower percentile reflects the fact that its average is dragged down by a series of Passmark scores that are extremely low, such as 129 for DirectX 10, 192 for DirectX 11, 93 for DirectX 12, and 214 for DirectX 9. These figures are anomalous when compared to its Geekbench results, suggesting the Passmark tests may not be representative of the GPU's full capabilities or may be influenced by the mobile platform's power constraints.

The RTX 5070 Mobile's nearest rivals, based on average score, include the NVIDIA GeForce RTX 3070 Ti (average score 29,945, delta -0.1%), the NVIDIA GeForce RTX 2080 Ti (average score 29,783, delta +0.5%), and the AMD Radeon RX 6800 (average score 30,095, delta -0.6%). This places the RTX 5070 Mobile in a performance class equivalent to previous-generation desktop flagship cards, despite its mobile form factor and lower power envelope.

The Verdict

The data indicates that the NVIDIA GeForce RTX 5070 Mobile is the superior performer in head-to-head testing, winning both shared benchmarks by margins of 43.4% and 38.1%. For tasks that rely on OpenCL or Vulkan compute, such as certain rendering pipelines, physics simulations, or machine learning inference, the RTX 5070 Mobile delivers substantially higher throughput. Its Geekbench OpenCL score of 122,238 is nearly double that of the RX 6600 LE's score of 69,229, a gap that would be noticeable in compute-heavy workloads.

The AMD Radeon RX 6600 LE, however, holds its own in a different sense. Its average benchmark score of 70,829 is far higher than the RTX 5070 Mobile's average of 29,928, and its 91st percentile ranking versus the NVIDIA card's 75th percentile suggests that across a broader set of standardized tests, the AMD card performs more consistently. This discrepancy arises because the RTX 5070 Mobile's Passmark scores (ranging from 93 to 214 in various DirectX tests) are exceptionally low, pulling its average down significantly.

For a user who values raw compute in the specific tests where both GPUs were measured, the RTX 5070 Mobile is the clear choice. For a user who relies on the overall average benchmark score as a proxy for general capability, the RX 6600 LE appears more robust. The data does not support a single winner across all metrics; it supports a split decision based on the workload and the benchmark methodology.

Where Each One Wins

The NVIDIA GeForce RTX 5070 Mobile wins decisively in the two head-to-head benchmarks. In Geekbench OpenCL, it scores 122,238 against 69,229, and in Geekbench Vulkan, it scores 116,960 against 72,428. These are the only direct comparisons available, and they show the NVIDIA GPU delivering leadership in both OpenCL and Vulkan compute environments. The delta percentages, -43.4% and -38.1% respectively, quantify the performance gap, indicating that the RTX 5070 Mobile is between 38% and 43% faster than the RX 6600 LE in these tests.

The AMD Radeon RX 6600 LE wins in the context of the average benchmark score and percentile ranking. Its average score of 70,829 is more than double the RTX 5070 Mobile's 29,928, and its 91st percentile placement is 16 points higher than the NVIDIA card's 75th percentile. This suggests that when considering the entire set of recorded benchmarks, the RX 6600 LE is a more balanced performer, whereas the RTX 5070 Mobile exhibits extreme variance, with strong Geekbench scores but very weak Passmark scores.

The RTX 5070 Mobile also wins on the Passmark GPU Compute test, scoring 8,279, a figure that is not directly comparable to the RX 6600 LE since the AMD card has no Passmark scores recorded. This absence of data for the AMD card in Passmark tests means the overall comparison is incomplete, but the available numbers show the NVIDIA GPU excelling in compute-oriented workloads while the AMD GPU maintains a higher average across the tests it did participate in.

Architecture Differences

The two GPUs are built on fundamentally different architectures from different generations. The AMD Radeon RX 6600 LE uses the Navi 23 chip based on RDNA 2.0 architecture, part of the Navi II (RX 6000) generation. The NVIDIA GeForce RTX 5070 Mobile uses the GB206 chip based on Blackwell 2.0 architecture, part of the GeForce 50 Mobile generation. The process nodes differ as well: AMD uses a 7 nm process from TSMC, while NVIDIA uses a 5 nm process, also from TSMC.

The transistor counts show a significant difference. The AMD chip contains 11,060 million transistors on a die size of 237 mm², resulting in a transistor density of 46.7 million per mm². The NVIDIA chip contains 21,900 million transistors on a smaller die of 181 mm², yielding a much higher density of 121.0 million per mm². This indicates the NVIDIA chip packs nearly twice the transistors into a smaller area, a reflection of the more advanced 5 nm process.

The compute resources also differ sharply. The RX 6600 LE has 1,792 shading units, 112 texture mapping units, and 64 raster operation units. The RTX 5070 Mobile has 4,608 shading units, 144 texture mapping units, and 48 raster operation units. The NVIDIA GPU has far more shading units and TMUs, but fewer ROPs. In terms of ray tracing, the AMD card has 28 ray tracing cores, while the NVIDIA card has 36. The NVIDIA GPU also includes 144 tensor cores, a feature entirely absent from the AMD card, which has no tensor cores listed.

The floating-point performance reflects these differences. The RX 6600 LE delivers 8.942 TFLOPS for FP32 and 17.88 TFLOPS for FP16, with the FP16 rate achieved via a 2:1 ratio. The RTX 5070 Mobile delivers 13.13 TFLOPS for both FP32 and FP16, using a 1:1 ratio, meaning it does not double throughput for half-precision math. The pixel and texture rates also differ: the AMD card achieves 159.7 GPixel/s and 279.4 GTexel/s, while the NVIDIA card achieves 68.40 GPixel/s and 205.2 GTexel/s.

Specification Differences

The memory subsystems are distinct. Both GPUs have 8 GB of memory on a 128-bit bus, but the type and speed differ. The AMD Radeon RX 6600 LE uses GDDR6 memory at 1750 MHz with 14 Gbps effective, providing a bandwidth of 224.0 GB/s. The NVIDIA GeForce RTX 5070 Mobile uses GDDR7 memory at 1500 MHz with 24 Gbps effective, providing a bandwidth of 384.0 GB/s. The NVIDIA card offers 71% more memory bandwidth.

Clock speeds are notably different. The AMD card has a base clock of 1626 MHz, a boost clock of 2495 MHz, and a game clock of 2045 MHz. The NVIDIA card has a base clock of 907 MHz and a boost clock of 1425 MHz, with no game clock listed. Despite the lower clocks, the NVIDIA GPU achieves higher FP32 throughput due to its larger number of shading units.

Power and physical specifications diverge substantially. The AMD Radeon RX 6600 LE has a TDP of 132 W, is a dual-slot card requiring a 1x 8-pin power connector, and has a suggested PSU of 300 W. The NVIDIA GeForce RTX 5070 Mobile has a TDP of 50 W, is listed as an IGP (integrated graphics processor) with no power connectors, and has no suggested PSU. The AMD card measures 190 mm in length, 110 mm in height, and 40 mm in width, while the NVIDIA card has no dimensions recorded.

The bus interfaces also differ. The AMD card uses PCIe 4.0 x8, while the NVIDIA card uses PCIe 5.0 x16. Display outputs are another point of contrast: the AMD card provides 1x HDMI 2.1 and 3x DisplayPort 1.4a, whereas the NVIDIA card lists "Portable Device Dependent" outputs, reflecting its mobile nature. Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, ensuring API feature parity. Release dates are also distinct, with the AMD card released on 2023-12-07 and the NVIDIA card on 2025-04-14.
