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

Head-to-Head Benchmarks

The recorded data shows a decisive win for the NVIDIA GeForce RTX 5070 Ti Mobile in both available head-to-head tests. In Geekbench OpenCL, the NVIDIA part scores 143,870 against the AMD Radeon RX 6600 LE’s 69,229, a delta of -51.9% from AMD’s perspective. That means the NVIDIA GPU delivers more than double the OpenCL compute throughput. The Geekbench Vulkan test tells a similar story: NVIDIA scores 139,213 versus AMD’s 72,428, a -48% gap. These are large, consistent margins across both APIs, indicating a fundamental performance advantage rather than an API-specific quirk.

The AMD card’s average benchmark score across its two recorded tests is 70,829, while the NVIDIA card’s average across its nine recorded tests is 35,435. That average is heavily skewed by the low Passmark scores, which are not comparable to Geekbench results. Looking at the head-to-head data alone, the NVIDIA GPU wins both tests. The AMD GPU’s percentile ranking against all GPUs is 91, which is higher than NVIDIA’s 80, but that percentile includes a broader set of benchmarks and reflects the AMD card’s consistency across its limited test set. The NVIDIA card’s Passmark scores show a different profile: G3D at 24,004, GPU compute at 10,101, and DirectX 11 at 237, which are far below its Geekbench numbers, suggesting the two benchmark families measure different workloads.

The delta percentages in the head-to-head section are unambiguous. For OpenCL, AMD trails by 51.9%. For Vulkan, AMD trails by 48%. No single test favors the AMD card. The nearest rivals for the AMD card include the NVIDIA RTX A3000 Mobile with an average score of 70,140 and a delta of 1%, meaning the A3000 is essentially tied with the RX 6600 LE. The AMD Radeon RX 6650M scores 71,768, putting it 1.3% ahead of the RX 6600 LE. For the NVIDIA card, the nearest rival is the NVIDIA Quadro GV100 with an average score of 35,520 and a delta of -0.2%, meaning the RTX 5070 Ti Mobile is essentially tied with that workstation GPU in average score. The AMD Radeon Pro Duo scores 35,860, which is 1.2% ahead of the RTX 5070 Ti Mobile. These rival comparisons show that both cards sit in different performance tiers relative to their peers.

Architecture Differences

The two GPUs come from completely different architectural generations. The AMD Radeon RX 6600 LE uses the Navi 23 chip based on RDNA 2.0, built on a 7 nm process at TSMC. The NVIDIA GeForce RTX 5070 Ti Mobile uses the GB205 chip based on Blackwell 2.0, built on a 5 nm process at TSMC. The transistor counts differ sharply: AMD packs 11,060 million transistors into a 237 mm² die, giving a transistor density of 46.7 million per mm². NVIDIA packs 31,100 million transistors into a 263 mm² die, yielding a density of 118.3 million per mm². That is more than double the density, which explains how NVIDIA fits so many more compute units into a similar physical footprint.

The core configurations are not comparable in a simple way. The AMD GPU has 1,792 shading units, 112 texture mapping units, 64 ROPs, and 28 ray tracing cores. The NVIDIA GPU has 5,888 shading units, 184 TMUs, 80 ROPs, and 46 ray tracing cores. NVIDIA also includes 184 tensor cores, which AMD does not list. Clock speeds reverse the trend: AMD runs at a base of 1626 MHz and a boost of 2495 MHz, with a game clock of 2045 MHz. NVIDIA runs at a base of 847 MHz and a boost of 1447 MHz. Despite the lower clocks, NVIDIA’s much larger shader count produces significantly higher raw compute: 17.04 TFLOPS FP32 versus AMD’s 8.942 TFLOPS. NVIDIA achieves this at a much lower TDP of 60 W, while AMD lists 132 W. That is a remarkable efficiency difference, though the NVIDIA part is an integrated GPU (IGP) with no power connectors, while AMD is a dual-slot card requiring a single 8-pin connector and a 300 W power supply.

Memory subsystems diverge completely. AMD uses 8 GB of GDDR6 on a 128-bit bus, delivering 224.0 GB/s of bandwidth. NVIDIA uses 12 GB of GDDR7 on a 192-bit bus, delivering 672.0 GB/s, exactly three times the bandwidth. Memory clocks are listed as 1750 MHz for both, but effective rates differ: AMD at 14 Gbps and NVIDIA at 28 Gbps. The bus interface also differs: AMD uses PCIe 4.0 x8, while NVIDIA uses PCIe 5.0 x16. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Display outputs differ: AMD provides 1x HDMI 2.1 and 3x DisplayPort 1.4a, while NVIDIA’s outputs are listed as portable device dependent, reflecting its mobile IGP nature.

Where Each One Wins

Based on the head-to-head data, the NVIDIA GeForce RTX 5070 Ti Mobile wins every recorded benchmark comparison. The OpenCL test shows a 51.9% lead, and the Vulkan test shows a 48% lead. The NVIDIA card also has a much larger memory pool at 12 GB versus 8 GB, triple the memory bandwidth at 672.0 GB/s versus 224.0 GB/s, and significantly higher FP32 compute at 17.04 TFLOPS versus 8.942 TFLOPS. The NVIDIA card achieves this while consuming less than half the power: 60 W versus 132 W. For any workload that stresses compute throughput, memory bandwidth, or ray tracing (with 46 RT cores versus 28), the NVIDIA part is the clear choice.

The AMD Radeon RX 6600 LE does have some advantages in the recorded specifications, though not in the benchmark scores. It has a higher boost clock at 2495 MHz versus 1447 MHz, which can benefit lightly threaded or latency-sensitive workloads that do not scale with shader count. It also has a higher pixel rate at 159.7 GPixel/s versus 115.8 GPixel/s, and a higher texture rate at 279.4 GTexel/s versus 266.2 GTexel/s. These rasterization-focused metrics suggest the AMD card can fill pixels faster in certain rendering scenarios, even though it loses in raw compute. The AMD card also has a higher percentile ranking against all GPUs at 91 versus 80, which indicates that its average benchmark score places it higher in the overall distribution than the NVIDIA card’s average score does. However, that percentile is based on a limited test set for AMD (two Geekbench tests) versus a broader set for NVIDIA (nine tests including Passmark).

The AMD card’s nearest rivals include the NVIDIA RTX A3000 Mobile with a delta of 1%, meaning the two are statistically tied. The NVIDIA card’s nearest rivals include the NVIDIA Quadro GV100 with a delta of -0.2%, also a statistical tie. This suggests that in average benchmark terms, the RX 6600 LE competes with mobile workstation GPUs, while the RTX 5070 Ti Mobile competes with high-end workstation GPUs from a previous generation. The use-case split is clear: NVIDIA dominates in compute and memory bandwidth, while AMD has specific advantages in pixel fill and clock speed that may matter in particular rendering pipelines.

The Verdict

The benchmark data points to a single conclusion: the NVIDIA GeForce RTX 5070 Ti Mobile is the faster GPU in every head-to-head comparison recorded. It leads by 51.9% in OpenCL and 48% in Vulkan. Its architecture advantages are overwhelming: 5,888 shading units versus 1,792, 184 tensor cores versus none, 46 RT cores versus 28, and 12 GB of GDDR7 versus 8 GB of GDDR6. The NVIDIA card also delivers 17.04 TFLOPS of FP32 compute against AMD’s 8.942 TFLOPS, while consuming 60 W against AMD’s 132 W. For any user prioritizing compute performance, memory bandwidth, or power efficiency, the NVIDIA part is the only rational choice based on the recorded data.

The AMD Radeon RX 6600 LE does have a higher percentile ranking at 91 versus 80, and its average benchmark score of 70,829 is higher than NVIDIA’s 35,435. But that average is misleading because it does not include the same test set. The AMD card also has higher pixel and texture rates, and a higher boost clock. These metrics may matter in specific rasterization workloads, but they do not translate into wins in the recorded Geekbench tests. The AMD card’s nearest rivals are all within 1.4% in average score, placing it in a competitive mid-range tier. The NVIDIA card’s nearest rivals are also within 2.4%, but those rivals are high-end workstation parts like the Quadro GV100. The data favors NVIDIA for raw performance, and AMD for specific rasterization characteristics that do not show up in the head-to-head wins.
