Architecture Differences

The two GPUs come from different architectural generations and foundry processes. The AMD Radeon RX 6450M uses the Navi 24 chip built on RDNA 2.0 architecture, manufactured by TSMC on a 6 nm process. It belongs to the Navi Mobile generation within the RX 6000 series. The NVIDIA GeForce RTX 5070 Ti Mobile uses the GB205 chip built on Blackwell 2.0 architecture, manufactured by TSMC on a 5 nm process, and belongs to the GeForce 50 Mobile generation. The process node difference is 1 nm, which contributes to the NVIDIA chip's higher transistor density.

Transistor counts differ sharply. The RX 6450M contains 5,400 million transistors on a die of 107 mm², giving a density of 50.5 million transistors per mm². The RTX 5070 Ti Mobile contains 31,100 million transistors on a die of 263 mm², giving a density of 118.3 million transistors per mm². The NVIDIA chip has roughly 5.8 times the transistor count of the AMD chip, and its die is about 2.5 times larger. The density advantage for the RTX 5070 Ti Mobile is more than double that of the RX 6450M.

Core configurations follow the same pattern. The RX 6450M has 768 shading units, 48 texture mapping units, 32 render output units, and 12 ray tracing cores. It has no tensor cores. The RTX 5070 Ti Mobile has 5,888 shading units, 184 TMUs, 80 ROPs, 46 ray tracing cores, and 184 tensor cores. The NVIDIA part has 7.7 times the shading units, 3.8 times the TMUs, 2.5 times the ROPs, and 3.8 times the ray tracing cores. The presence of 184 tensor cores on the NVIDIA GPU is a major architectural difference, as the AMD chip has none.

Memory subsystems are also far apart. The RX 6450M uses 4 GB of GDDR6 memory on a 64-bit bus, delivering 128.0 GB/s of bandwidth. The RTX 5070 Ti Mobile uses 12 GB of GDDR7 memory on a 192-bit bus, delivering 672.0 GB/s of bandwidth. The NVIDIA memory capacity is three times larger, the bus width is three times wider, and the bandwidth is 5.25 times higher. The memory clock rates reflect the newer standard: the RX 6450M runs at 2000 MHz with 16 Gbps effective, while the RTX 5070 Ti Mobile runs at 1750 MHz with 28 Gbps effective. The higher effective data rate on the NVIDIA part comes from GDDR7 signaling.

Clock speeds behave differently between the two. The RX 6450M has a base clock of 2000 MHz, a boost clock of 2460 MHz, and a game clock of 2220 MHz. The RTX 5070 Ti Mobile has a base clock of 847 MHz and a boost clock of 1447 MHz. The AMD chip runs at substantially higher clock frequencies, but the NVIDIA chip compensates with far more execution resources. The RX 6450M boost clock is 1013 MHz higher than the RTX 5070 Ti Mobile's boost clock. In terms of raw throughput, the RTX 5070 Ti Mobile delivers 17.04 TFLOPS of FP32 and 17.04 TFLOPS of FP16 at a 1:1 ratio. The RX 6450M delivers 3.779 TFLOPS of FP32 and 7.557 TFLOPS of FP16 at a 2:1 ratio. The NVIDIA part is 4.5 times higher in FP32 throughput. Pixel and texture rates follow the same direction: the RTX 5070 Ti Mobile reaches 115.8 GPixel/s and 266.2 GTexel/s, while the RX 6450M reaches 78.72 GPixel/s and 118.1 GTexel/s.

Power and interface details also differ. The RX 6450M carries a TDP of 50 W, while the RTX 5070 Ti Mobile carries a TDP of 60 W. Both are integrated graphics packages with no power connectors. The RX 6450M uses PCIe 4.0 x4, while the RTX 5070 Ti Mobile uses PCIe 5.0 x16. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Both are classified as portable-device dependent for display outputs. The RX 6450M was released on 2023-01-03, while the RTX 5070 Ti Mobile was released on 2025-02-28. The RX 6450M lists Polaris Mobile as its predecessor; the RTX 5070 Ti Mobile lists GeForce 40 Mobile as its predecessor.

Where Each One Wins

The RTX 5070 Ti Mobile wins in every measured category where data exists. Its average benchmark score of 35,435 places it at the 80th percentile, compared to the RX 6450M's 50th percentile with an average score of 0. The RTX 5070 Ti Mobile has recorded results across OpenCL, Vulkan, and multiple DirectX and compute tests; the RX 6450M has none. In compute-heavy workloads, the RTX 5070 Ti Mobile's Geekbench OpenCL score of 143,870 and Vulkan score of 139,213 indicate strong general-purpose throughput. Its Passmark GPU compute score of 10,101 provides additional evidence of compute capability. The RX 6450M cannot be compared on these tests because no scores exist in the database.

The RTX 5070 Ti Mobile also wins on memory capacity and bandwidth. With 12 GB of GDDR7 memory and 672.0 GB/s of bandwidth, it can hold larger working sets and move data faster than the RX 6450M's 4 GB GDDR6 configuration at 128.0 GB/s. The 64-bit memory bus on the RX 6450M limits its bandwidth ceiling regardless of clock speed. The RTX 5070 Ti Mobile's PCIe 5.0 x16 interface provides a wider data path to the host system than the RX 6450M's PCIe 4.0 x4 connection. For workloads that stream data from system memory, the bus width difference is a structural advantage.

The RX 6450M holds advantages in specific non-performance areas. Its TDP of 50 W is 10 W lower than the RTX 5070 Ti Mobile's 60 W. Its clock speeds are higher: a 2000 MHz base and 2460 MHz boost versus 847 MHz base and 1447 MHz boost. For tasks that are latency-sensitive and clock-bound, the higher-frequency AMD part may respond differently, though no benchmark data confirms this. Its smaller die of 107 mm² and lower transistor count of 5,400 million suggest a lower manufacturing cost profile, but the database provides no pricing data. Its release date of 2023-01-03 makes it earlier to market by over two years, which may matter for platform availability timelines.

The Verdict

The recorded data makes the performance hierarchy unambiguous. The RTX 5070 Ti Mobile holds the 80th percentile position among all GPUs, while the RX 6450M sits at the 50th percentile with no recorded benchmark scores. The RTX 5070 Ti Mobile's 35,435 average benchmark score places it within 2.4% of the NVIDIA T1000 and within 0.2% of the NVIDIA Quadro GV100, meaning it trades blows with established workstation-class hardware. The RX 6450M has no comparable data points in the database.

The selection between these two parts depends on workload requirements. For compute-heavy applications, measured OpenCL, Vulkan, and Passmark compute results all favor the RTX 5070 Ti Mobile. Its 12 GB memory capacity and 672.0 GB/s bandwidth support larger datasets and higher throughput than the RX 6450M's 4 GB and 128.0 GB/s. The NVIDIA chip's 5,888 shading units, 184 TMUs, and 46 ray tracing cores provide a structural foundation for high-end rendering and ray-traced workloads. The 184 tensor cores add a capability the AMD part lacks entirely.

The RX 6450M is the lower-power option at 50 W versus 60 W. It runs at higher clock frequencies, with a 2460 MHz boost versus 1447 MHz. Its smaller footprint and lower transistor count suggest a more modest implementation. The database assigns it no measured wins, and its percentiles confirm a wide gap. For users who prioritize measured compute and graphics performance, the RTX 5070 Ti Mobile is the only choice supported by data. For users who need the lowest power envelope and highest clock rates in a physically smaller design, the RX 6450M offers those attributes, but no benchmark results verify its real-world behavior.
