AMD Radeon RX 6450M vs NVIDIA GeForce RTX 5070 SUPER Comparison

Head-to-Head Benchmarks

The recorded database contains a single 3DMark Steel Nomad DX12 benchmark result for the NVIDIA GeForce RTX 5070 SUPER, scoring 2690 points. This places the card at the 18th percentile among all GPUs in the database. The AMD Radeon RX 6450M has no benchmark entries, so direct numerical comparison between the two is limited to the specification sheet. The RTX 5070 SUPER's nearest rivals in the database are the NVIDIA Quadro K1100M at 2664 points, the NVIDIA GeForce GT 1030 at 2662 points, the Intel Arc Pro B50 at 2660 points, and the NVIDIA GeForce GT 440 at 2645 points. The RTX 5070 SUPER leads these by margins of 1.0%, 1.1%, 1.1%, and 1.7% respectively, indicating that its 2690 score is a modest improvement over a cluster of older or lower-tier parts.

The RX 6450M's absence from the benchmark table means it cannot be situated relative to the RTX 5070 SUPER through measured performance data. What the database does show is a massive gap in raw compute specifications. The RTX 5070 SUPER delivers 32.15 TFLOPS of FP32 performance versus 3.779 TFLOPS for the RX 6450M, a factor of roughly 8.5x. Pixel throughput stands at 201.0 GPixel/s versus 78.72 GPixel/s, and texture rate at 502.4 GTexel/s versus 118.1 GTexel/s. These are not close figures; they describe two entirely different performance classes.

The RTX 5070 SUPER also holds the 50th percentile ranking among all GPUs, while the RX 6450M sits at the 50th percentile as well, though this parity is misleading given the absence of benchmark data for the AMD part. The RTX 5070 SUPER's single benchmark score of 2690 is its average and only recorded result, so the percentile reflects that specific measurement. The RX 6450M's percentile comes from its specification-derived standing, not from any executed test.

FAQ

A: The RTX 5070 SUPER is a dual-slot card measuring 245 mm in length, 115 mm in height, and 40 mm in width. The RX 6450M is an IGP (integrated graphics processor) with no listed dimensions, length, height, or width, and no power connectors.

Architecture Differences

The RX 6450M uses the Navi 24 chip built on RDNA 2.0 architecture, part of the Navi Mobile (RX 6000M) generation. It is manufactured on a 6 nm process at TSMC, with 5,400 million transistors on a 107 mm² die. The RTX 5070 SUPER uses the GB205 chip on Blackwell 2.0 architecture, part of the GeForce 50 generation. It is built on a 5 nm process at TSMC, with 31,100 million transistors on a 263 mm² die. The transistor density difference is stark: 50.5M per mm² for the AMD part versus 118.3M per mm² for the NVIDIA part, reflecting the newer process and more complex design.

The RX 6450M has 768 shading units, 48 texture mapping units, 32 raster output units, and 12 ray tracing cores. It has no tensor cores. The RTX 5070 SUPER has 6,400 shading units, 200 TMUs, 80 ROPs, 50 RT cores, and 200 tensor cores. The tensor core count is a functional difference: the NVIDIA architecture includes dedicated hardware for AI workloads, while the AMD architecture does not list any equivalent.

Memory architecture differs fundamentally. The RX 6450M uses 4 GB of GDDR6 on a 64-bit bus, with memory clocked at 2000 MHz (16 Gbps effective). The RTX 5070 SUPER uses 18 GB of GDDR7 on a 192-bit bus, with memory at 1750 MHz (28 Gbps effective). The GDDR7 type and wider bus give the NVIDIA card a 672.0 GB/s bandwidth, compared to 128.0 GB/s for the AMD card. FP16 compute also differs: the RX 6450M delivers 7.557 TFLOPS at a 2:1 ratio to FP32, while the RTX 5070 SUPER delivers 32.15 TFLOPS at a 1:1 ratio, meaning it does not halve throughput for half-precision work.

The RX 6450M uses a PCIe 4.0 x4 interface, while the RTX 5070 SUPER uses PCIe 5.0 x16, offering 16 times the lane count and a newer standard. Display outputs differ as well: the RX 6450M is listed as "Portable Device Dependent," indicating its outputs vary by laptop implementation, while the RTX 5070 SUPER has fixed outputs of 1x HDMI 2.1b and 3x DisplayPort 2.1b.

Where Each One Wins

The RTX 5070 SUPER wins on every measurable compute specification in the database. Its FP32 throughput of 32.15 TFLOPS is roughly 8.5x the RX 6450M's 3.779 TFLOPS. The 18 GB of GDDR7 memory with 672.0 GB/s bandwidth dwarfs the 4 GB GDDR6 with 128.0 GB/s, making the NVIDIA card suited for large dataset workloads, high-resolution textures, and memory-intensive applications. The 200 tensor cores provide AI acceleration capabilities that the RX 6450M cannot offer at all, and the 50 RT cores versus 12 gives the RTX 5070 SUPER a substantial advantage in ray-traced rendering workloads.

The RX 6450M wins on power efficiency and physical footprint. Its 50 W TDP is less than one-fifth of the RTX 5070 SUPER's 275 W, and its IGP form factor with no power connectors means it can be integrated into thin, portable devices without discrete power delivery. The 6 nm process and smaller die (107 mm² versus 263 mm²) contribute to this lower power draw, though the RTX 5070 SUPER's higher transistor density (118.3M / mm² versus 50.5M / mm²) indicates more efficient use of silicon area per transistor.

The release dates differ by nearly three years, with the RX 6450M launching on 2023-01-03 and the RTX 5070 SUPER on 2025-12-31. The RTX 5070 SUPER's single benchmark score of 2690 places it in the 18th percentile, while the RX 6450M's unmeasured standing is at the 50th percentile. The database shows no benchmark overlap, so head-to-head wins are inferred from specifications rather than direct measurements.

For use cases, the RTX 5070 SUPER is the clear choice for desktop gaming, rendering, AI inference, and any workload requiring high memory capacity or bandwidth. The RX 6450M serves a different purpose: mobile integration where power draw, heat, and physical space are constrained. The dual-slot, 245 mm long RTX 5070 SUPER with a 16-pin connector cannot fit in the same chassis class as the IGP RX 6450M. Each wins in its intended environment, with the NVIDIA card dominating raw performance and the AMD card dominating efficiency and portability.
