AMD Radeon HD 7730M vs NVIDIA GeForce RTX 5070 Ti SUPER Comparison

The AMD Radeon HD 7730M and the NVIDIA GeForce RTX 5070 Ti SUPER represent two extremes of the GPU spectrum, separated by over a decade of architectural evolution. The data shows a mobile chip from 2012 built on a 28 nm process, while the other is a 2025 desktop behemoth on a 5 nm node. Their benchmark scores, however, tell a more nuanced story than a simple generational gap, as each is measured by different workloads and sits in different performance percentiles.

The Verdict

The choice between these two GPUs is not a matter of preference but of platform and purpose. The AMD Radeon HD 7730M is a 25 W mobile part designed for laptops, with a benchmark score of 6581 in Geekbench OpenCL and a 38th percentile ranking among all GPUs. It is end-of-life and targets legacy systems. The NVIDIA GeForce RTX 5070 Ti SUPER, conversely, is an active, dual-slot desktop card with a 350 W TDP, a 16 GB GDDR7 frame buffer, and a 3DMark Steel Nomad DX12 score of 6269.5, placing it in the 36th percentile. For any modern gaming, rendering, or compute task, the RTX 5070 Ti SUPER is the only viable option. The HD 7730M should only be considered for those maintaining or repairing vintage laptops where its 2 GB DDR3 memory and 28.80 GB/s bandwidth are sufficient for basic 2D workloads or very old 3D titles. The data strongly indicates that the RTX 5070 Ti SUPER is the superior product by every architectural and performance metric that matters today.

Architecture Differences

The architectural gap between these two GPUs is immense. The AMD Radeon HD 7730M is built on GCN 1.0 architecture, using the "Chelsea" chip manufactured on a 28 nm process at TSMC. It packs 1,500 million transistors onto a 123 mm² die, resulting in a transistor density of 12.2M per mm². Its memory subsystem is a 2 GB DDR3 frame buffer on a 128-bit bus, yielding 28.80 GB/s of bandwidth. The chip contains 512 shading units, 32 texture mapping units (TMUs), and 16 raster output units (ROPs). Its compute capabilities are modest, with an FP32 throughput of 691.2 GFLOPS, a pixel rate of 10.80 GPixel/s, and a texture rate of 21.60 GTexel/s. It supports DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.170, and connects via PCIe 2.0 x16.

The NVIDIA GeForce RTX 5070 Ti SUPER is built on the Blackwell 2.0 architecture, using the GB203 chip on a 5 nm process, also from TSMC. It contains 45,600 million transistors on a 378 mm² die, achieving a much higher density of 120.6M per mm². The memory is a 16 GB GDDR7 frame buffer on a 256-bit bus, providing a massive 896.0 GB/s of bandwidth. The GPU features 8,960 shading units, 280 TMUs, and 96 ROPs, along with 70 dedicated ray tracing cores and 280 tensor cores. Its FP32 performance is a staggering 43.94 TFLOPS, with FP16 performance matching at 43.94 TFLOPS (1:1). Pixel rate is 235.4 GPixel/s and texture rate is 686.6 GTexel/s. It supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, and uses PCIe 5.0 x16. The RTX 5070 Ti SUPER also has a 304 mm length, 137 mm height, and 48 mm width, making it a physically large card.

Where Each One Wins

The AMD Radeon HD 7730M wins only in the context of its original purpose: low-power mobile computing. Its 25 W TDP is a fraction of the RTX 5070 Ti SUPER's 350 W, making it suitable for thin-and-light laptops of its era. In terms of benchmark performance, it is essentially tied with its nearest rivals, including the Intel UHD Graphics P750 (0.4% faster) and the AMD Radeon R7 M460 (0.5% slower). It has no ray tracing or tensor core capabilities, so it cannot compete in any modern graphical workload. Its only benchmark score is 6581 in Geekbench OpenCL, which is a compute test that does not reflect gaming performance.

The NVIDIA GeForce RTX 5070 Ti SUPER wins in every modern category. Its 3DMark Steel Nomad DX12 score of 6269.5, while placing it in the 36th percentile, shows it is competitive with its direct rivals. It is exactly tied (0% delta) with the NVIDIA GeForce RTX 4070 Ti SUPER AD102, and it is 0.8% faster than the AMD FirePro W600. The presence of 70 RT cores and 280 tensor cores means it is designed for hardware-accelerated ray tracing and AI workloads, something the AMD chip cannot do. Its 16 GB GDDR7 memory and 896.0 GB/s bandwidth provide ample headroom for high-resolution textures and data-intensive tasks. The RTX 5070 Ti SUPER also supports the latest API standards, including DirectX 12 Ultimate and Vulkan 1.4, ensuring compatibility with current and future software.

Head-to-Head Benchmarks

Direct head-to-head benchmark comparisons are not available in the data, as the two GPUs are tested with different workloads. The AMD Radeon HD 7730M has a single benchmark result: 6581 in Geekbench OpenCL. The NVIDIA GeForce RTX 5070 Ti SUPER has a single result: 6269.5 in 3DMark Steel Nomad DX12. These tests are not interchangeable and measure different aspects of performance (compute vs. gaming graphics).

However, the data allows for a comparison of their standing relative to their peers. The HD 7730M's score of 6581 is 1.4% higher than that of the NVIDIA GeForce GT 555M (6493), showing it was a competitive mobile part in its day. Conversely, the RTX 5070 Ti SUPER's score of 6269.5 is 0.8% higher than the AMD FirePro W600's 6223, demonstrating its edge over a professional workstation card from a different generation.

The most telling comparison comes from the percentile ranks. The HD 7730M sits in the 38th percentile of all GPUs, while the RTX 5070 Ti SUPER sits in the 36th percentile. While these are close, they are not directly comparable due to the different benchmark suites. The architectural specifications paint the clearest picture. The RTX 5070 Ti SUPER has 8,960 shading units versus 512, 280 TMUs versus 32, and 96 ROPs versus 16. Its memory bandwidth is over 31 times higher, and its FP32 compute is over 63 times higher. The RTX 5070 Ti SUPER also adds hardware features like ray tracing and tensor cores, which are entirely absent from the HD 7730M. In every measurable specification, the NVIDIA card is a superior product. The only metric where the AMD chip wins is power consumption, drawing 25 W versus the NVIDIA card's 350 W.
