GPU Comparison

The data in this comparison is starkly one-sided. The NVIDIA T600, a workstation-oriented Turing GPU from 2021, completely outclasses the AMD Radeon HD 7730M, a mobile GCN 1.0 part from 2012. In the single benchmark where both products have recorded scores, the T600 delivers a 323.6% higher result than the HD 7730M. This is not a close contest; it is a generational and architectural chasm.

Head-to-Head Benchmarks

The only common benchmark data point between the two GPUs is Geekbench OpenCL. Here, the NVIDIA T600 scores 27,875 points, while the AMD Radeon HD 7730M scores 6,581 points. The delta is a massive 323.6% in favor of the T600. This means the T600 is more than four times faster in this compute-oriented workload, a figure that dwarfs any other performance comparison in this dataset.

Looking at the broader benchmark landscape, the T600 has scores in several other tests that the HD 7730M lacks entirely. In Passmark G3D, the T600 scores 6,479, and in Passmark GPU Compute, it scores 2,402. The HD 7730M has no equivalent recorded results for these tests, making direct comparisons impossible. The T600 also posts Geekbench Vulkan score of 25,580, a test the AMD part does not appear in.

The gap in average benchmark scores is equally telling. The T600 has an average benchmark score of 7,035, placing it in the 39th percentile of all GPUs. The HD 7730M's average score is 6,581, which puts it in the 38th percentile. While the percentile ranking is close, the raw score difference is notable: 7,035 versus 6,581. This suggests that while both are positioned in the lower-mid range of the overall GPU landscape, the T600 is still meaningfully ahead in raw performance.

The T600's nearest rivals in the database are the NVIDIA GeForce GTX 680M (avg score 7,023, delta 0.2%), AMD Radeon R5 M240 (avg score 6,975, delta 0.9%), and NVIDIA GeForce GTX 675M (avg score 6,946, delta 1.3%). The HD 7730M, by contrast, sits closest to the Intel UHD Graphics P750 (avg score 6,554, delta 0.4%), AMD Radeon R7 M460 (avg score 6,612, delta -0.5%), and NVIDIA GeForce GTX 670M (avg score 6,513, delta 1.0%). This shows that the T600 is competing against a slightly higher tier of older discrete mobile GPUs, while the HD 7730M is grouped with entry-level integrated and low-end discrete parts.

Where Each One Wins

The NVIDIA T600 wins in every measurable category where both products have data. In the Geekbench OpenCL test, it is the unequivocal victor by a factor of more than four. Its performance profile suggests it is designed for professional workstation tasks that demand sustained compute throughput, such as CAD, 3D modeling, and video encoding. The presence of a Vulkan score (25,580) and multiple DirectX benchmark results (Passmark DX9: 114, DX11: 49, DX10: 32, DX12: 25) indicates a GPU capable of handling modern graphics APIs, albeit with modest results in the older DirectX tests.

The AMD Radeon HD 7730M has no wins in this dataset. Its sole benchmark score is the Geekbench OpenCL result of 6,581, which is less than a quarter of the T600's score. Its performance is characteristic of a low-power mobile GPU from its era, suitable for basic multimedia playback and light 2D workloads. The Passmark G2D score of 756 for the T600 versus no equivalent score for the HD 7730M further underscores the T600's advantage in 2D and desktop composition tasks.

For use cases, the T600 is the clear choice for any workload requiring GPU compute acceleration. The HD 7730M, with its DDR3 memory and limited bandwidth, would be a bottleneck in any modern application. The T600's higher average score and its standing among rivals like the GTX 970 (delta -1.7% from the T600) suggest it can handle lighter gaming and professional applications, while the HD 7730M is relegated to legacy or basic tasks.

Architecture Differences

The two GPUs are built on fundamentally different architectures. The NVIDIA T600 uses the Turing architecture (chip TU117) on a 12 nm TSMC process. It integrates 4,700 million transistors on a 200 mm² die. The AMD Radeon HD 7730M uses the GCN 1.0 architecture (chip Chelsea) on a 28 nm TSMC process, with 1,500 million transistors on a 123 mm² die. This is a significant difference in both process technology and transistor count. The T600 has a transistor density of 23.5 million per mm², whereas the HD 7730M has a density of 12.2 million per mm².

The T600's compute configuration is substantially larger. It has 640 shading units, 40 texture mapping units (TMUs), and 32 ROPs. The HD 7730M has 512 shading units, 32 TMUs, and 16 ROPs. This gives the T600 a 2:1 advantage in ROPs, which directly impacts pixel fill rate. The T600's pixel rate is 42.72 GPixel/s versus the HD 7730M's 10.80 GPixel/s. Texture rate comparison is similarly lopsided: 53.40 GTexel/s for the T600 versus 21.60 GTexel/s for the HD 7730M.

Memory architecture is another major divider. The T600 uses 4 GB of GDDR6 memory on a 128-bit bus, yielding a bandwidth of 160.0 GB/s. The HD 7730M uses 2 GB of DDR3 on a 128-bit bus, but its bandwidth is only 28.80 GB/s. This 5.5x difference in bandwidth is critical for compute and texture-heavy workloads. The T600 also supports higher effective memory speeds at 10 Gbps versus the HD 7730M's 1.8 Gbps.

Feature support also diverges. The T600 supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The HD 7730M supports DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.170. The T600's newer Vulkan support and higher DirectX feature level reflect its more modern design.

Specification Differences

The specification sheet highlights clear generational gaps. The T600 has a base clock of 735 MHz and a boost clock of 1335 MHz; the HD 7730M runs at 575 MHz base and 675 MHz boost. The T600's higher clocks, combined with its superior architecture, drive its performance advantage.

Compute throughput is a major differentiator. The T600 delivers 1.709 TFLOPS of FP32 performance and 3.418 TFLOPS of FP16 (2:1 ratio). The HD 7730M has only 691.2 GFLOPS of FP32 and no listed FP16 capability. This means the T600 has 2.5x the FP32 throughput and a significant advantage in mixed-precision workloads.

Power consumption is one area where the HD 7730M leads. It has a TDP of 25 W, while the T600 has a TDP of 40 W. This makes the HD 7730M more power-efficient in absolute terms, but it comes at a massive cost in performance. The T600 requires a single-slot cooler and a 200 W suggested PSU, whereas the HD 7730M is a mobile part with no discrete power connector specification.

The bus interface differs as well: the T600 uses PCIe 3.0 x16, while the HD 7730M uses PCIe 2.0 x16. This halving of interconnect bandwidth can affect data transfer speeds for large datasets. Display outputs also differ: the T600 has 4x mini-DisplayPort 1.4a, while the HD 7730M is "Portable Device Dependent," meaning its outputs vary by laptop implementation.

Release timing explains many of these differences. The T600 was released in April 2021, while the HD 7730M came out in April 2012, a nine-year gap. The T600's predecessor is Quadro Volta and its successor is Workstation Ampere. The HD 7730M's predecessor is Vancouver and its successor is Solar System. Both are end-of-life products.
