AMD Radeon 540 vs NVIDIA T600 Comparison

The AMD Radeon 540 and NVIDIA T600 represent two very different approaches to entry-level workstation graphics, separated by four years of architecture evolution. Benchmark data shows a decisive performance gap, with the NVIDIA T600 winning both head-to-head tests by substantial margins. The Radeon 540, based on the older GCN 4.0 architecture and a 14nm process, posts an average benchmark score of 7673, placing it in the 41st percentile of all GPUs. The T600, built on Turing architecture and a 12nm process, averages 7035, landing in the 39th percentile. Despite the T600's lower average score, its performance profile is dramatically different, as the head-to-head results reveal.

Head-to-Head Benchmarks

The two available comparative benchmarks paint an unambiguous picture. In Geekbench OpenCL, the NVIDIA T600 scores 27875 against the AMD Radeon 540's 6184. This represents a 77.8% advantage for the T600, meaning the NVIDIA card delivers roughly four and a half times the compute performance in this test. The margin is staggering for a comparison within the same market segment. The Geekbench Vulkan test shows a similar, though slightly narrower, gap: the T600 scores 25580 versus 9162 for the Radeon 540, a 64.2% difference. Even the Radeon's stronger relative showing in Vulkan leaves it far behind, with the T600 still outperforming it by more than 2.7 times.

The T600's dominance extends beyond raw scores. In OpenCL, the Radeon 540's result of 6184 is actually closer to the T600's Vulkan score of 25580 than it is to the T600's OpenCL score of 27875. This suggests the T600's compute advantage is consistent across different API workloads. The Radeon 540's best result, its 9162 Vulkan score, still falls short of the T600's weakest comparative result by a factor of 2.8. Notably, the Radeon 540 has no wins across the head-to-head suite, while the T600 claims both. The delta percentages, -77.8% and -64.2%, indicate the Radeon's deficit relative to the T600, confirming that these are not marginal differences but fundamental performance tier separations.

The Verdict

The data supports a clear conclusion: the NVIDIA T600 is the superior performer in every measurable benchmark category. Its OpenCL score of 27875 places it in a different performance class entirely, and its Vulkan score of 25580 reinforces that position. For any workload relying on compute or graphics acceleration, the T600 delivers results that the Radeon 540 cannot approach. The Radeon 540's 41st percentile ranking versus the T600's 39th percentile might suggest parity, but the head-to-head results override that aggregate statistic. The Radeon's higher average score of 7673 comes from its nearest rivals, which include the GeForce GTX 1660 Ti at 7723 (a 0.6% difference) and the Radeon Pro WX 3100 at 7580 (1.2% ahead). The T600, meanwhile, sits near the GeForce GTX 680M at 7023 (0.2% behind) and the GTX 970 at 7157 (1.7% behind). These rival comparisons show the Radeon 540 competing with mid-range consumer cards from its era, while the T600 aligns with older mobile and desktop parts.

For buyers, the choice is straightforward from benchmark data alone. The T600 offers 4 GB of GDDR6 memory versus the Radeon's 1 GB of GDDR5, a 128-bit bus versus 32-bit, and 160.0 GB/s bandwidth versus 24.00 GB/s. The T600 also has more shading units (640 vs 384), texture mapping units (40 vs 24), and raster operation units (32 vs 16). These hardware differences translate directly into the benchmark results. The T600's pixel rate of 42.72 GPixel/s and texture rate of 53.40 GTexel/s dwarf the Radeon's 18.93 GPixel/s and 28.39 GTexel/s. FP32 compute tells the same story: 1.709 TFLOPS for the T600 versus 908.5 GFLOPS for the Radeon. The T600 is the only rational choice for performance-sensitive applications.

Where Each One Wins

Based strictly on the benchmark data, the NVIDIA T600 wins every scenario that involves compute or graphics acceleration. Its OpenCL advantage of 77.8% makes it the clear pick for general-purpose GPU compute, OpenCL-based rendering, and any workload that leverages the graphics card for non-graphics tasks. The Vulkan advantage of 64.2% extends this to modern graphics APIs, making the T600 suitable for Vulkan-based applications and games. The T600's higher memory capacity (4 GB vs 1 GB) and bandwidth (160.0 GB/s vs 24.00 GB/s) support larger textures and datasets, though these specifications are not directly benchmarked here.

The AMD Radeon 540, despite losing both head-to-head tests, still has a role. Its lower average score of 7673 versus the T600's 7035 is misleading because the Radeon's nearest rivals include stronger parts like the GTX 1660 Ti. The Radeon's 1.2% advantage over the Radeon Pro WX 3100 and 1.5% over the Radeon R7 250 suggests it sits comfortably among entry-level workstation GPUs of its generation. For applications where the T600's performance is unnecessary, the Radeon 540 might suffice, but the data does not show any benchmark where it wins. The T600 wins 2 out of 2 head-to-head tests, making any use-case preference for the Radeon a matter of compatibility or availability rather than performance.

The T600's 4x mini-DisplayPort 1.4a outputs versus the Radeon's 2x DisplayPort 1.4a also gives it an edge in multi-display setups, though this is not benchmarked. The T600 supports DirectX 12 (12_1) and Vulkan 1.4, while the Radeon supports DirectX 12 (12_0) and Vulkan 1.3. These API differences are minor for most workloads but could matter for specific applications. The T600's lower TDP of 40 W versus the Radeon's 50 W is notable, as is its suggested PSU of 200 W versus 250 W. Neither card requires power connectors, and both are single-slot designs.

Architecture Differences

The two GPUs stem from fundamentally different architectures and manufacturing processes. The AMD Radeon 540 uses the Lexa chip based on GCN 4.0 architecture, manufactured on a 14nm process by GlobalFoundries. It belongs to the Polaris (RX 500) generation and contains 2,200 million transistors on a 103 mm² die, yielding a transistor density of 21.4M per mm². The NVIDIA T600 uses the TU117 chip based on Turing architecture, manufactured on a 12nm process by TSMC. It belongs to the Quadro Turing (Tx000) generation and packs 4,700 million transistors on a 200 mm² die, achieving a density of 23.5M per mm².

The memory subsystems are drastically different. The Radeon 540 uses 1024 MB of GDDR5 at 1500 MHz (6 Gbps effective), with a 32-bit bus providing 24.00 GB/s bandwidth. The T600 uses 4 GB of GDDR6 at 1250 MHz (10 Gbps effective), with a 128-bit bus providing 160.0 GB/s bandwidth. This 6.7x bandwidth advantage is a key driver of the T600's performance lead. The Radeon's memory clock is higher in MHz but the effective data rate and bus width favor the T600 overwhelmingly.

Core configurations also differ significantly. The Radeon 540 has 384 shading units, 24 TMUs, and 16 ROPs, while the T600 has 640 shading units, 40 TMUs, and 32 ROPs. The T600's pixel rate of 42.72 GPixel/s and texture rate of 53.40 GTexel/s more than double the Radeon's 18.93 GPixel/s and 28.39 GTexel/s. FP16 performance reveals another architectural difference: the Radeon achieves 908.5 GFLOPS FP16 (1:1 ratio with FP32), while the T600 reaches 3.418 TFLOPS FP16 (2:1 ratio), indicating the Turing architecture's enhanced half-precision throughput.

The T600 also supports a broader feature set. It offers DirectX 12 (12_1) and Vulkan 1.4, while the Radeon supports DirectX 12 (12_0) and Vulkan 1.3. The T600 has four mini-DisplayPort 1.4a outputs versus the Radeon's two DisplayPort 1.4a outputs. The T600's bus interface is PCIe 3.0 x16, whereas the Radeon uses PCIe 3.0 x8, halving the available bandwidth for data transfers. Power consumption favors the T600 at 40 W TDP versus the Radeon's 50 W, and the T600's suggested PSU is 200 W compared to 250 W. Both cards are single-slot with no power connectors, and both are end-of-life products. The Radeon 540 released on 2017-04-19, with the T600 following on 2021-04-11. Their predecessors and successors differ as well: the Radeon follows Arctic Islands and precedes Vega, while the T600 follows Quadro Volta and precedes Workstation Ampere. These architectural and generation gaps explain why the T600, despite its lower aggregate percentile, dominates the head-to-head benchmarks.
