AMD Radeon RX 7600 vs NVIDIA T400 4 GB Comparison

Head-to-Head Benchmarks

The recorded data places these two GPUs at opposite ends of the performance spectrum. In the two shared benchmark tests, the AMD Radeon RX 7600 wins both outright, and the margins are substantial. In Geekbench OpenCL, the RX 7600 scores 88,051 against the NVIDIA T400's 17,320. That is a delta of 80.3 percent in favor of AMD, meaning the RX 7600 delivers over five times the raw compute throughput in this workload. The gap narrows somewhat in Geekbench Vulkan, where the RX 7600 posts 34,401 versus the T400's 16,263, a 52.7 percent advantage. Even in its weaker benchmark, the AMD card still more than doubles the NVIDIA card's score.

The average benchmark scores tell a similar story, though the difference is less extreme. The T400 averages 16,792 across its recorded tests, while the RX 7600 averages 15,171. That places the T400 slightly ahead in aggregate, but this is misleading. The T400's average is built from only two benchmark entries, both of which are compute-oriented. The RX 7600's average draws from ten entries, including several legacy DirectX tests and 2D tests, which pull its mean downward. The head-to-head results, which use identical tests on both cards, are the more reliable indicator, and they show a decisive win for the RX 7600 in every shared metric.

Percentile rankings reinforce the positioning. The T400 sits at the 60th percentile of all GPUs in the database, while the RX 7600 sits at the 57th percentile. Despite the lower percentile, the RX 7600's nearest rivals include the NVIDIA GeForce RTX 3050 OEM, which averages 15,199, a delta of only 0.2 percent. The T400's nearest rivals cluster around 16,700 to 17,000, including the AMD Radeon RX 7600S at 16,696 and the NVIDIA Tesla M4 at 16,932. These rival groupings show that the T400 competes in a lower absolute performance tier, even though its percentile is marginally higher due to the smaller sample of tests.

Where Each One Wins

The RX 7600 wins every head-to-head benchmark in the database, so the use-case split is largely one-sided. For compute-heavy tasks such as OpenCL workloads, the RX 7600 is clearly superior. Its 88,051 OpenCL score versus 17,320 for the T400 indicates a massive advantage in general-purpose GPU compute. The Vulkan result, 34,401 versus 16,263, shows the AMD card also leads in modern graphics API performance, which matters for gaming and real-time rendering.

The T400's only statistical edge is its higher average benchmark score and its slightly better percentile ranking. Within its own benchmark set, the T400 achieves 17,320 in OpenCL and 16,263 in Vulkan, both respectable for a low-power workstation card. The T400 also has a narrower performance gap between its two recorded tests, suggesting more consistent behavior across different API types. However, the RX 7600's additional benchmark entries show strengths in specific legacy workloads: Passmark DirectX 9 at 226, DirectX 11 at 172, DirectX 10 at 84, and DirectX 12 at 58. The RX 7600 also records a Passmark G3D score of 16,634 and a GPU compute score of 8,790. These numbers indicate the RX 7600 handles a broader range of workloads, including older DirectX titles and 2D tasks, where it scores 984 in Passmark G2D.

For users focused purely on compute density per watt, the T400's 30 W power draw makes it viable in environments where the RX 7600's 165 W requirement is impractical. But in raw performance terms, there is no benchmark in the database where the T400 beats the RX 7600.

Architecture Differences

The two GPUs come from different architectural generations and design philosophies. The NVIDIA T400 uses the TU117 chip, built on the Turing architecture, and is part of the Quadro Turing generation. It is fabricated on a 12 nm process at TSMC, with 4,700 million transistors on a 200 mm² die. The transistor density works out to 23.5 million transistors per square millimeter. The RX 7600, by contrast, uses the Navi 33 chip on the RDNA 3.0 architecture, part of the Navi III (RX 7000) generation. It is built on a 6 nm process, also at TSMC, packing 13,300 million transistors into a 204 mm² die. That yields a density of 65.2 million transistors per square millimeter, nearly three times the density of the Turing chip.

The memory subsystems differ fundamentally. The T400 has 4 GB of GDDR6 on a 64-bit bus, delivering 80.00 GB/s of bandwidth. The RX 7600 has 8 GB of GDDR6 on a 128-bit bus, delivering 288.0 GB/s. The RX 7600's memory clock runs at 2250 MHz with 18 Gbps effective transfer, while the T400's memory runs at 1250 MHz with 10 Gbps effective. Wider bus and higher transfer rate give the RX 7600 3.6 times the memory bandwidth.

Compute resources also diverge sharply. The T400 has 384 shading units, 24 texture mapping units, and 16 raster output units. The RX 7600 has 2,048 shading units, 128 TMUs, and 64 ROPs. The RX 7600 also includes 32 ray tracing cores, a feature the T400 lacks entirely. The T400 has no tensor cores, and the RX 7600 also has no tensor cores, so neither card accelerates tensor workloads. Pixel and texture rates reflect the resource gap: the T400 achieves 22.80 GPixel/s and 34.20 GTexel/s, while the RX 7600 reaches 169.9 GPixel/s and 339.8 GTexel/s.

The RX 7600 supports DirectX 12 Ultimate (12_2), while the T400 supports DirectX 12 (12_1). Both cards support OpenGL 4.6 and Vulkan 1.4. The RX 7600's FP32 throughput is 21.75 TFLOPS with FP16 at the same rate (1:1). The T400 manages 1,094.4 GFLOPS in FP32 and 2.189 TFLOPS in FP16 with a 2:1 ratio. The RX 7600 thus has roughly 20 times the FP32 throughput and 10 times the FP16 throughput, though the FP16 comparison is complicated by the different ratio schemes.

Specification Differences

Clock speeds show a major divide. The T400 has a base clock of 420 MHz and a boost clock of 1425 MHz. The RX 7600 has a base clock of 1720 MHz, a game clock of 2250 MHz, and a boost clock of 2655 MHz. The RX 7600's boost clock is nearly double the T400's boost clock.

Power and physical requirements differ accordingly. The T400 draws 30 W and requires no power connectors, with a suggested power supply of 200 W. It is a single-slot card. The RX 7600 draws 165 W, uses a single 8-pin connector, and recommends a 450 W power supply. It is a dual-slot card. The RX 7600 measures 204 mm in length and 115 mm in height; the T400's dimensions are not recorded.

Bus interfaces differ. The T400 uses PCIe 3.0 x16, while the RX 7600 uses PCIe 4.0 x8. Display outputs also differ: the T400 offers three mini-DisplayPort 1.4a outputs, while the RX 7600 offers one HDMI 2.1a and three DisplayPort 2.1 outputs.

Production status separates the two. The T400 is end-of-life, released on 2021-05-05, with the Quadro Volta as its predecessor and Workstation Ampere as its successor. The RX 7600 is active, released on 2023-05-24, with Navi II as its predecessor and Navi IV as its successor. The RX 7600 has a launch MSRP of 269 USD; the T400 has no recorded launch MSRP.

The Verdict

The data is unambiguous. The AMD Radeon RX 7600 wins every recorded head-to-head benchmark against the NVIDIA T400 4 GB, with deltas of 80.3 percent in OpenCL and 52.7 percent in Vulkan. It offers more memory, more bandwidth, more shading units, ray tracing support, and a newer architecture on a smaller process node. Its only disadvantages are higher power draw, larger physical footprint, and a lower average benchmark score that results from including legacy tests in its dataset.

For users who need maximum compute performance, modern API support, or gaming capability, the RX 7600 is the clear choice. Its 21.75 TFLOPS of FP32 throughput and 288.0 GB/s of memory bandwidth place it in a completely different performance class. The 32 ray tracing cores add hardware acceleration that the T400 cannot offer.

For users constrained by power budgets or slot space, the T400 remains relevant. Its 30 W power draw requires no external power connectors and only a 200 W power supply, and its single-slot design fits in space-constrained systems. Its 60th percentile ranking, built on strong OpenCL and Vulkan scores for a card of its class, shows that it performs well within its intended workstation niche. But the T400 is end-of-life, and its 4 GB memory capacity is half that of the RX 7600.

The verdict follows the benchmark data: pick the RX 7600 for performance, pick the T400 only when power and space constraints override performance considerations.
