AMD Radeon RX 7600 XT vs NVIDIA T400 4 GB Comparison

# AMD Radeon RX 7600 XT vs NVIDIA T400 4 GB

The AMD Radeon RX 7600 XT is decisively faster than the NVIDIA T400 4 GB across every shared benchmark, but these two cards target entirely different workloads. The RX 7600 XT wins both head-to-head tests by margins of 433.6% and 197.4%, yet the T400 remains relevant for low-power, single-slot environments where its 30 W TDP and lack of external power connectors matter more than raw compute. The data shows a 60th-percentile ranking for both cards, but that percentile masks a chasm in performance class — the RX 7600 XT is an active-production gaming GPU, while the T400 is an end-of-life workstation card from the Quadro Turing generation.

Where Each One Wins

The RX 7600 XT wins in every measurable compute category. In Geekbench OpenCL, it scores 92,426 against the T400's 17,320 — a 433.6% advantage that reflects the AMD card's 2,048 shading units versus 384 on the T400. In Geekbench Vulkan, the RX 7600 XT posts 48,366 versus 16,263, a 197.4% lead. These are not close contests; the AMD card delivers roughly five times the OpenCL throughput and three times the Vulkan performance.

The T400's wins are structural rather than computational. It is a single-slot card with no power connectors and a 30 W TDP, making it suitable for compact workstations or dense server environments where the RX 7600 XT's dual-slot footprint and 190 W TDP would be prohibitive. The T400 also uses PCIe 3.0 x16, which provides more lanes than the RX 7600 XT's PCIe 4.0 x8 — though the AMD card's newer bus standard offers higher per-lane bandwidth. For display output, the T400 offers three mini-DisplayPort 1.4a connections, while the RX 7600 XT provides one HDMI 2.1a and three DisplayPort 2.1 outputs, giving the AMD card a more modern and versatile display interface.

Architecture Differences

The architectural gap is generational and fundamental. The RX 7600 XT uses the Navi 33 chip on TSMC's 6 nm process, packing 13,300 million transistors into a 204 mm² die for a density of 65.2M transistors per mm². The T400 uses the TU117 chip on TSMC's 12 nm process, with 4,700 million transistors on a 200 mm² die — a density of just 23.5M per mm². The RX 7600 XT's RDNA 3.0 architecture is built for modern gaming workloads, supporting DirectX 12 Ultimate (12_2), while the T400's Turing architecture only reaches DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4.

The compute resources differ by an order of magnitude. The RX 7600 XT has 2,048 shading units, 128 texture mapping units, 64 ROPs, and 32 ray tracing cores. The T400 has 384 shading units, 24 TMUs, and 16 ROPs — no ray tracing cores at all. Pixel rate on the AMD card is 176.3 GPixel/s versus 22.80 GPixel/s on the T400. Texture rate is 352.6 GTexel/s versus 34.20 GTexel/s. FP32 throughput is 22.57 TFLOPS versus 1,094.4 GFLOPS. The RX 7600 XT even matches its FP16 performance at a 1:1 ratio, while the T400's FP16 runs at 2:1 with 2.189 TFLOPS.

Memory architecture reinforces the gap. The RX 7600 XT carries 16 GB of GDDR6 on a 128-bit bus, delivering 288.0 GB/s bandwidth. The T400 has 4 GB of GDDR6 on a 64-bit bus, yielding 80.00 GB/s. Clock speeds also favor AMD: the RX 7600 XT boosts to 2755 MHz with a 2470 MHz game clock, while the T400 boosts to just 1425 MHz from a 420 MHz base. The T400's memory runs at 1250 MHz (10 Gbps effective) versus the AMD card's 2250 MHz (18 Gbps effective).

The Verdict

Choose the RX 7600 XT for any task where compute performance matters. It dominates the T400 by 433.6% in OpenCL and 197.4% in Vulkan, offers 16 GB of memory versus 4 GB, and supports modern features like ray tracing and DirectX 12 Ultimate. Its 60th-percentile ranking among all GPUs places it near the NVIDIA GeForce RTX 3070 (average score 17,208, delta -0.7%) and ahead of the GTX 690 (17,037, +0.3%) — a solid mid-range gaming and content creation card.

Choose the T400 only for constrained environments where its 30 W TDP, single-slot design, and lack of power connectors are decisive. It is end-of-life, with only 4 GB of memory and no ray tracing support, but its 60th-percentile ranking matches the RX 7600 XT's percentile — a reminder that percentile reflects the entire GPU population, including far weaker cards. The T400's nearest rivals include the AMD Radeon RX 7600S (average 16,696, +0.6%) and the NVIDIA Tesla M4 (16,932, -0.8%), showing it sits in a performance tier near low-end mobile GPUs, not desktop gaming cards.

FAQ

Q: Which card has higher raw compute performance?

A: The RX 7600 XT is overwhelmingly faster, with 22.57 TFLOPS FP32 versus 1,094.4 GFLOPS on the T400. In Geekbench OpenCL, the AMD card scores 92,426 versus 17,320, a 433.6% advantage.

Head-to-Head Benchmarks

The Geekbench OpenCL result is the single largest gap between these two cards. The RX 7600 XT's 92,426 score dwarfs the T400's 17,320, producing a delta of 433.6%. This result aligns with the FP32 throughput difference — 22.57 TFLOPS versus 1.094 TFLOPS — and the shading unit count of 2,048 versus 384. The OpenCL test stresses general compute, where the AMD card's RDNA 3.0 architecture and higher clock speeds (2755 MHz boost versus 1425 MHz) compound the hardware advantage.

The Vulkan benchmark narrows the gap slightly but remains lopsided. The RX 7600 XT scores 48,366 against the T400's 16,263, a 197.4% lead. Vulkan's lower overhead may benefit the T400's simpler Turing architecture, but the AMD card still delivers roughly triple the performance. The RX 7600 XT's 32 ray tracing cores and DirectX 12 Ultimate support suggest it is better equipped for modern graphics APIs, while the T400's lack of RT cores limits its Vulkan feature set.

In the broader context of the nearestRivals data, the RX 7600 XT's average benchmark score of 17,083 places it just 0.3% above the NVIDIA GeForce GTX 690 (17,037) and 0.4% above the AMD Radeon HD 7970M (17,019). It trails the RTX 3070 (17,208) by 0.7%. The T400's average score of 16,792 sits 0.6% below the RX 7600S (16,696) and 0.8% below the Tesla M4 (16,932). Notably, both cards share the Tesla M4 as a rival, but the RX 7600 XT beats it by 0.9% while the T400 trails it by 0.8% — a 1.7-point swing that underscores the performance hierarchy.
