AMD Radeon RX 7600S vs NVIDIA Quadro RTX 4000 Comparison

The NVIDIA Quadro RTX 4000 and AMD Radeon RX 7600S are separated by five years of silicon evolution, yet the benchmark data shows a surprisingly competitive matchup. The AMD part wins six of the ten head-to-head tests, but the NVIDIA card takes the most decisive victories, creating a profile that is less about overall superiority and more about divergent strengths. The data indicates that the newer, lower-power AMD chip trades blows with an older desktop-class workstation GPU, with the final choice depending heavily on the specific workload.

Head-to-Head Benchmarks

The most striking outcome is in the legacy DirectX 10 test, where the NVIDIA Quadro RTX 4000 delivers a crushing 45.9% lead over the AMD Radeon RX 7600S (108 vs. 74). This is the single largest delta in the entire comparison, suggesting NVIDIA’s architecture retains a significant advantage in older API workloads, a critical consideration for legacy enterprise applications. The Quadro also shows substantial leads in compute and API-agnostic tests: it posts a 9.6% win in Geekbench OpenCL (74540 vs. 68012) and a 6.7% win in Geekbench Vulkan (78844 vs. 73868). The 9% advantage in Passmark G2D (846 vs. 776) further cements its strength in 2D and user-interface rendering tasks.

The AMD Radeon RX 7600S, however, wins the modern and synthetic tests. It edges out the Quadro by a narrow 0.8% in 3DMark Steel Nomad DX12 (1888 vs. 1873), showing near parity in the latest DirectX 12 rasterization workload. The AMD chip’s most emphatic win comes in Passmark DirectX 12, where it scores 65 against the Quadro’s 52, a 20% advantage. It also leads in Passmark DirectX 11 by 8.6% (140 vs. 128) and in the older DirectX 9 test by 2.8% (211 vs. 205). In the aggregate gaming metric, Passmark G3D, the RX 7600S is 1.9% ahead (15408 vs. 15117), and it also wins the GPU compute test by 5.3% (6520 vs. 6176). This split suggests the AMD card is tuned for modern gaming APIs, while the NVIDIA part holds its own in professional and legacy scenarios.

Architecture Differences

The architectural divide is stark. The NVIDIA Quadro RTX 4000 is built on the Turing architecture using a 12 nm process at TSMC, featuring a massive 545 mm² die with 13,600 million transistors. In contrast, the AMD Radeon RX 7600S leverages the newer RDNA 3.0 architecture on a 6 nm process, also at TSMC, but with a much smaller 204 mm² die containing 13,300 million transistors. This results in a transistor density of 25.0M per mm² for NVIDIA versus 65.2M per mm² for AMD, highlighting the efficiency gains of the newer manufacturing node.

The compute configuration diverges significantly. The Quadro RTX 4000 carries 2304 shading units, 144 TMUs, and 64 ROPs, along with dedicated hardware: 36 RT cores and 288 tensor cores. The RX 7600S, by contrast, has fewer shading units (1792) and TMUs (112), but maintains the same 64 ROPs. It also has 28 RT cores but lacks tensor cores entirely. Clock speeds tell a different story: the AMD chip has a base clock of 1500 MHz and a boost of 2200 MHz, while the NVIDIA part runs at a much lower 1005 MHz base and 1545 MHz boost. This clock advantage, combined with the RDNA 3.0 design, allows the RX 7600S to achieve a higher FP32 throughput of 15.77 TFLOPS compared to the Quadro’s 7.119 TFLOPS. Memory configurations also differ: both have 8 GB of GDDR6, but the Quadro uses a 256-bit bus for 416.0 GB/s bandwidth, while the RX 7600S is limited to a 128-bit bus and 256.0 GB/s.

Specification Differences

The two cards differ across nearly every core specification. The NVIDIA Quadro RTX 4000 uses the TU104 chip on a 12 nm process, while the AMD Radeon RX 7600S uses the Navi 33 chip on a 6 nm process. Die size differs massively: 545 mm² for NVIDIA versus 204 mm² for AMD. Clock speeds are higher on the AMD card, with a 1500 MHz base and 2200 MHz boost, compared to 1005 MHz and 1545 MHz for the NVIDIA card. The memory bus width is 256-bit for the Quadro and 128-bit for the RX 7600S, leading to different bandwidth figures of 416.0 GB/s and 256.0 GB/s. The shading unit count is 2304 for NVIDIA and 1792 for AMD, while TMUs number 144 and 112, respectively. The TDP is 160 W for the Quadro and 75 W for the RX 7600S. The Quadro is a single-slot card with a 1x 8-pin power connector and requires a 450 W power supply, while the RX 7600S is an IGP with no power connectors. The bus interface is PCIe 3.0 x16 for the Quadro and PCIe 4.0 x16 for the AMD card. The Quadro has 288 tensor cores, while the RX 7600S has none.

The Verdict

The data suggests two distinct buyer profiles. The NVIDIA Quadro RTX 4000 is the choice for users prioritizing legacy API performance and higher memory bandwidth. Its 45.9% lead in DirectX 10 and 9.6% lead in OpenCL make it a stronger candidate for older professional software and compute workloads that rely on these interfaces. Its 416.0 GB/s bandwidth is more than adequate for data-heavy tasks, and its 288 tensor cores offer hardware acceleration for AI inference that the AMD card lacks entirely.

The AMD Radeon RX 7600S is the better option for modern gaming and efficiency-focused systems. It wins the Passmark G3D aggregate gaming score and dominates the Passmark DirectX 12 test by 20%. Its 75 W TDP is less than half that of the Quadro, making it suitable for thin-and-light laptops with no dedicated power connectors. The higher clock speeds and FP32 throughput of 15.77 TFLOPS also indicate superior raw compute potential for modern, multi-threaded workloads.

Where Each One Wins

NVIDIA Quadro RTX 4000 wins in scenarios involving older APIs and high-bandwidth data movement. The 45.9% DirectX 10 victory is a decisive advantage for compatibility with legacy enterprise applications. The 9.6% OpenCL lead and 9% G2D win make it a better fit for professional 2D design, video editing, and general compute tasks that leverage OpenCL. The 256-bit memory bus provides 416.0 GB/s of bandwidth, which is critical for large dataset manipulation. Its 288 tensor cores also give it a distinct edge in AI-accelerated workloads, even if raw benchmark scores don’t directly show it.

AMD Radeon RX 7600S wins in modern gaming and power-constrained environments. The 20% lead in Passmark DirectX 12 and the 8.6% lead in DirectX 11 show it is better optimized for current game engines. The 1.9% win in Passmark G3D confirms its overall gaming superiority. The 5.3% win in Passmark GPU Compute and 0.8% win in 3DMark Steel Nomad further indicate strong modern performance. With a 75 W TDP, this is the clear winner for portable devices where power efficiency is paramount. The 6 nm process and smaller die size also suggest a more modern, thermally efficient design, even if the Quadro’s larger die offers more raw memory bandwidth.
