AMD Radeon RX 6700 XT vs NVIDIA RTX A4000 Comparison

The AMD Radeon RX 6700 XT and NVIDIA RTX A4000 represent two distinct philosophies in the GPU market: one built for high-refresh gaming, the other for professional workstation tasks. While both cards target the same performance percentile — each sits at the 72nd percentile of all GPUs — their benchmark profiles reveal starkly different strengths. The data shows a split decision: the NVIDIA RTX A4000 wins 6 of 10 head-to-head tests, but the AMD card takes the remaining 4, including several DirectX legacy tests. Their average benchmark scores differ by only 2.7% (27,425 for the RX 6700 XT versus 26,683 for the RTX A4000), making this a closer contest than raw specifications might suggest.

Head-to-Head Benchmarks

The most dramatic divergence appears in compute-oriented workloads. In Geekbench OpenCL, the RTX A4000 scores 105,739 against the RX 6700 XT’s 44,152 — a 58.2% advantage. This is the single largest margin in the comparison and highlights the NVIDIA card’s raw compute throughput. The RTX A4000 also dominates in Geekbench Vulkan, posting 127,645 versus 93,500, a 26.7% lead. Even in the modern DirectX 12 workload of 3DMark Steel Nomad, the NVIDIA card wins by 6.5% (2,604 vs. 2,435). The pattern is consistent: the RTX A4000 excels in API-heavy and compute-centric scenarios.

The RX 6700 XT fights back in older DirectX tests. In PassMark DirectX 11, it wins 173 to 158, a 9.5% margin. In PassMark DirectX 12, the margin is 6.9% (77 vs. 72). The AMD card also edges out the NVIDIA card in PassMark DirectX 9 (242 vs. 240, a 0.8% difference) and PassMark G3D (19,786 vs. 19,459, a 1.7% lead). These wins are narrower than the RTX A4000’s compute victories, but they demonstrate that the RX 6700 XT retains a competitive edge in rasterization-based synthetic tests.

The remaining tests split closely. The RTX A4000 wins PassMark G2D by 7.1% (1,024 vs. 951) and PassMark GPU Compute by 4.3% (9,760 vs. 9,336). PassMark DirectX 10 is nearly a tie, with the NVIDIA card ahead by just 1.6% (126 vs. 124). Notably, the RX 6700 XT’s nearest rival is the NVIDIA GeForce RTX 3090, with a delta of only -0.5% — meaning the AMD card essentially matches a flagship-class GPU in average score. The RTX A4000, by contrast, sits just 0.5% ahead of the AMD Radeon RX 5700 XT 50th Anniversary, indicating its average performance is closer to mid-range territory.

Architecture Differences

The two cards are built on fundamentally different architectures and manufacturing processes. The RX 6700 XT uses AMD’s RDNA 2.0 architecture on a 7 nm TSMC process, with 17,200 million transistors on a 335 mm² die. The RTX A4000 employs NVIDIA’s Ampere architecture on an 8 nm Samsung process, packing 17,400 million transistors into a larger 392 mm² die. The AMD chip achieves a higher transistor density (51.3M per mm²) versus the NVIDIA chip’s 44.4M per mm².

Clock speeds tell an even more divergent story. The RX 6700 XT runs at a base clock of 2321 MHz and boosts to 2581 MHz, with a game clock of 2424 MHz. The RTX A4000 operates at a far lower 735 MHz base and 1560 MHz boost. Despite the massive clock advantage for AMD, the RTX A4000 delivers higher FP32 throughput (19.17 TFLOPS vs. 13.21 TFLOPS) because it packs 6,144 shading units versus 2,560 on the AMD card. The NVIDIA card also has more TMUs (192 vs. 160) and ROPs (96 vs. 64).

Memory configurations differ substantially. The RTX A4000 offers 16 GB of GDDR6 on a 256-bit bus, yielding 448.0 GB/s bandwidth. The RX 6700 XT provides 12 GB of GDDR6 on a 192-bit bus, with 384.0 GB/s bandwidth. The NVIDIA card’s memory runs at 1750 MHz (14 Gbps effective), while the AMD card’s memory runs at 2000 MHz (16 Gbps effective). The RTX A4000 also includes 192 tensor cores and 48 RT cores, whereas the RX 6700 XT has 40 RT cores and no tensor cores. Power consumption is another clear differentiator: the RTX A4000 draws 140 W TDP with a 300 W suggested PSU, while the RX 6700 XT draws 230 W with a 550 W suggested PSU.

Transistor counts are close (17,200 million vs. 17,400 million), but die size differs significantly (335 mm² vs. 392 mm²). Clock speeds are radically different: the AMD card has a 2321 MHz base and 2581 MHz boost, while the NVIDIA card has a 735 MHz base and 1560 MHz boost.

Memory specs diverge: the RX 6700 XT has 12 GB on a 192-bit bus with 384.0 GB/s; the RTX A4000 has 16 GB on a 256-bit bus with 448.0 GB/s. The AMD card has 2,560 shading units, 160 TMUs, 64 ROPs, and 40 RT cores. The NVIDIA card has 6,144 shading units, 192 TMUs, 96 ROPs, 48 RT cores, and 192 tensor cores. Pixel rate favors the AMD card (165.2 GPixel/s vs. 149.8 GPixel/s), but texture rate is higher on NVIDIA’s card (299.5 GTexel/s vs. 413.0 GTexel/s — wait, this is reversed: the RX 6700 XT has 413.0 GTexel/s). FP32 performance favors NVIDIA (19.17 TFLOPS vs. 13.21 TFLOPS), as does FP16 performance (19.17 TFLOPS vs. 26.43 TFLOPS — the AMD card actually has higher FP16). The RTX A4000 has a 140 W TDP versus 230 W, is single-slot versus dual-slot, uses 1x 6-pin versus 1x 6-pin + 1x 8-pin, and requires a 300 W PSU versus 550 W. Display outputs differ: AMD offers 1x HDMI 2.1 and 3x DisplayPort 1.4a, while NVIDIA offers 4x DisplayPort 1.4a. The RX 6700 XT is 267 mm long; the RTX A4000 is 241 mm long.

The Verdict

The data paints a clear picture for different use cases. The NVIDIA RTX A4000 is the choice for compute-heavy workloads. Its 58.2% lead in Geekbench OpenCL and 26.7% lead in Geekbench Vulkan are decisive, and its 6.5% advantage in 3DMark Steel Nomad shows modern API strength. The card’s 16 GB memory and 448.0 GB/s bandwidth provide more capacity for large datasets, while its 140 W TDP and single-slot design make it far easier to integrate into dense workstation builds.

The AMD Radeon RX 6700 XT is better suited for legacy and rasterization-focused tasks. Its wins in PassMark DirectX 11 and DirectX 12 — by 9.5% and 6.9%, respectively — indicate strong performance in older APIs that remain common in gaming and some productivity applications. The card’s higher pixel rate (165.2 GPixel/s vs. 149.8 GPixel/s) and texture rate (413.0 GTexel/s vs. 299.5 GTexel/s) support its PassMark G3D victory by 1.7%.

For users prioritizing raw compute throughput, memory capacity, and power efficiency, the RTX A4000 is the data-backed choice. For those working primarily with DirectX 11/12 gaming workloads or legacy applications, the RX 6700 XT offers measurable advantages. The RX 6700 XT also holds a slight edge in average score (27,425 vs. 26,683), but the RTX A4000’s wins are more concentrated in professional-grade compute scenarios. Both cards sit at the 72nd percentile of all GPUs, meaning either will handle mainstream tasks competently — but their strengths do not overlap. Choose based on the specific benchmark profile that matches your workload.
