AMD Radeon RX 5600 XT vs AMD Radeon RX 7900 XTX Comparison

The AMD Radeon RX 5600 XT and AMD Radeon RX 7900 XTX represent two vastly different generations of AMD graphics technology, separated by a 2:1 ratio in transistor count and nearly three years of architectural evolution. The benchmark data shows a clear hierarchy, with the RX 7900 XTX winning 9 of 10 head-to-head tests, yet the RX 5600 XT claims a notable single victory that complicates the narrative. This analysis breaks down where each card excels, what the architecture differences mean in practice, and which GPU suits specific workloads.

Head-to-Head Benchmarks

The most dramatic margin in the entire dataset comes from the 3DMark Steel Nomad DX12 test. The RX 7900 XTX scores 6841, while the RX 5600 XT manages just 1669, a 75.6% deficit. This is the single largest performance gap observed, and it reflects the modern API advantage held by the newer architecture. In DirectX 12 workloads specifically, the RX 7900 XTX leads by 60.3%, posting 131 versus 52 in the Passmark DX12 test.

The RX 7900 XTX dominates the legacy DirectX suite as well. In Passmark DirectX 11, it scores 356 against the RX 5600 XT's 96, a 73% advantage. The DirectX 10 test shows a 56% gap (166 vs 73), and even the aging DirectX 9 benchmark favors the newer card by 38.8% (330 vs 202). These results suggest that the architectural improvements in RDNA 3.0 benefit even older APIs, not just modern titles.

Compute performance heavily favors the RX 7900 XTX. The Passmark GPU Compute test shows 17689 for the RX 7900 XTX versus 6296 for the RX 5600 XT, a 64.4% lead. The overall Passmark G3D score reinforces this pattern: 31238 vs 13457, a 56.9% advantage. Even the 2D test, which rarely stresses modern GPUs, shows a 31.3% gap (1267 vs 870).

The single win for the RX 5600 XT comes from Geekbench OpenCL, where it scores 68537 against 50465 for the RX 7900 XTX, a 35.8% margin. This is an outlier result that contradicts every other compute-heavy benchmark. In Geekbench Vulkan, the RX 7900 XTX reverses the trend decisively, scoring 85612 vs 56218, a 34.3% lead. The OpenCL result appears anomalous given the raw compute specifications, but it is the only test where the older card emerges victorious.

Architecture Differences

The RX 5600 XT uses the Navi 10 chip built on RDNA 1.0 architecture, fabricated on a 7 nm process at TSMC. It contains 10,300 million transistors across a 251 mm² die. The RX 7900 XTX uses Navi 31 on RDNA 3.0, fabricated on a 5 nm process, with 57,700 million transistors on a 529 mm² die. The node shrink from 7 nm to 5 nm enables the RX 7900 XTX to achieve a transistor density of 109.1M per mm², more than double the 41.0M per mm² of the older card.

The RX 5600 XT features 2304 shading units, 144 texture mapping units, and 64 render output units. It has no dedicated ray tracing cores. The RX 7900 XTX scales up dramatically with 6144 shading units, 384 TMUs, and 192 ROPs, plus 96 dedicated ray tracing cores. This represents a 2.67x increase in shading units and a 3x increase in both TMUs and ROPs.

Clock speeds tell a different story. The RX 5600 XT has a base clock of 1130 MHz and a boost clock of 1560 MHz, with a game clock of 1375 MHz. The RX 7900 XTX runs at 1929 MHz base and 2498 MHz boost, with a game clock of 2365 MHz. The newer card's higher clocks compound with its larger core configuration to produce 61.39 TFLOPS of FP32 performance, versus 7.188 TFLOPS for the RX 5600 XT.

Memory architecture diverges sharply. The RX 5600 XT uses 6 GB of GDDR6 on a 192-bit bus, delivering 288.0 GB/s bandwidth. The RX 7900 XTX uses 24 GB of GDDR6 on a 384-bit bus, quadrupling the bus width and delivering 960.0 GB/s bandwidth. The effective memory clock rises from 12 Gbps to 20 Gbps. Both cards support PCIe 4.0 x16.

Specification Differences

The RX 7900 XTX draws 355 W TDP versus 150 W for the RX 5600 XT, requiring a 750 W suggested PSU versus 450 W. Power delivery changes from a single 8-pin connector to dual 8-pin connectors. The RX 7900 XTX is longer at 287 mm (11.3 inches) versus 267 mm (10.5 inches), and adds height (110 mm) and width (51 mm) dimensions that the RX 5600 XT does not list.

Display outputs differ significantly. The RX 5600 XT offers one HDMI 2.0b port and three DisplayPort 1.4a outputs. The RX 7900 XTX provides one HDMI 2.1a port, two DisplayPort 2.1 outputs, and one USB Type-C port. The RX 7900 XTX supports DirectX 12 Ultimate (12_2), while the RX 5600 XT is limited to DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4.

Where Each One Wins

The RX 5600 XT wins in exactly one measurable area: Geekbench OpenCL compute. Its score of 68537 exceeds the RX 7900 XTX by 35.8%. This suggests certain OpenCL workloads may favor the older card's architecture, though the broader compute picture strongly favors the RX 7900 XTX. The RX 5600 XT also holds a higher average benchmark score (20713 vs 19410) and a higher percentile rank among all GPUs (66 vs 64).

The RX 7900 XTX wins everywhere else. Its 3DMark Steel Nomad DX12 score of 6841 dwarfs the RX 5600 XT's 1669. It leads in every Passmark test: DirectX 9 (330 vs 202), DirectX 10 (166 vs 73), DirectX 11 (356 vs 96), DirectX 12 (131 vs 52), G2D (1267 vs 870), G3D (31238 vs 13457), and GPU Compute (17689 vs 6296). In Geekbench Vulkan, it scores 85612 against 56218.

For gaming at high resolutions or with ray tracing enabled, the RX 7900 XTX is the clear choice. Its 96 ray tracing cores and 24 GB of VRAM provide headroom that the RX 5600 XT cannot match. For 1080p esports titles or older DirectX 9/10 games, the RX 5600 XT's lower power draw and smaller footprint may suffice, though it still loses those API benchmarks to the RX 7900 XTX.

The Verdict

The data presents a lopsided contest. The RX 7900 XTX wins 9 of 10 head-to-head benchmarks, with margins ranging from 31.3% to 75.6%. Its architectural advantages are overwhelming: 2.67x more shading units, 3x more TMUs and ROPs, 8.5x more FP32 throughput, and 3.33x more memory bandwidth. The RX 5600 XT's lone OpenCL victory and higher average score are statistical curiosities, not indicators of general superiority.

Users seeking maximum performance in modern DirectX 12 titles, ray-traced workloads, or compute-heavy applications should choose the RX 7900 XTX. Its 24 GB VRAM and 960.0 GB/s bandwidth make it suitable for demanding resolutions and large datasets. The 355 W TDP and dual 8-pin connectors require a robust power supply, but the performance justifies the infrastructure.

Users constrained by power, space, or older software ecosystems may find the RX 5600 XT acceptable. Its 150 W TDP and single 8-pin connector fit into smaller builds, and its 267 mm length is more compact. The 6 GB VRAM limits its future-proofing, and its lack of ray tracing cores means it cannot handle modern RT workloads. For those users, the RX 5600 XT remains a functional legacy option, but the RX 7900 XTX dominates in every meaningful metric for current and future software.
