AMD Radeon Pro 460 vs AMD Radeon RX 7900 XTX Comparison

Head-to-Head Benchmarks

The recorded data contains two direct head-to-head benchmark comparisons between the AMD Radeon RX 7900 XTX and the AMD Radeon Pro 460. In both tests, the RX 7900 XTX emerges as the winner, with margins that are substantial by any measure.

In Geekbench OpenCL, the RX 7900 XTX scores 50,465 points against the Radeon Pro 460's 15,284 points. This represents a delta of 230.2%, meaning the RX 7900 XTX delivers more than triple the compute performance in this workload. The OpenCL test is particularly relevant for general-purpose GPU compute tasks, and the gap reflects the fundamental differences in raw throughput between these two products.

The Geekbench Vulkan test shows an even larger divide. The RX 7900 XTX posts 85,612 points, while the Radeon Pro 460 manages 16,816 points. The delta here is 409.1%, meaning the RX 7900 XTX is roughly five times faster in this graphics API workload. Vulkan is a low-level API that exposes the hardware more directly, so this result indicates the RX 7900 XTX's architectural efficiency and raw resources translate into a commanding lead in modern graphics workloads.

Looking at the broader benchmark picture, the RX 7900 XTX holds an average benchmark score of 19,410 across all its recorded tests, which includes direct 3DMark Steel Nomad DX12, multiple Passmark tests, and Geekbench workloads. The Radeon Pro 460's average score is 17,509 across its three recorded Geekbench tests. Interestingly, the average scores are closer than the head-to-head deltas might suggest, because the RX 7900 XTX's benchmark suite includes several Passmark tests with lower absolute scores that pull its average down. The percentile rankings reinforce this: the RX 7900 XTX sits at the 64th percentile among all GPUs, while the Radeon Pro 460 sits at the 61st percentile.

The RX 7900 XTX's nearest rivals in the database, based on average benchmark score, include the NVIDIA GeForce GTX 1060 3 GB (delta of 0.4%), the NVIDIA Quadro K5200 (delta of -1%), the AMD FirePro D300 (delta of -1.2%), and the NVIDIA TITAN Xp (delta of 1.2%). This places the RX 7900 XTX in a cluster where its average score is within about one percent of several very different products. The Radeon Pro 460's nearest rivals include the NVIDIA Tesla K40c (delta of 0.2%), the AMD Radeon Pro 560 (delta of -0.2%), the AMD Radeon 780M (delta of -0.5%), and the NVIDIA GeForce RTX 4060 (delta of -0.7%). The Radeon Pro 460 is thus grouped with a mix of workstation and consumer parts whose average scores are all within about one percent of its own.

The Verdict

The data points to a clear conclusion: the AMD Radeon RX 7900 XTX is the superior performer in every measured head-to-head test. The RX 7900 XTX wins both Geekbench OpenCL and Geekbench Vulkan with deltas of 230.2% and 409.1% respectively. Anyone selecting between these two cards strictly on the basis of benchmark scores should choose the RX 7900 XTX without hesitation.

However, the database also shows that these are fundamentally different products with different intended use cases. The Radeon Pro 460, with its 35 W power envelope and IGP slot width, is designed for portable systems where power consumption and physical space are the primary constraints. Its 14.51 GPixel/s pixel rate and 58.05 GTexel/s texture rate are modest figures, but they are achieved within a power budget that the RX 7900 XTX cannot approach.

The RX 7900 XTX, by contrast, is an end-of-life enthusiast part that demands a 750 W suggested power supply and dual-slot physical space. Its 479.6 GPixel/s pixel rate and 959.2 GTexel/s texture rate represent a generational leap over the Radeon Pro 460, but those figures come with a 355 W TDP and a 51 mm width. The recorded dimensions of 287 mm in length make it incompatible with the compact chassis that would house the Radeon Pro 460.

From the data, the RX 7900 XTX is the choice for users who need maximum compute and graphics throughput and have the system capacity to support it. The Radeon Pro 460 is the choice for users who need a low-power GPU for a portable or space-constrained system, accepting a fraction of the performance. The two cards occupy different tiers of the product stack, and the benchmark data simply reflects that positioning.

Architecture Differences

The two GPUs are separated by multiple architectural generations. The RX 7900 XTX uses the Navi 31 chip built on the RDNA 3.0 architecture, codenamed Plum Bonito, and belongs to the Navi III (RX 7000) generation. The Radeon Pro 460 uses the Baffin chip built on the GCN 4.0 architecture and belongs to the Radeon Pro Mac (400 Series) generation.

The manufacturing process differs substantially. The RX 7900 XTX is fabricated on a 5 nm process at TSMC, while the Radeon Pro 460 uses a 14 nm process at GlobalFoundries. This process gap contributes heavily to the transistor density difference: the RX 7900 XTX packs 57,700 million transistors into a 529 mm² die, yielding a density of 109.1M transistors per mm². The Radeon Pro 460 contains 3,000 million transistors on a 123 mm² die, with a density of 24.4M per mm². The RX 7900 XTX thus has roughly 19 times the transistor count on about 4.3 times the die area.

Ray tracing support is another major architectural divider. The RX 7900 XTX includes 96 dedicated ray tracing cores, while the Radeon Pro 460 has no ray tracing cores listed. Neither card has tensor cores recorded in the database.

The shader and texture resources are in entirely different leagues. The RX 7900 XTX has 6,144 shading units, 384 texture mapping units, and 192 render output units. The Radeon Pro 460 has 1,024 shading units, 64 TMUs, and 16 ROPs. The RX 7900 XTX therefore has six times the shading units, six times the TMUs, and twelve times the ROPs.

The floating-point capabilities reflect these resource differences. The RX 7900 XTX delivers 61.39 TFLOPS of FP32 performance and 122.8 TFLOPS of FP16 performance at a 2:1 ratio. The Radeon Pro 460 delivers 1.858 TFLOPS of FP32 and 1.858 TFLOPS of FP16 at a 1:1 ratio, meaning it has no accelerated half-precision path.

API support also differs. The RX 7900 XTX supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, while the Radeon Pro 460 supports DirectX 12 (12_0) and Vulkan 1.3. Both cards support OpenGL 4.6. The RX 7900 XTX's newer API versions reflect its more modern architecture and feature set.

Specification Differences

The memory subsystems are very different. The RX 7900 XTX has 24 GB of GDDR6 memory on a 384-bit bus, delivering 960.0 GB/s of bandwidth. The Radeon Pro 460 has 4 GB of GDDR5 memory on a 128-bit bus, delivering 81.28 GB/s. The RX 7900 XTX therefore offers six times the memory capacity and roughly 11.8 times the memory bandwidth.

Clock speeds differ substantially. The RX 7900 XTX runs at a base clock of 1929 MHz, a boost clock of 2498 MHz, and a game clock of 2365 MHz. Its memory operates at 2500 MHz with 20 Gbps effective data rate. The Radeon Pro 460 runs at a base clock of 850 MHz and a boost clock of 907 MHz, with memory at 1270 MHz and 5.1 Gbps effective. The RX 7900 XTX's boost clock is 2.75 times higher than the Radeon Pro 460's.

Power and physical specifications set these cards apart as completely different product categories. The RX 7900 XTX has a TDP of 355 W, a dual-slot form factor, two 8-pin power connectors, and a suggested PSU of 750 W. The Radeon Pro 460 has a TDP of 35 W, an IGP slot width, no power connectors, and no suggested PSU listed. The RX 7900 XTX measures 287 mm in length, 110 mm in height, and 51 mm in width. The Radeon Pro 460 has no dimensions listed, consistent with its integration into portable devices.

The bus interface also differs: the RX 7900 XTX uses PCIe 4.0 x16, while the Radeon Pro 460 uses PCIe 3.0 x8. Display outputs reflect their different markets: the RX 7900 XTX offers 1x HDMI 2.1a, 2x DisplayPort 2.1, and 1x USB Type-C, while the Radeon Pro 460's outputs are listed as portable device dependent.

Release timing places the RX 7900 XTX at 2022-11-02 and the Radeon Pro 460 at 2016-10-29. The RX 7900 XTX lists a predecessor of Navi II and a successor of Navi IV, while the Radeon Pro 460 has no predecessor or successor recorded. Both cards are end-of-life in production status.

Where Each One Wins

The RX 7900 XTX wins every head-to-head benchmark in the database. In Geekbench OpenCL, it leads by 230.2%, and in Geekbench Vulkan by 409.1%. Its wins extend across the entire recorded benchmark suite: it posts 6,841 points in 3DMark Steel Nomad DX12, 50,465 in Geekbench OpenCL, 85,612 in Geekbench Vulkan, and strong Passmark scores including 31,238 in G3D and 17,689 in GPU Compute. The architecture's 61.39 TFLOPS FP32 throughput and 479.6 GPixel/s pixel rate make it suitable for demanding 3D rendering, compute workloads, and high-resolution gaming, assuming the system can supply 355 W and accommodate a 287 mm dual-slot card.

The Radeon Pro 460's recorded strengths are more modest but relevant to its niche. Its 35 W TDP and IGP form factor make it suitable for portable systems where the RX 7900 XTX physically cannot fit. Its 1.858 TFLOPS FP32 and FP16 performance at a 1:1 ratio means it handles half-precision workloads at the same rate as full-precision, which can be relevant for certain compute tasks. Its Geekbench Metal score of 20,426, a benchmark not recorded for the RX 7900 XTX, indicates some level of graphics capability within Apple's Metal API, consistent with its Radeon Pro Mac generation labeling. The Radeon Pro 460's nearest rival cluster, which includes the AMD Radeon 780M and NVIDIA GeForce RTX 4060 with deltas under one percent, shows it performs in line with modern integrated and entry-level discrete solutions.

The use-case split is therefore clear. The RX 7900 XTX is for users who need maximum throughput in OpenCL, Vulkan, DirectX 12, and general compute, and who have the power delivery and physical space to support it. The Radeon Pro 460 is for users in portable Mac systems who need a low-power GPU with no external power connectors, and who accept a much lower performance ceiling. The data does not suggest these cards compete for the same buyer; it shows two products engineered for different constraints, with the RX 7900 XTX dominating in pure performance and the Radeon Pro 460 offering a viable low-power alternative in its own segment.
