AMD Radeon Pro 5500 XT vs NVIDIA GeForce GTX TITAN X Comparison

AMD Radeon Pro 5500 XT vs NVIDIA GeForce GTX TITAN X presents a clear generational clash, pairing a modern 7 nm RDNA 1.0 part against a 28 nm Maxwell 2.0 flagship from the GeForce 900 era. The recorded data shows two very different design philosophies: the AMD card leans on architectural efficiency and modern API performance, while the NVIDIA card counters with raw compute throughput and a wider memory bus. Benchmark results indicate that neither card dominates outright, and the choice between them depends heavily on which workload and API matters most.

Head-to-Head Benchmarks

The most dramatic separation in the database appears in the Geekbench Metal test. The AMD Radeon Pro 5500 XT scores 54779 points, while the NVIDIA GeForce GTX TITAN X manages only 18723 points. That is a 192.6% advantage for the AMD card, a massive margin that reflects both the age of the Maxwell architecture and the relative weakness of NVIDIA's Metal driver path on this older GPU. For any Mac-centric Metal workload, the data is unambiguous: the Radeon Pro 5500 XT is in a different performance class.

The Geekbench OpenCL test tells a much tighter story. Here the AMD card scores 41772, narrowly edging out the NVIDIA card's 41471. The delta is just 0.7%, which is effectively a statistical tie in practical terms. Both GPUs land within a hair of each other in raw OpenCL compute, despite the NVIDIA card having nearly double the shading units, 3072 versus 1536, and a substantially higher FP32 rating of 6.691 TFLOPS versus 5.398 TFLOPS. The AMD architecture extracts more usable throughput per shader, or at least per clock, and that efficiency closes the gap that raw specifications would suggest.

The Vulkan test flips the script. The NVIDIA GeForce GTX TITAN X scores 49397, while the AMD Radeon Pro 5500 XT scores 39601. That gives NVIDIA a 19.8% lead, the second-largest margin in this comparison. This result is notable because both cards report Vulkan 1.4 support in the database, yet the NVIDIA implementation delivers meaningfully higher performance. The younger RDNA 1.0 architecture does not automatically translate into a Vulkan win, and the GTX TITAN X demonstrates that its Maxwell compute resources still respond well to a low-level API.

Overall, the AMD card wins two of the three head-to-head tests, but the magnitude of those wins is lopsided. Its Metal victory is overwhelming, its OpenCL victory is negligible, and its Vulkan loss is substantial. The NVIDIA card's single Vulkan win is decisive enough to keep the comparison competitive for certain users. The average benchmark scores reflect this split: the AMD card averages 45384 across all recorded tests, while the NVIDIA card averages 36530. That difference is roughly 24% in favor of AMD, but the average masks just how dependent that margin is on the Metal result.

The Verdict

The data supports a clear split decision. Users whose workloads rely on Metal should choose the AMD Radeon Pro 5500 XT without hesitation. Its 54779 Metal score is more than triple the NVIDIA card's result, and no other benchmark in this comparison comes close to reversing that advantage. The AMD card also holds a narrow OpenCL edge, albeit a marginal one at 0.7%.

Users who prioritize Vulkan performance should pick the NVIDIA GeForce GTX TITAN X. Its 49397 Vulkan score beats the AMD card by 19.8%, and that is a substantial margin for a single API. The NVIDIA card also offers more memory, 12 GB versus 8 GB, and higher raw FP32 throughput, 6.691 TFLOPS versus 5.398 TFLOPS, which may matter in compute tasks that are not well captured by these three benchmark tests.

The overall average score favors AMD at 45384 versus 36530, and the percentile ranking also favors AMD at 84 versus 80. However, the NVIDIA card's superior Vulkan result means that API selection is the single most important factor in this decision. A Vulkan-centric application or game will perform noticeably better on the GTX TITAN X, while Metal-centric environments will overwhelmingly favor the Radeon Pro 5500 XT.

Specification Differences

The two cards differ across nearly every major specification category. The AMD Radeon Pro 5500 XT uses a Navi 14 chip built on TSMC's 7 nm process, with 6,400 million transistors on a 158 mm² die. The NVIDIA GeForce GTX TITAN X uses a GM200 chip on a 28 nm process, with 8,000 million transistors on a much larger 601 mm² die. Transistor density reflects the process gap: 40.5M per mm² for AMD versus 13.3M per mm² for NVIDIA.

Clock speeds favor AMD. The Radeon Pro 5500 XT runs at a base of 1187 MHz and boosts to 1757 MHz, while the GTX TITAN X runs at 1000 MHz base and 1089 MHz boost. Memory configurations also diverge sharply: the AMD card uses 8 GB of GDDR6 at 14 Gbps effective on a 128-bit bus, while the NVIDIA card uses 12 GB of GDDR5 at 7 Gbps effective on a 384-bit bus. The wider bus gives NVIDIA a bandwidth advantage of 336.6 GB/s versus 224.0 GB/s.

Compute unit counts differ as well. The AMD card has 1536 shading units, 96 TMUs, and 32 ROPs. The NVIDIA card has 3072 shading units, 192 TMUs, and 96 ROPs. Pixel rate and texture rate both favor NVIDIA: 104.5 GPixel/s versus 56.22 GPixel/s, and 209.1 GTexel/s versus 168.7 GTexel/s. FP32 compute also favors NVIDIA at 6.691 TFLOPS versus 5.398 TFLOPS, while the AMD card offers FP16 at 10.80 TFLOPS (2:1) and the NVIDIA card has no recorded FP16 rating.

Power and physical design are opposites. The AMD card is an IGP with no power connectors, a 125 W TDP, and a 300 W suggested PSU. The NVIDIA card is a dual-slot design measuring 267 mm in length, 111 mm in height, and 38 mm in width, with one 6-pin and one 8-pin connector, a 250 W TDP, and a 600 W suggested PSU. The AMD card has no display outputs, while the NVIDIA card offers 1x DVI, 1x HDMI 2.0, and 3x DisplayPort 1.2. The bus interface also differs: PCIe 4.0 x8 for AMD versus PCIe 3.0 x16 for NVIDIA.

Architecture Differences

The architectural gap between these two GPUs is fundamental. The AMD Radeon Pro 5500 XT is built on RDNA 1.0, a modern architecture designed for efficient instruction execution and higher clock speeds. It uses a 7 nm TSMC process, which allows a compact 158 mm² die while still packing 6,400 million transistors. The NVIDIA GeForce GTX TITAN X uses Maxwell 2.0, an older architecture from the GeForce 900 generation, fabricated on a 28 nm process with a 601 mm² die.

The transistor counts tell an interesting story. NVIDIA packs 8,000 million transistors into its large die, but the older process means a transistor density of only 13.3M per mm². AMD fits fewer transistors, 6,400 million, into a much smaller area, achieving 40.5M per mm². This density advantage is the root cause of the AMD card's lower power draw, 125 W versus 250 W, and its higher boost clock of 1757 MHz versus 1089 MHz.

The NVIDIA card compensates with raw resource counts. Its 3072 shading units, 192 TMUs, and 96 ROPs are all double or triple the AMD card's counts of 1536 shading units, 96 TMUs, and 32 ROPs. The wider 384-bit memory bus is also a Maxwell-era design choice that prioritizes bandwidth over density. The AMD card instead relies on GDDR6 memory at 14 Gbps effective to reach 224.0 GB/s from a 128-bit bus.

Feature support is similar at the API level, with both cards reporting DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. Neither card has ray tracing cores or tensor cores recorded in the database. The AMD card includes FP16 support at 10.80 TFLOPS (2:1), a feature that the NVIDIA card lacks entirely. This architectural difference may matter for workloads that leverage half-precision compute.

Where Each One Wins

The AMD Radeon Pro 5500 XT wins in Metal workloads by a staggering margin. Its 54779 Metal score versus 18723 for the NVIDIA card means any Metal-based application, typically found in macOS environments, will run dramatically better on the AMD card. The 192.6% delta is the largest in this comparison and alone justifies choosing the AMD card for Metal-centric use cases.

The AMD card also edges out the NVIDIA card in OpenCL, though the 0.7% margin is small enough to be considered a tie in practical terms. Its lower power draw, 125 W versus 250 W, and IGP form factor make it the better choice for compact or power-constrained systems, provided the user does not need display outputs, since the AMD card has none.

The NVIDIA GeForce GTX TITAN X wins in Vulkan by a solid 19.8%, making it the better option for Vulkan-based games and compute applications. Its 12 GB of memory and 336.6 GB/s bandwidth also give it an advantage in memory-heavy workloads that exceed the AMD card's 8 GB capacity. The NVIDIA card's higher FP32 throughput, 6.691 TFLOPS versus 5.398 TFLOPS, may also benefit compute tasks that rely on single-precision math.

The NVIDIA card is the only one of the two with display outputs, offering 1x DVI, 1x HDMI 2.0, and 3x DisplayPort 1.2, so it is the practical choice for direct display connection. Its dual-slot design and 600 W suggested PSU require a larger chassis and more power headroom, but that is the trade-off for its higher raw throughput and larger memory pool. In the end, the AMD card wins for modern API efficiency and Metal environments, while the NVIDIA card wins for Vulkan performance and memory capacity.
