AMD Radeon Pro Vega II vs NVIDIA TITAN X Pascal Comparison

Head-to-Head Benchmarks

The benchmark database records two direct comparisons between the AMD Radeon Pro Vega II and the NVIDIA TITAN X Pascal, and in both instances the AMD card takes a decisive lead. Starting with the Geekbench OpenCL test, the Radeon Pro Vega II scores 99,048 against the TITAN X Pascal's 66,696. That is a 48.5% advantage, a substantial margin that reflects the AMD card's higher compute throughput in general-purpose workloads. The OpenCL result is particularly telling because it stresses raw shader and memory performance rather than game-specific optimizations.

In the Vulkan API test, the gap narrows but remains firmly in AMD's favor. The Radeon Pro Vega II posts 99,621, while the TITAN X Pascal manages 77,499. The delta here is 28.5%, still a commanding lead but notably smaller than the OpenCL spread. This suggests that Vulkan workloads, which often exercise driver efficiency and command overhead, bring the NVIDIA card relatively closer, yet the AMD card still holds a clear edge in both recorded metrics.

The aggregate benchmark picture reinforces the same story. The Radeon Pro Vega II holds an average benchmark score of 109,617 across all recorded tests, placing it in the 94th percentile among all GPUs in the database. The TITAN X Pascal averages 72,098, which puts it in the 91st percentile. While both cards sit in the top decile of performance, the AMD part sits roughly 52% higher in average score, a difference that corresponds to its two direct test victories. The head-to-head record stands at 2 wins for the Radeon Pro Vega II and 0 wins for the TITAN X Pascal.

Looking at the rival context, the Radeon Pro Vega II's nearest competitors in the database include the AMD Radeon PRO W7900 at 110,725 average score, which is 1% ahead, and the AMD Radeon Pro W6600X at 107,342, which the Vega II beats by 2.1%. The NVIDIA RTX A5500 Mobile at 113,944 sits 3.8% ahead. The TITAN X Pascal, by contrast, is bracketed by AMD parts: the Radeon Vega Frontier Edition is 1.7% ahead, the Radeon Pro Vega 64 is 0.4% behind, and the Radeon RX 6650M trails by 0.5%. This positioning shows that the TITAN X Pascal competes with older Vega-era AMD workstation parts, while the Radeon Pro Vega II sits in a higher performance tier altogether.

The Verdict

The data points to a clear winner for compute-oriented users. The AMD Radeon Pro Vega II outperforms the NVIDIA TITAN X Pascal in every recorded benchmark, with margins of 48.5% in OpenCL and 28.5% in Vulkan. Its average benchmark score of 109,617 versus 72,098 places it in a different performance class, and its 94th percentile standing versus the TITAN's 91st confirms that gap in percentile terms.

Who should pick the AMD Radeon Pro Vega II? Users whose workloads depend on OpenCL compute, high-bandwidth memory, or large framebuffers. The card offers 32 GB of HBM2 memory with a 4096-bit bus and 825.3 GB/s bandwidth, which is more than double the TITAN X Pascal's 480.4 GB/s. For professional rendering, machine learning inference, or data-parallel tasks that scale with memory bandwidth, the Vega II is the obvious choice from this comparison.

Who should pick the NVIDIA TITAN X Pascal? Users who need a dual-slot card with modest power requirements. The TITAN X Pascal draws 250 W and fits in a dual-slot form factor, whereas the Radeon Pro Vega II is a quad-slot card with a 475 W TDP and an 850 W suggested PSU. The NVIDIA card also offers a higher pixel rate at 147.0 GPixel/s versus 110.1 GPixel/s, which could benefit certain rasterization-heavy tasks. Additionally, the TITAN X Pascal supports Vulkan 1.4 in the database, while the Vega II lists Vulkan 1.3. For users constrained by chassis space or power delivery, the TITAN X Pascal remains a viable option, but purely on benchmark performance, it loses ground in every recorded test.

The verdict from the recorded data is unambiguous: the Radeon Pro Vega II is the faster card by a wide margin, and the TITAN X Pascal's advantages are limited to physical dimensions, power draw, and a slightly newer Vulkan revision.

Specification Differences

The two cards diverge significantly across nearly every hardware specification. The AMD Radeon Pro Vega II features 4096 shading units and 256 texture mapping units, while the NVIDIA TITAN X Pascal has 3584 shading units and 224 TMUs. In terms of render output units, the TITAN X Pascal has more at 96 versus the Vega II's 64. Clock speeds show the Vega II running at a 1574 MHz base and 1720 MHz boost, while the TITAN X Pascal operates at 1417 MHz base and 1531 MHz boost.

Memory capacity heavily favors the AMD card: 32 GB of HBM2 with a 4096-bit bus and 825.3 GB/s bandwidth versus 12 GB of GDDR5X with a 384-bit bus and 480.4 GB/s bandwidth. The memory clock also differs, with the Vega II at 806 MHz (1612 Mbps effective) and the TITAN X Pascal at 1251 MHz (10 Gbps effective).

Compute throughput shows the Vega II at 14.09 TFLOPS FP32 and 28.18 TFLOPS FP16 (2:1), while the TITAN X Pascal delivers 10.97 TFLOPS FP32 and only 171.5 GFLOPS FP16 (1:64). Pixel and texture rates also differ: the Vega II posts 110.1 GPixel/s and 440.3 GTexel/s, while the TITAN X Pascal posts 147.0 GPixel/s and 342.9 GTexel/s.

Physical and power characteristics are starkly different. The Radeon Pro Vega II is a quad-slot card with a 475 W TDP and an 850 W suggested PSU, while the TITAN X Pascal is a dual-slot card with a 250 W TDP and a 600 W suggested PSU. The TITAN X Pascal uses a PCIe 3.0 x16 interface and requires a 1x 6-pin plus 1x 8-pin power connector, whereas the Vega II uses the Apple MPX bus interface with no listed power connectors. The TITAN X Pascal measures 267 mm in length, 112 mm in height, and 40 mm in width; the Vega II has no recorded dimensions.

Display outputs differ as well: the Vega II offers 1x HDMI 2.0b and 4x Thunderbolt, while the TITAN X Pascal provides 1x DVI, 1x HDMI 2.0, and 3x DisplayPort 1.4a. The TITAN X Pascal lists Vulkan 1.4 support, while the Vega II lists Vulkan 1.3; both support DirectX 12 (12_1) and OpenGL 4.6.

Architecture Differences

The AMD Radeon Pro Vega II is built on the Vega 20 chip using the GCN 5.1 architecture, manufactured on a 7 nm process at TSMC. It contains 13,230 million transistors on a 331 mm² die, yielding a transistor density of 40.0 million per mm². The NVIDIA TITAN X Pascal uses the GP102 chip with the Pascal architecture, built on a 16 nm process, also at TSMC. It packs 11,800 million transistors on a larger 471 mm² die, resulting in a lower transistor density of 25.1 million per mm².

The process node difference is significant: 7 nm versus 16 nm. This explains why the Vega II achieves higher transistor density despite having more transistors on a smaller die. The Vega II belongs to the Radeon Pro Mac (Vega Series) generation and was released on 2019-06-02, while the TITAN X Pascal belongs to the GeForce 10 generation and was released on 2016-08-01.

In terms of compute features, the Vega II offers FP16 throughput at a 2:1 ratio relative to FP32, reaching 28.18 TFLOPS, whereas the TITAN X Pascal provides FP16 at a 1:64 ratio, delivering only 171.5 GFLOPS. This makes the Vega II dramatically more capable in half-precision workloads, which matters for machine learning training and certain scientific computations.

Neither card includes dedicated ray tracing cores or tensor cores, as those fields are null for both. The Vega II uses HBM2 memory with a 4096-bit interface, which is a stacked memory design, while the TITAN X Pascal uses GDDR5X on a 384-bit bus. The Vega II's memory bandwidth advantage comes from the wider bus and HBM2 technology.

The TITAN X Pascal lists a predecessor in the GeForce 900 series and a successor in the GeForce 20 series, while the Vega II has no recorded predecessor or successor. Both cards are marked as end-of-life in production status. The launch MSRP for the Vega II was 2,199 USD, and for the TITAN X Pascal it was 1,199 USD, though pricing considerations are separate from architectural merit.

The architectural gap is generational: Vega 20 on 7 nm represents a newer design point than GP102 on 16 nm, and the recorded benchmarks confirm that the newer architecture translates into substantially higher compute throughput, particularly in OpenCL and Vulkan workloads.
