AMD Radeon Pro Duo vs NVIDIA RTX A1000 Mobile Comparison

Head-to-Head Benchmarks

The only direct benchmark comparison recorded in the database is Geekbench OpenCL, and the result is decisive. The NVIDIA RTX A1000 Mobile scores 48,703, while the AMD Radeon Pro Duo scores 35,860. That is a 35.8% advantage for the NVIDIA part, a substantial gap that places the two cards in different performance tiers despite both carrying professional workstation branding.

Context matters here. The RTX A1000 Mobile sits at the 85th percentile of all GPUs in the database, with an average benchmark score of 47,743. Its nearest rivals include the AMD Radeon RX 6800 XT at 48,477 (just 1.5% higher), the AMD Radeon RX 6550M at 46,702 (2.2% lower), the Intel Arc A530M at 46,614 (2.4% lower), and the AMD Radeon RX 5600M at 46,601 (2.5% lower). This places the mobile NVIDIA card in the company of desktop-class and upper-midrange mobile parts, which is remarkable given its 60 W power envelope.

The Radeon Pro Duo, meanwhile, sits at the 80th percentile with an average score of 35,860. Its nearest rivals paint a different picture: the NVIDIA Quadro GV100 scores 35,520 (1% lower), the NVIDIA GeForce RTX 5070 Ti Mobile scores 35,435 (1.2% lower), the NVIDIA T1000 scores 36,289 (1.2% higher), and the AMD Radeon RX 5300M scores 36,529 (1.8% higher). These are much older or lower-tier parts, and the Pro Duo is essentially trading blows with them. The 35.8% OpenCL gap between the two cards in this comparison is far larger than any delta between either card and its own nearest rivals, which underscores how wide the performance chasm really is.

Only one benchmark test is shared between the two cards, so the head-to-head record is clean: one win for NVIDIA, zero for AMD. The Radeon Pro Duo has no recorded Geekbench Vulkan score, so no additional comparison is possible from the database. The OpenCL result alone, however, is sufficient to establish the ordering.

Where Each One Wins

The NVIDIA RTX A1000 Mobile wins the only directly comparable workload, OpenCL compute, with a 35.8% margin. That is not a narrow victory; it is a generational leap. The data also shows Vulkan support: the RTX A1000 Mobile records a Geekbench Vulkan score of 46,782, a figure that is nearly as high as its OpenCL result. This indicates that the card maintains its compute throughput across both major API families, which matters for applications that can dispatch work through either path.

The AMD Radeon Pro Duo has no Vulkan score in the database, so its behavior under that API cannot be quantified here. Its OpenCL result of 35,860 is the only measurement recorded. Given that the Pro Duo's nearest rivals cluster within roughly 2% of that figure, the card appears to be a solid performer for its era, but the era is clearly the limiting factor.

In terms of use cases, the RTX A1000 Mobile is the pick for anyone running OpenCL-heavy workloads such as GPU compute, rendering, or scientific simulation where the API is the bottleneck. Its Vulkan score suggests it also handles modern graphics APIs comfortably. The Radeon Pro Duo, by contrast, offers no workload where the recorded data shows it ahead. Its strengths lie elsewhere, namely in memory bandwidth and raw shading resources, though those do not translate into a benchmark win in the recorded tests.

Architecture Differences

The two cards come from completely different architectural generations. The NVIDIA RTX A1000 Mobile uses the GA107 chip built on Ampere architecture, manufactured by Samsung on an 8 nm process. The die measures 200 mm² and packs 8,700 million transistors, which works out to a transistor density of 43.5 million per square millimeter. The AMD Radeon Pro Duo uses the Capsaicin chip based on GCN 3.0 architecture, built by TSMC on a 28 nm process. Its die is far larger at 596 mm², and while it contains slightly more transistors at 8,900 million, the density drops to just 14.9 million per square millimeter. That density difference is the story of process technology: the NVIDIA part crams more than twice as many transistors into roughly one third of the silicon area.

The compute resources tell a similar tale of two philosophies. The RTX A1000 Mobile has 2,048 shading units, 64 texture mapping units, and 32 ROPs. It also includes 16 ray tracing cores and 64 tensor cores, features that simply do not exist on the GCN 3.0 part. The Radeon Pro Duo counters with 4,096 shading units, 256 TMUs, and 64 ROPs, meaning it has double the raw shader count and quadruple the texture units. Its FP32 throughput is 8.192 TFLOPS, which is 75.5% higher than the RTX A1000 Mobile's 4.669 TFLOPS. FP16 performance is identical to FP32 on both cards at a 1:1 ratio, so the Pro Duo also leads in half-precision compute on paper.

The memory subsystems are radically different. The RTX A1000 Mobile uses 4 GB of GDDR6 on a 128-bit bus, delivering 176.0 GB/s of bandwidth. The Radeon Pro Duo also has 4 GB, but it is HBM on a 4096-bit bus, delivering 512.0 GB/s. That is nearly three times the bandwidth of the NVIDIA card. The Pro Duo's memory clock is listed at 500 MHz with 1000 Mbps effective, while the RTX A1000 Mobile runs its memory at 1375 MHz with 11 Gbps effective. The width of the HBM bus compensates for the lower clock, which is why the AMD card achieves such a high bandwidth figure.

Pixel and texture rates follow the raw resource counts. The Pro Duo outputs 64.00 GPixel/s and 256.0 GTexel/s, versus 36.48 GPixel/s and 72.96 GTexel/s for the RTX A1000 Mobile. The NVIDIA card's clock speeds are recorded as 630 MHz base and 1140 MHz boost, while the Radeon Pro Duo has no recorded base or boost clocks in the database, so a direct frequency comparison is not possible.

API support differs as well. The RTX A1000 Mobile supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The Radeon Pro Duo supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.2.170. The DirectX feature level gap, 12_2 versus 12_0, is significant for modern games and applications that rely on mesh shaders, variable rate shading, and other DirectX 12 Ultimate features.

Physical and power characteristics diverge sharply. The RTX A1000 Mobile is an integrated graphics package (IGP) with a 60 W TDP, no power connectors, and display outputs described as portable device dependent. The Radeon Pro Duo is a dual-slot card measuring 277 mm in length and 111 mm in height, with a 350 W TDP, three 8-pin power connectors, and a recommended 750 W power supply. It also has fixed display outputs: one HDMI 1.4a and three DisplayPort 1.2. The bus interfaces differ too: PCIe 4.0 x8 for the NVIDIA part versus PCIe 3.0 x16 for the AMD part.

The Verdict

The data points to a clear choice for most buyers. The NVIDIA RTX A1000 Mobile wins the only shared benchmark by 35.8%, and it does so while consuming 60 W versus the Radeon Pro Duo's 350 W. It also supports newer APIs, includes ray tracing and tensor cores, and comes from a far more modern process node. The Radeon Pro Duo's advantages in raw FP32 throughput and memory bandwidth do not translate into a win in the recorded OpenCL test, which is the only metric where both cards were measured.

For anyone running OpenCL compute workloads, the RTX A1000 Mobile is the faster card, period. Its 85th percentile standing among all GPUs, combined with nearest rivals that include the desktop RX 6800 XT, shows that it punches far above its power class. The Radeon Pro Duo, at the 80th percentile, is competitive with much older parts like the Quadro GV100 and T1000, but it cannot match the modern NVIDIA offering.

The Radeon Pro Duo does have a niche. Its 512.0 GB/s of memory bandwidth and 8.192 TFLOPS of FP32 compute could theoretically benefit workloads that are bandwidth-bound or that fully utilize massive parallel throughput, and its 4 GB HBM frame buffer is identical in capacity to the NVIDIA card. But the recorded benchmark does not support the idea that these theoretical advantages matter in practice, at least for OpenCL.

The production status is end-of-life for both cards. The RTX A1000 Mobile launched in late March 2022 and has a successor in the Ada-MW generation. The Radeon Pro Duo launched in late April 2016 and was succeeded by Radeon Pro Polaris. The NVIDIA card is six years newer, and the benchmark data reflects that gap.
