NVIDIA CMP 50HX vs NVIDIA RTX A1000 Mobile Comparison

# The Verdict

The data presents a clear but nuanced picture. The NVIDIA CMP 50HX wins both head-to-head benchmark comparisons, taking the Geekbench OpenCL test with a 15.3% margin (56,135 vs. 48,703) and the Vulkan test with a narrower 1.4% edge (47,445 vs. 46,782). Its average benchmark score of 51,790 places it 8.5% above the RTX A1000 Mobile's 47,743, and its percentile ranking of 86 versus 85 confirms that both sit in the same performance tier overall.

However, the choice between these two is not simply a matter of raw score. The CMP 50HX is a dual-slot mining card with no display outputs, drawing 250 W and requiring two 8-pin power connectors plus a 600 W suggested PSU. The RTX A1000 Mobile is an integrated graphics processor (IGP) with a 60 W TDP, no power connectors, and display outputs described as "Portable Device Dependent." The CMP 50HX is a desktop-bound compute tool; the A1000 Mobile is a laptop component whose performance is contingent on the host system.

For users who need maximum compute throughput in a desktop chassis and do not require video output from the card itself, the CMP 50HX is the data-backed choice, particularly in OpenCL workloads where its lead is substantial. For those building or upgrading a portable workstation where power draw and physical footprint are constrained, the RTX A1000 Mobile offers 85th-percentile performance in a 60 W envelope, making it the logical selection despite its lower raw scores. The 1.4% Vulkan gap suggests that in API-specific scenarios, the two are nearly interchangeable.

Architecture Differences

The architectural divide here is generational. The CMP 50HX is built on the Turing architecture using the TU102 chip, fabricated on TSMC's 12 nm process. It packs 18,600 million transistors into a 754 mm² die, yielding a transistor density of 24.7 million per square millimeter. The RTX A1000 Mobile uses the Ampere architecture with the GA107 chip, manufactured by Samsung on an 8 nm process. Its 8,700 million transistors occupy a 200 mm² die, achieving a significantly higher density of 43.5 million per square millimeter.

These architectural choices translate directly into feature sets. The CMP 50HX carries 56 RT cores and 448 tensor cores, while the A1000 Mobile has 16 RT cores and 64 tensor cores. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The CMP 50HX offers FP16 performance of 22.15 TFLOPS via a 2:1 ratio to its 11.07 TFLOPS FP32 throughput. The A1000 Mobile's FP16 is 4.669 TFLOPS at a 1:1 ratio, meaning it offers no dedicated half-precision boost.

The memory subsystems reflect their divergent purposes. The CMP 50HX uses 10 GB of GDDR6 on a 320-bit bus, delivering 560.0 GB/s of bandwidth with an effective memory clock of 14 Gbps. The A1000 Mobile has 4 GB of GDDR6 on a 128-bit bus, achieving 176.0 GB/s with an 11 Gbps effective rate. The CMP 50HX's memory bandwidth advantage is 218% — a decisive factor for memory-bound compute workloads.

Head-to-Head Benchmarks

The Geekbench OpenCL result is the most telling data point. The CMP 50HX scores 56,135 against the A1000 Mobile's 48,703, a margin of 15.3%. This is consistent with the massive differences in shading units (3,584 vs. 2,048), texture mapping units (192 vs. 64), and raster operation units (80 vs. 32). The CMP 50HX also has a substantial clock advantage: its 1,545 MHz boost clock versus the A1000 Mobile's 1,140 MHz. The combination of 75% more shading units and a 35.5% higher boost clock explains the OpenCL gap.

The Vulkan result is far closer. The CMP 50HX leads with 47,445 against 46,782, a mere 1.4% difference. This narrowing suggests that Vulkan workloads may be more sensitive to factors other than raw compute throughput — possibly memory latency, driver optimization, or the specific shader characteristics of the test. The A1000 Mobile's 60 W power envelope and IGP form factor do not appear to handicap it severely in this API, as its score lands within 2% of the CMP 50HX.

Context from the nearest rivals reinforces these findings. The CMP 50HX's average score of 51,790 puts it 1.6% ahead of the AMD Radeon RX 6900 XT (50,951), 3.6% ahead of the RX Vega 64 (50,001), and 3.7% ahead of the GeForce RTX 5070 Ti (49,957). The A1000 Mobile's 47,743 average is 1.5% behind the Radeon RX 6800 XT (48,477) but 2.2% ahead of the RX 6550M (46,702) and 2.4% ahead of the Intel Arc A530M (46,614). These deltas show both cards competing effectively against much larger desktop parts in the case of the A1000 Mobile, and against flagship-level hardware in the case of the CMP 50HX.
