Intel Arc A770 vs NVIDIA CMP 50HX Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive victory for the Intel Arc A770 across every shared benchmark test. In Geekbench OpenCL, the Arc A770 scores 109,175 points against the CMP 50HX's 56,135 points, a lead of 94.5%. That is nearly double the compute output in a general-purpose workload that stresses raw shader throughput and memory subsystem efficiency.

The gap widens further in Geekbench Vulkan, where the Arc A770 posts 94,284 points versus 47,445 points for the CMP 50HX. The delta here reaches 98.7%, meaning the Intel part effectively doubles the NVIDIA card's performance in this API. Vulkan results often reflect driver maturity and architectural efficiency, and the data indicates Intel's Xe-HPG implementation extracts far more usable performance from its hardware in this specific test.

Looking at the broader average benchmark scores, the Arc A770 sits at 68,809 points, while the CMP 50HX averages 51,790 points. That is a 32.9% overall advantage for the Intel card when aggregating all recorded tests. The nearest rival data places the Arc A770 in a tight cluster: the NVIDIA CMP 90HX trails by only 0.3%, the AMD Radeon Instinct MI25 is 0.4% behind, the AMD Radeon Pro WX 8200 sits 1.5% lower, and the NVIDIA Quadro P6000 is 1.7% behind. This shows the Arc A770 is competitively positioned among professional and high-end workstation GPUs, not just mining-oriented hardware.

The CMP 50HX, by contrast, finds itself among a different set of peers. Its nearest rivals include the AMD Radeon RX 6900 XT, which the CMP 50HX leads by 1.6%, the AMD Radeon RX Vega 64 at 3.6% ahead, the NVIDIA GeForce RTX 5070 Ti at 3.7% ahead, and the Intel Arc A550M at 4.1% ahead. These margins are modest, indicating the CMP 50HX sits in the upper-midrange performance tier despite its mining-focused pedigree.

In the head-to-head tally, the Arc A770 wins both available comparisons: Geekbench OpenCL and Geekbench Vulkan. The CMP 50HX records zero wins. The pattern is unambiguous: whenever both cards run the same workload, the Intel part finishes with a substantial margin, often approaching or exceeding double the score.

Where Each One Wins

The Arc A770 dominates in compute-heavy, API-level benchmarks. Its Geekbench OpenCL and Vulkan scores are not just higher; they are transformative differences. For workloads that rely on OpenCL, such as certain rendering pipelines, physics simulations, or data-parallel tasks, the Arc A770 delivers 94.5% more performance than the CMP 50HX. In Vulkan-based applications, including modern game engines and cross-platform graphics APIs, the advantage expands to 98.7%. This makes the Arc A770 the clear choice for any task where these APIs are the primary execution path.

The CMP 50HX, based on the recorded data, does not win any benchmark category. Its only competitive positioning comes from its average score relative to its nearest rivals, where it edges out the RX 6900 XT, RX Vega 64, RTX 5070 Ti, and Arc A550M by slim margins ranging from 1.6% to 4.1%. However, against the Arc A770 specifically, the CMP 50HX has no redeeming benchmark victory. Its 10 GB memory capacity and 560.0 GB/s bandwidth are notable specifications, but the actual measured performance does not translate into a single winning test.

For users who prioritize raw compute in OpenCL or Vulkan, the Arc A770 is unequivocally superior. The data does not support any scenario where the CMP 50HX outperforms the Arc A770 in the recorded benchmarks. The CMP 50HX's niche appears to be narrow: it is a mining-oriented card with no display outputs, so its use case is inherently limited to compute tasks that do not require video presentation. Even within that scope, the Arc A770's benchmark scores indicate it is the faster processor.

Architecture Differences

The two cards come from different architectural lineages. The Intel Arc A770 is built on the Xe-HPG architecture, specifically the DG2-512 chip, and belongs to the Alchemist generation (Arc 7). It is fabricated on a 6 nm process at TSMC, with 21,700 million transistors packed into a 406 mm² die. That yields a transistor density of 53.4 million per mm², a figure enabled by the modern process node.

The NVIDIA CMP 50HX uses the Turing architecture with the TU102 chip, part of the Mining GPUs generation. It is built on a 12 nm process, also at TSMC, with 18,600 million transistors spread across a much larger 754 mm² die. Its transistor density is 24.7 million per mm², less than half that of the Intel chip due to the older fabrication process.

Core configurations differ significantly. The Arc A770 features 4,096 shading units, 256 texture mapping units, and 128 raster operation pipelines. It also includes 32 ray tracing cores but no dedicated tensor cores. The CMP 50HX has 3,584 shading units, 192 TMUs, and 80 ROPs, along with 56 ray tracing cores and 448 tensor cores. The NVIDIA card has more ray tracing hardware and tensor cores, but fewer of the traditional shading and texturing units.

Clock speeds favor Intel. The Arc A770 runs at a base clock of 2100 MHz and boosts to 2400 MHz. The CMP 50HX operates at a 1350 MHz base and 1545 MHz boost. The memory clocks also differ: the Arc A770 uses 2000 MHz memory (16 Gbps effective), while the CMP 50HX uses 1750 MHz (14 Gbps effective).

Memory configurations are distinct. The Arc A770 has 16 GB of GDDR6 on a 256-bit bus, delivering 512.0 GB/s of bandwidth. The CMP 50HX has 10 GB of GDDR6 on a wider 320-bit bus, achieving 560.0 GB/s. Despite having less capacity, the CMP 50HX offers higher bandwidth due to its wider memory interface.

The bus interface is a major differentiator. The Arc A770 uses PCIe 4.0 x16, a standard full-bandwidth slot. The CMP 50HX uses PCIe 1.0 x4, an extremely narrow interface that severely limits data transfer between the card and the host system. This likely contributes to the CMP 50HX's lower benchmark scores, as it cannot feed data to the GPU quickly enough.

Display capabilities also diverge. The Arc A770 has 1x HDMI 2.1 and 3x DisplayPort 2.0 outputs, making it a fully functional graphics card. The CMP 50HX has no display outputs at all, as it was designed exclusively for mining operations.

Power requirements are similar in magnitude: the Arc A770 has a TDP of 225 W and requires a 550 W power supply, while the CMP 50HX has a TDP of 250 W and needs a 600 W unit. The Arc A770 uses a 1x 6-pin plus 1x 8-pin connector setup, whereas the CMP 50HX uses 2x 8-pin connectors. Both are dual-slot cards.

Physical dimensions are only recorded for the CMP 50HX: 267 mm in length, 116 mm in height, and 35 mm in width. The Arc A770's dimensions are not listed in the database.

The Arc A770's release date is October 11, 2022, with a successor named Battlemage and a predecessor of Xe Graphics. The CMP 50HX was released June 23, 2021, with no predecessor or successor recorded. Both are end-of-life products. The Arc A770's launch MSRP is 329 USD, while no launch MSRP is recorded for the CMP 50HX.

The Verdict

The benchmark data makes the choice straightforward. The Intel Arc A770 outperforms the NVIDIA CMP 50HX in every recorded test, with margins of 94.5% in OpenCL and 98.7% in Vulkan. Its average benchmark score of 68,809 points places it in the 90th percentile of all GPUs, while the CMP 50HX's 51,790 points places it in the 86th percentile. The Arc A770 also offers 16 GB of memory, display outputs, and a modern PCIe 4.0 x16 interface, making it a far more versatile product.

The CMP 50HX's only advantages in the data are its higher memory bandwidth (560.0 GB/s versus 512.0 GB/s) and its larger number of RT cores (56 versus 32) and tensor cores (448 versus none). However, these specifications do not translate into benchmark wins. The card's PCIe 1.0 x4 interface is a severe bottleneck, and its lack of display outputs limits its utility to mining or headless compute tasks.

For any user choosing between these two based on the recorded data, the Arc A770 is the superior performer. It wins all head-to-head tests, offers more memory, and has a functional display output suite. The CMP 50HX is a specialized mining card with no display support and slower measured performance. The data does not identify any workload where the CMP 50HX would be the better pick, given that its only winning margins are against different rivals, not against the Arc A770.

The Arc A770 also has the advantage of a recorded launch MSRP of 329 USD, providing a reference point for its market positioning. The CMP 50HX has no such recorded price, making its value proposition harder to assess. Ultimately, the Arc A770 is the recommended choice for compute and graphics tasks based on benchmark evidence alone.
