GPU Comparison

The Intel Arc Pro B60 and AMD Radeon HD 6770 represent two extremes of the GPU timeline, separated by over fourteen years of architectural evolution. The data shows a direct comparison that is less about competition and more about the generational chasm between a modern professional accelerator and a legacy entry-level part. While both cards occupy similar percentile ranks in the global database, the Arc Pro B60 at the 20th percentile and the HD 6770 at the 22nd, their performance profiles and intended use cases share almost no common ground.

Head-to-Head Benchmarks

The benchmark data reveals a stark disparity in available test results. The Intel Arc Pro B60 was evaluated across eight distinct workloads, including modern DirectX 12, DirectX 11, DirectX 10, DirectX 9, and compute tests. Conversely, the AMD Radeon HD 6770 has only a single recorded benchmark score: a Geekbench OpenCL result of 3649. This absence of overlapping test data makes a direct apples-to-apples comparison impossible, but the available numbers still paint a clear picture.

In the Geekbench OpenCL compute test, the AMD Radeon HD 6770 scores 3649, placing it 0.6% ahead of the NVIDIA GeForce GTX 1050 and 0.9% ahead of the NVIDIA GeForce GT 735M. The Intel Arc Pro B60, however, was not subjected to this same OpenCL test. Instead, its compute capabilities are quantified by the Passmark GPU Compute score of 7029, which is a separate metric. This compute score indicates the Arc Pro B60 delivers roughly twice the raw compute throughput of the HD 6770's single OpenCL result, though the differing test methodologies prevent a precise percentage comparison.

The Arc Pro B60’s 3DMark Steel Nomad DX12 score of 2646 demonstrates its capability in modern, API-heavy workloads. In contrast, the HD 6770 has no corresponding 3DMark result, as its DirectX 11.2 (11_0) API support and TeraScale 2 architecture predate the Steel Nomad benchmark entirely. The Passmark suite provides the only cross-generational glimpse: the Arc Pro B60 achieves a G3D score of 14580, while the HD 6770’s absence from this test list suggests it was either not run or failed to register. Looking at the Arc Pro B60’s own Passmark breakdown, DirectX 9 score of 179, DirectX 10 score of 61, DirectX 11 score of 122, and DirectX 12 score of 76, it is evident that the card’s strength lies in synthetic throughput rather than legacy API rasterization, where its modern architecture is underutilized.

The average benchmark scores further illustrate the divide. The Intel Arc Pro B60 has an average score of 3182, positioning it 0.6% above the NVIDIA Quadro P1000 and 3.5% above the NVIDIA GeForce RTX 5080 SUPER. The AMD Radeon HD 6770, with its single score, averages 3649, landing 1.5% above the NVIDIA RTX 5000 Mobile Ada Generation. Despite the HD 6770 having a higher average score, this is a statistical artifact of having only one data point; the Arc Pro B60’s multi-test average is pulled down by its weak legacy DirectX 10 and 12 Passmark scores, which are not representative of its peak capabilities.

Where Each One Wins

The Intel Arc Pro B60 wins decisively in raw compute and modern graphics workloads. Its Passmark GPU Compute score of 7029 dwarfs the HD 6770’s OpenCL result of 3649, indicating superior throughput for tasks like rendering, simulation, and data processing. In the 3DMark Steel Nomad DX12 benchmark, the Arc Pro B60’s score of 2646 showcases its ability to handle contemporary game engines and graphics APIs. Its memory subsystem, 24 GB of GDDR6 on a 192-bit bus delivering 456.0 GB/s, provides a massive bandwidth advantage over the HD 6770’s 1024 MB of GDDR5 on a 128-bit bus at 76.80 GB/s, making it the clear winner for high-resolution textures and large datasets.

The AMD Radeon HD 6770 wins in the narrow category of legacy compatibility and efficiency per watt in its specific era. Its single OpenCL score of 3649, while lower than the Arc Pro B60’s compute score, was achieved with a 108 W TDP compared to the Arc Pro B60’s 200 W TDP. The HD 6770’s 40 nm process and TeraScale 2 architecture were designed for the DirectX 11 generation, and its support for DirectX 11.2 (11_0) aligns with software from that period. For users running legacy applications that rely on older graphics drivers and APIs, the HD 6770 may offer a more stable experience, though its 800 shading units and 16 ROPs are severely outmatched by the Arc Pro B60’s 2560 shading units and 80 ROPs.

In practical terms, the Arc Pro B60 is the winner for any modern professional or gaming workload. The HD 6770’s sole victory is in its lower power draw and its status as a functioning relic for retro computing. The Arc Pro B60’s pixel rate of 192.0 GPixel/s and texture rate of 384.0 GTexel/s are orders of magnitude higher than the HD 6770’s 13.60 GPixel/s and 34.00 GTexel/s, meaning the newer card can fill frames and apply textures at speeds the older card cannot approach.

FAQ

Specification Differences

The two cards differ significantly across every core specification. The Intel Arc Pro B60 has 2560 shading units, 160 texture mapping units, and 80 render output units. The AMD Radeon HD 6770 is equipped with 800 shading units, 40 TMUs, and 16 ROPs. The Arc Pro B60’s pixel rate is 192.0 GPixel/s compared to the HD 6770’s 13.60 GPixel/s, and its texture rate is 384.0 GTexel/s versus 34.00 GTexel/s.

In terms of compute, the Arc Pro B60 delivers 12.29 TFLOPS of FP32 performance and 24.58 TFLOPS of FP16 with a 2:1 ratio. The HD 6770 offers 1,360.0 GFLOPS of FP32 and has no listed FP16 capability. The Arc Pro B60’s clock speeds are 2000 MHz base and 2400 MHz boost, while the HD 6770 has no base or boost clock listed; its memory clock is 1200 MHz (4.8 Gbps effective), compared to the Arc Pro B60’s 2375 MHz (19 Gbps effective).

The memory configuration is another major differentiator: the Arc Pro B60 has 24 GB of GDDR6 with a 192-bit bus, while the HD 6770 has 1024 MB of GDDR5 with a 128-bit bus. Power requirements also diverge, with the Arc Pro B60 rated at 200 W TDP and requiring a 550 W PSU with a 1x 8-pin connector, while the HD 6770 is rated at 108 W TDP and needs a 300 W PSU with a 1x 6-pin connector. The bus interface differs as well: the Arc Pro B60 uses PCIe 5.0 x8, and the HD 6770 uses PCIe 2.0 x16.

Display outputs are another point of divergence. The Intel Arc Pro B60 offers 4x mini-DisplayPort 2.1, while the AMD Radeon HD 6770 provides 2x DVI, 1x HDMI 1.3a, and 2x mini-DisplayPort 1.1. Physical dimensions also vary: the Arc Pro B60 measures 167 mm in length, 69 mm in height, and 40 mm in width, while the HD 6770 is 198 mm long with no listed height or width. The launch MSRP for the Arc Pro B60 is 499 USD, and for the HD 6770 it is 129 USD.

Architecture Differences

The architectural gap between these two GPUs is immense. The Intel Arc Pro B60 is built on the Xe2-HPG architecture, part of the Battlemage (Pro Series) generation, fabricated on a 5 nm process at TSMC. It contains 19,600 million transistors on a die size of 272 mm², resulting in a transistor density of 72.1M per mm². The AMD Radeon HD 6770 uses the TeraScale 2 architecture, part of the Northern Islands (HD 6700) generation, fabricated on a 40 nm process at TSMC. It contains 1,040 million transistors on a die size of 166 mm², with a transistor density of 6.3M per mm².

The Arc Pro B60’s Xe2-HPG architecture includes 20 dedicated ray tracing cores, a feature entirely absent from the HD 6770. The newer card also supports PCIe 5.0 and modern APIs including DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The HD 6770 supports DirectX 11.2 (11_0) and OpenGL 4.4, with no Vulkan support listed. The Arc Pro B60’s FP16 capability (24.58 TFLOPS) is a clear sign of its modern compute design, while the HD 6770 has no FP16 support.

The release timeline is also telling: the Arc Pro B60 was released on 2025-09-04, while the HD 6770 dates from 2011-01-20. The HD 6770’s predecessor is listed as Evergreen and its successor as Southern Islands, showing its place in the AMD product lineage. The Arc Pro B60 has no predecessor or successor listed, indicating it is a standalone current-generation product. The transistor count difference, 19,600 million versus 1,040 million, represents nearly a 19-fold increase, highlighting the density improvements of the 5 nm node over the 40 nm node. This architectural evolution translates directly into the performance and feature set advantages observed in the benchmark data.
