AMD Radeon HD 6770 vs Intel HD Graphics 630 Comparison

Intel HD Graphics 630 and AMD Radeon HD 6770 represent two very different eras of GPU design, one an integrated solution embedded in a processor, the other a dedicated add-in board. The recorded data shows a closer contest than their release timelines might suggest, with the AMD card holding a narrow edge in the only directly comparable benchmark.

Head-to-Head Benchmarks

The database includes a single direct comparison between these two GPUs: the Geekbench OpenCL test. In that measurement, the AMD Radeon HD 6770 scores 3649, while the Intel HD Graphics 630 scores 3587. This gives AMD a 1.7 percent advantage, a margin that is nearly negligible in real-world terms. The delta is small enough that run-to-run variance on either platform could plausibly flip the result, but the recorded data clearly lists the AMD part as the winner of this head-to-head encounter.

Beyond that single direct test, the broader benchmark averages paint a similar picture. The Intel HD Graphics 630 carries an average benchmark score of 4075 across all recorded tests, which includes Geekbench Metal, OpenCL, and Vulkan results. The AMD Radeon HD 6770 has an average score of 3649, but that figure comes from only one recorded test, the OpenCL result. This discrepancy is important: the Intel part benefits from multiple benchmark submissions, including a strong Geekbench Metal score of 5099 and a Vulkan score of 3540, both of which pull its average upward. The AMD card has no Metal or Vulkan results in the database, so its average is entirely dependent on the single OpenCL measurement.

Look at the percentile rankings and the gap becomes clearer. The Intel HD Graphics 630 sits at the 24th percentile of all GPUs in the database, while the AMD Radeon HD 6770 sits at the 22nd percentile. These are adjacent positions, separated by just two percentile points, which reinforces the idea that these two products occupy a similar performance tier despite their architectural differences.

The rival comparisons in the database further contextualize each card. The Intel HD Graphics 630 is listed alongside the AMD Radeon RX 9060 XT 8 GB, which has an average score of 4093, a 0.4 percent difference from the Intel part. It also sits near the NVIDIA GeForce GT 755M at 4033, the AMD FirePro M4150 at 4013, and the NVIDIA Quadro K2100M at 4151. The Intel GPU trails the Quadro K2100M by 1.8 percent and the RX 9060 XT by 0.4 percent, while leading the GT 755M by 1 percent and the FirePro M4150 by 1.5 percent. These are all sub-2 percent deltas, meaning the Intel integrated GPU is clustered tightly with a group of modest dedicated mobile and entry-level workstation parts.

The AMD Radeon HD 6770 has its own rival set. It is compared to the NVIDIA GeForce GTX 1050 at 3629, a 0.6 percent difference, the NVIDIA GeForce GT 735M at 3616, a 0.9 percent lead for AMD, the NVIDIA GeForce 825M at 3694, a 1.2 percent deficit, and the NVIDIA RTX 5000 Mobile Ada Generation at 3596, a 1.5 percent advantage. Notice that the AMD card is grouped with a mix of older and newer low-end parts, and its deltas against them are similarly tight, all within 1.5 percent in either direction. The Intel HD Graphics 630, by contrast, is grouped with slightly faster company, which suggests the database's aggregate metrics consider the Intel part marginally more competitive in its peer set.

Where Each One Wins

The AMD Radeon HD 6770 wins the only direct head-to-head benchmark, the Geekbench OpenCL test, by 1.7 percent. That is its sole recorded victory in the database. For workloads that rely on OpenCL compute, the data indicates the AMD card holds a slight but measurable edge over the Intel HD Graphics 630.

The Intel HD Graphics 630, however, wins in overall benchmark coverage and in peak scores. Its Geekbench Metal result of 5099 is the highest single score recorded for either GPU, and no Metal result exists for the AMD card. The Intel part also records a Geekbench Vulkan score of 3540, a test the AMD Radeon HD 6770 cannot run because its API support does not include Vulkan. If the workload uses Metal or Vulkan, the Intel GPU is the only option of the two, and its Metal score in particular is substantially above its OpenCL figure.

For legacy DirectX workloads, the AMD card supports DirectX 11.2, while the Intel part supports DirectX 12 (12_1). The AMD GPU's OpenGL support reaches 4.4, while the Intel GPU reaches 4.6. Neither card supports modern ray tracing or tensor operations, as the database lists no RT or tensor core counts for either. The AMD card has no Vulkan support at all, which limits its relevance for modern cross-platform compute and graphics APIs.

The use-case split comes down to this: the AMD Radeon HD 6770 is the choice for pure OpenCL compute, where its 1.7 percent lead represents the only direct performance win in the record. The Intel HD Graphics 630 is the choice for API coverage and peak synthetic scores, with Metal and Vulkan results that the AMD card cannot match, plus a higher average benchmark score when all recorded tests are considered.

Architecture Differences

The two GPUs come from fundamentally different design philosophies. The Intel HD Graphics 630 is an integrated graphics processor built on the Kaby Lake GT2 chip, using Intel's Generation 9.5 architecture. It is fabricated on a 14 nm++ process at Intel's own foundry. The AMD Radeon HD 6770 is a dedicated discrete GPU based on the Juniper chip, using AMD's TeraScale 2 architecture, and it is fabricated on a 40 nm process at TSMC.

The process node gap is significant. The Intel part's 14 nm++ process is much more advanced than the 40 nm node used for the AMD card, which explains how the integrated GPU can deliver competitive compute results while consuming far less power. The AMD Radeon HD 6770 has a thermal design power of 108 W and requires a dual-slot cooler with a single 6-pin power connector and a suggested power supply of 300 W. The Intel HD Graphics 630 has a TDP of just 15 W and is an IGP, meaning it draws power from the host processor's platform and requires no separate cooler or power connectors.

The transistor counts and die sizes reflect the different design goals. The AMD Juniper chip contains 1,040 million transistors on a 166 mm² die, with a transistor density of 6.3 million per square millimeter. The Intel Kaby Lake GT2 chip does not have transistor or die size data in the database, but its 14 nm++ process and integrated nature imply a very different physical implementation.

Compute resources differ substantially. The AMD Radeon HD 6770 has 800 shading units, 40 texture mapping units, and 16 raster output units. The Intel HD Graphics 630 has 192 shading units, 24 TMUs, and only 3 ROPs. Despite having far fewer shading units, the Intel part achieves competitive OpenCL scores because of its higher architectural efficiency per unit, a common trait of newer GPU designs.

Raw throughput numbers show the AMD card's advantage in traditional fill-rate metrics. The AMD Radeon HD 6770 reaches a pixel rate of 13.60 GPixel/s and a texture rate of 34.00 GTexel/s, while the Intel HD Graphics 630 manages 3.000 GPixel/s and 24.00 GTexel/s. In FP32 compute, the AMD card delivers 1,360.0 GFLOPS, while the Intel part delivers 384.0 GFLOPS. The Intel GPU does have a FP16 rate of 768.0 GFLOPS, which is double its FP32 rate, but the AMD card has no recorded FP16 capability.

Memory systems are entirely different. The AMD Radeon HD 6770 uses 1024 MB of dedicated GDDR5 memory on a 128-bit bus, with a bandwidth of 76.80 GB/s. The Intel HD Graphics 630 uses system shared memory, with a bus width and bandwidth that are system dependent. The AMD card's memory clock runs at 1200 MHz with 4.8 Gbps effective data rate, while the Intel part's memory clock is simply listed as system shared.

The AMD card connects via PCIe 2.0 x16 and is a dual-slot card measuring 198 mm in length. The Intel part uses a ring bus interface and is motherboard dependent for its display outputs. The AMD card offers 2x DVI, 1x HDMI 1.3a, and 2x mini-DisplayPort 1.1 outputs, while the Intel GPU's display outputs depend entirely on the host motherboard.

Release dates and successors further separate the two. The AMD Radeon HD 6770 was released on January 20, 2011, with a predecessor in the Evergreen family and a successor in Southern Islands. The Intel HD Graphics 630 was released on August 29, 2016, as part of the Kaby Lake generation. Both are now listed as end-of-life products.

The Verdict

The data presents a nuanced picture. In the only directly comparable benchmark, the AMD Radeon HD 6770 wins by 1.7 percent in Geekbench OpenCL. That is a real but small margin, and it comes from a GPU with 800 shading units, 40 TMUs, and 16 ROPs, backed by 1024 MB of dedicated GDDR5 memory and 76.80 GB/s of bandwidth. The Intel HD Graphics 630 counters with 192 shading units, 24 TMUs, 3 ROPs, and shared system memory, yet it still scores within 1.7 percent of the AMD card in OpenCL.

The Intel part takes the overall average benchmark crown at 4075 versus 3649, though that comparison is skewed by the Intel GPU's three recorded tests versus the AMD card's one. The Intel GPU also offers Metal and Vulkan support, with a Metal score of 5099 that nothing on the AMD side can approach.

For a buyer or system builder choosing between these two, the decision rests on the workload. If the task is OpenCL compute on a legacy platform, the AMD Radeon HD 6770 is the safer pick, its 1.7 percent lead in the direct test is the only head-to-head win in the record. If the task involves modern APIs, lower power consumption, or integrated simplicity, the Intel HD Graphics 630 is the clear choice, its 15 W TDP, Vulkan support, and Metal performance are metrics the AMD card cannot match, and its average benchmark score is higher overall.

Both products are end-of-life, and both sit near the bottom of the database's percentile rankings, at 24 for Intel and 22 for AMD. Neither is a performance part by modern standards. The AMD Radeon HD 6770 is a dedicated card from the TeraScale 2 era with a 108 W power draw and a 300 W power supply recommendation, while the Intel HD Graphics 630 is a low-power integrated solution from the Kaby Lake generation. The recorded data suggests they are near equals in raw OpenCL throughput, with the AMD card holding a narrow edge, while the Intel part offers broader API support and a higher peak score in Metal. Choose the AMD card for the slight OpenCL win, choose the Intel GPU for everything else the database measures.
