AMD Radeon HD 6770 vs Intel Iris Pro Graphics 5200 Comparison

Head-to-Head Benchmarks

The recorded data contains a single direct comparison between the Intel Iris Pro Graphics 5200 and the AMD Radeon HD 6770: the Geekbench OpenCL test. In this benchmark, the Intel Iris Pro Graphics 5200 scores 5,042 points, while the AMD Radeon HD 6770 scores 3,649 points. The Intel part emerges as the clear winner with a 38.2% advantage, a substantial margin that places it firmly ahead in raw compute performance as measured by this workload.

The 38.2% delta is significant. For context, the Intel Iris Pro Graphics 5200 sits at the 26th percentile of all GPUs in the database, while the AMD Radeon HD 6770 sits at the 22nd percentile. The gap between these percentiles reflects the score differential, but the delta is more striking than the percentile positions suggest. A 38.2% lead in OpenCL compute is not a marginal edge; it indicates a fundamentally different performance tier. The Intel part's average benchmark score of 4,360 points, derived from its two recorded tests, further reinforces its standing above the AMD part's 3,649 average.

Looking at the nearest rivals for each product provides additional context. The Intel Iris Pro Graphics 5200's average score of 4,360 places it within 0.6% of the NVIDIA GeForce RTX 4070 GDDR6 (4,335 points), 0.6% behind the NVIDIA GeForce 930M (4,388 points), 1.2% behind the NVIDIA GeForce GT 645M (4,411 points), and 1.5% ahead of the AMD FirePro W2100 (4,295 points). These are tight margins, showing that the Iris Pro 5200 competes in a dense cluster of similar-performing hardware.

The AMD Radeon HD 6770's average score of 3,649 places it 0.6% ahead of the NVIDIA GeForce GTX 1050 (3,629 points), 0.9% ahead of the NVIDIA GeForce GT 735M (3,616 points), 1.2% behind the NVIDIA GeForce 825M (3,694 points), and 1.5% ahead of the NVIDIA RTX 5000 Mobile Ada Generation (3,596 points). The AMD part's closest competition is similarly tight, but its overall position is lower than the Intel part's.

The head-to-head result is one-sided. The Intel Iris Pro Graphics 5200 wins the only direct benchmark recorded, with no tests where the AMD Radeon HD 6770 comes out ahead. This is a clean sweep in the available data, though it is worth remembering the comparison covers only OpenCL compute performance. The database records a single Geekbench OpenCL test for the AMD part and two tests for the Intel part (OpenCL and Vulkan). The Intel part's Vulkan score of 3,677 points is notably lower than its OpenCL score, but since no Vulkan result exists for the AMD part, a direct comparison on that API cannot be made.

The Verdict

The data points to the Intel Iris Pro Graphics 5200 as the stronger performer in compute-oriented workloads. Its Geekbench OpenCL score of 5,042 is 38.2% higher than the AMD Radeon HD 6770's 3,649, and its average benchmark score of 4,360 exceeds the AMD part's 3,649 by a wide margin. The Intel part also holds a higher percentile ranking, 26th versus 22nd, confirming its superior position in the overall distribution of GPU performance.

For users whose priority is OpenCL compute performance, the Intel Iris Pro Graphics 5200 is the clear choice. The data shows no scenario in the recorded benchmarks where the AMD Radeon HD 6770 wins. The AMD part does have advantages in other areas, such as dedicated memory and higher pixel throughput, but those are not reflected in the benchmark scores recorded in the database.

The AMD Radeon HD 6770 is an older design with a 40 nm process node and TeraScale 2 architecture. Its 108 W TDP is more than double the Intel part's 45 W, and it requires a 300 W suggested power supply plus a 6-pin power connector. The Intel Iris Pro Graphics 5200, being an integrated graphics processor, draws far less power and needs no additional connectors. For systems where power consumption and thermal output matter, the Intel part is clearly the more efficient option.

The Intel part's release date of June 2013 comes after the AMD part's January 2011 launch. Both are end-of-life products. The AMD part had a launch MSRP of 129 USD, while the Intel part has no recorded launch MSRP, as it was an integrated solution not sold as a standalone card.

Where Each One Wins

The Intel Iris Pro Graphics 5200 wins the only head-to-head benchmark recorded, the Geekbench OpenCL test, with a 38.2% margin. This makes it the better choice for compute-heavy applications that leverage OpenCL, such as general-purpose GPU tasks, video encoding, or physics simulations. Its higher FP32 performance of 736.0 GFLOPS, compared to the AMD part's 1,360.0 GFLOPS, is actually lower on paper, yet the Intel part scores higher in the OpenCL test. This suggests that the benchmark rewards other factors, such as driver optimization or architecture efficiency, beyond raw floating-point throughput.

The AMD Radeon HD 6770 does have strengths in the recorded specifications, even if they do not translate to benchmark wins. Its pixel rate of 13.60 GPixel/s is nearly three times the Intel part's 4.600 GPixel/s. Its 16 ROPs versus the Intel part's 4 ROPs gives it a structural advantage in fill-rate-bound scenarios, which can matter in traditional rasterization workloads. The AMD part also has a dedicated 1024 MB GDDR5 memory with a 128-bit bus and 76.80 GB/s bandwidth, while the Intel part relies on system-shared memory with bandwidth described as system dependent. For games or applications that are sensitive to memory bandwidth and latency, the AMD part's dedicated VRAM could offer advantages that the OpenCL benchmark does not capture.

The AMD part also has a higher texture rate in terms of raw operations, though the numbers tell a nuanced story. The Intel part's texture rate is 46.00 GTexel/s, while the AMD part's is 34.00 GTexel/s. Despite having the same number of texture mapping units (40 each), the Intel part's higher clock speed of 1150 MHz boost versus the AMD part's memory clock of 1200 MHz (with no recorded core clock) gives it an edge in texture throughput.

The AMD Radeon HD 6770 supports more display outputs, including 2x DVI, 1x HDMI 1.3a, and 2x mini-DisplayPort 1.1, while the Intel part's outputs are motherboard dependent. For multi-monitor setups or systems requiring specific display connections, the AMD part offers more flexibility out of the box.

Architecture Differences

The Intel Iris Pro Graphics 5200 is built on Intel's Haswell GT3e chip using the Generation 7.5 architecture and a 22 nm process node manufactured by Intel. It belongs to the HD Graphics (Haswell) generation. The AMD Radeon HD 6770 is built on AMD's Juniper chip using the TeraScale 2 architecture and a 40 nm process node manufactured by TSMC. It belongs to the Northern Islands (HD 6700) generation.

The process node difference is notable: the Intel part's 22 nm process is significantly more advanced than the AMD part's 40 nm process. This helps explain the Intel part's much lower TDP of 45 W versus the AMD part's 108 W, despite the Intel part having a lower transistor count (the AMD part has 1,040 million transistors on a 166 mm² die with a density of 6.3M per mm², while the Intel part's transistor count is not recorded).

The memory architectures are fundamentally different. The Intel Iris Pro Graphics 5200 uses system-shared memory with no dedicated VRAM, relying on the host system's RAM. Its memory clock is listed as system shared, and its bandwidth is system dependent. The AMD Radeon HD 6770 has dedicated 1024 MB of GDDR5 memory clocked at 1200 MHz (4.8 Gbps effective) on a 128-bit bus, providing 76.80 GB/s of bandwidth. This dedicated memory gives the AMD part a structural advantage in memory-bound workloads, though the OpenCL benchmark does not reflect this.

The compute architectures also differ substantially. The Intel part has 320 shading units, 40 texture mapping units, and 4 ROPs. The AMD part has 800 shading units, 40 texture mapping units, and 16 ROPs. The AMD part's higher shading unit count and ROP count suggest a wider parallel architecture, yet the Intel part's higher clock speeds (200 MHz base, 1150 MHz boost for the Intel part versus no recorded core clock for the AMD part) and more efficient design yield higher benchmark scores.

The bus interfaces differ as well. The Intel Iris Pro Graphics 5200 uses a Ring Bus interface, reflecting its integrated nature, while the AMD Radeon HD 6770 uses a PCIe 2.0 x16 interface. The AMD part is a dual-slot card measuring 198 mm (7.8 inches) in length, while the Intel part is an IGP with no physical dimensions recorded and motherboard-dependent display outputs. The AMD part offers 2x DVI, 1x HDMI 1.3a, and 2x mini-DisplayPort 1.1 outputs.

API support shows a split. The Intel part supports DirectX 12 (11_1), OpenGL 4.3, and Vulkan 1.0. The AMD part supports DirectX 11.2 (11_0) and OpenGL 4.4, but has no Vulkan support recorded. The Intel part's Vulkan support is a significant feature advantage, as it enables modern cross-platform graphics APIs that the AMD part cannot access. The AMD part's OpenGL 4.4 support is slightly newer than the Intel part's 4.3, but the Intel part's broader API coverage, particularly Vulkan, gives it a forward-looking edge.

The production status for both parts is end-of-life. The AMD Radeon HD 6770 was released on January 20, 2011, while the Intel Iris Pro Graphics 5200 was released on June 2, 2013. The AMD part's predecessor is Evergreen and its successor is Southern Islands, while the Intel part has no recorded predecessor or successor.
