AMD Radeon HD 6770 vs Intel UHD Graphics 710 Comparison

Intel UHD Graphics 710 and AMD Radeon HD 6770 are both end-of-life graphics solutions that land in the 22nd percentile of all GPUs, but they achieve that ranking through wildly different architectures and eras. The data shows a narrow victory for the older AMD card in the only shared benchmark, yet the Intel part offers modern API support and a dramatically lower power draw, making the choice heavily dependent on the intended use case.

Head-to-Head Benchmarks

The sole direct comparison available is the Geekbench OpenCL test, and it favors the AMD Radeon HD 6770. AMD scores 3649 against Intel’s 3496, a delta of -4.2% from Intel’s perspective. That is a margin of roughly 4.4% in AMD’s favor—close enough that it falls within typical run-to-run variance, but the result is consistent with the raw compute specifications. The HD 6770 delivers 1,360.0 GFLOPS of FP32 throughput, while the UHD 710 manages only 332.8 GFLOPS. That is a 4.1x difference in theoretical floating-point performance, yet the benchmark gap is just 4.2%. This suggests the OpenCL workload is not purely compute-bound or that the Intel driver extracts disproportionately more efficiency from its limited hardware.

In contrast, the nearest rival data places both cards in similar company. The UHD 710’s average benchmark score is 3792, which sits 0.8% below an NVIDIA GeForce GTX 650 (3823) and 1.4% above a GeForce GT 635M (3740). The HD 6770’s average score is 3649, which is 0.6% above a GeForce GTX 1050 (3629) and 0.9% above a GeForce GT 735M (3616). Notably, the HD 6770’s nearest rivals include an RTX 5000 Mobile Ada Generation at 3596, where the AMD card leads by 1.5%. This indicates that while the HD 6770 wins the direct head-to-head, neither card is decisively faster than a cluster of older and mid-range NVIDIA parts.

The absence of a Geekbench Vulkan score for the HD 6770 is telling. The UHD 710 scores 4088 in Vulkan, which is its stronger result compared to its OpenCL score of 3496. This 16.9% improvement suggests the Intel architecture benefits from a modern, low-level API. Since the AMD card has no Vulkan entry in the data, its performance in that API is unknown, but its TeraScale 2 architecture predates Vulkan support entirely, as evidenced by its null Vulkan API listing.

Architecture Differences

The two GPUs come from opposite ends of the hardware spectrum. Intel’s UHD Graphics 710 is built on the Alder Lake chip using Generation 12.2 architecture, fabricated on a 10 nm process at Intel. It is an integrated graphics processor (IGP) with a Ring Bus interface, meaning it shares system memory and has no dedicated VRAM. The AMD Radeon HD 6770 is a discrete card based on the Juniper chip, using the much older TeraScale 2 architecture, produced on a 40 nm process at TSMC. The HD 6770 packs 1,040 million transistors on a 166 mm² die, giving a transistor density of 6.3M / mm²; the UHD 710’s transistor count and die size are not listed.

The compute resources differ drastically. The HD 6770 has 800 shading units, 40 texture mapping units (TMUs), and 16 render output units (ROPs). The UHD 710 has 128 shading units, 8 TMUs, and 8 ROPs. That is a 6.25x advantage in shading units and a 5x advantage in TMUs for AMD, but only a 2x advantage in ROPs. The pixel rate reflects this: the HD 6770 outputs 13.60 GPixel/s versus 10.40 GPixel/s for Intel. The texture rate gap is larger—34.00 GTexel/s versus 10.40 GTexel/s—because the AMD card has five times the TMUs.

Memory architecture is a fundamental differentiator. The UHD 710 uses System Shared memory with System Dependent bandwidth, while the HD 6770 has 1024 MB of dedicated GDDR5 on a 128-bit bus, delivering 76.80 GB/s of bandwidth. The AMD card’s memory clock is 1200 MHz (4.8 Gbps effective). The Intel part’s memory clock is also listed as System Shared, so no direct comparison is possible, but the dedicated GDDR5 on a 128-bit bus gives the HD 6770 a clear bandwidth advantage for texture-heavy workloads.

API support is the reverse story. The UHD 710 supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The HD 6770 is limited to DirectX 11.2 (11_0) and OpenGL 4.4, with no Vulkan support. This makes the Intel part forward-compatible with modern game engines and compute frameworks, while the AMD card is locked to older API levels. The power envelope is also starkly different: the UHD 710 has a 15 W TDP and is an IGP, while the HD 6770 has a 108 W TDP, is dual-slot, requires a single 6-pin power connector, and needs a 300 W suggested PSU.

Where Each One Wins

The AMD Radeon HD 6770 wins in raw compute throughput and memory bandwidth. With 1,360.0 GFLOPS FP32 performance, 76.80 GB/s of dedicated GDDR5 bandwidth, and a 34.00 GTexel/s texture rate, it is the clear choice for any workload that saturates shading units or relies on high-bandwidth texture fetching. Its 800 shading units and 40 TMUs are well-suited for older DirectX 11-era games and OpenCL compute tasks that were designed for that generation of hardware. The HD 6770 also wins the OpenCL benchmark directly, 3649 to 3496, and its nearest rivals include the GTX 1050, indicating it can hold its own against much newer entry-level discrete cards in compute tests.

The Intel UHD Graphics 710 wins in efficiency, modern API compatibility, and integrated convenience. Its 15 W TDP is a fraction of the HD 6770’s 108 W, and it requires no power connector, no dual-slot heatsink, and no dedicated PSU headroom. The Vulkan score of 4088 shows it can outperform its own OpenCL result by nearly 17%, and the support for DirectX 12_1, OpenGL 4.6, and Vulkan 1.4 means it can run contemporary software stacks that the HD 6770 cannot even load. For systems where the motherboard provides display outputs, the UHD 710 is a zero-additional-cost solution that handles modern desktop compositing, video decode, and light 3D acceleration without the space or power burden of a discrete card.

The data does not support a clear winner for gaming. The HD 6770 has the theoretical edge in fill rate and shading, but its lack of Vulkan and older DirectX 11.2 support limits it to legacy titles. The UHD 710 has modern APIs but only a quarter of the shading units. In the one benchmark where they meet, the HD 6770 wins by 4.2%, but that is a single synthetic test, not a gaming frame-rate comparison.

Specification Differences

The two cards differ across nearly every measurable specification. The process node is 10 nm for Intel versus 40 nm for AMD. The UHD 710 has a base clock of 300 MHz and a boost clock of 1300 MHz; the HD 6770 has no base or boost clock listed. Memory size is System Shared for Intel versus 1024 MB for AMD. Memory type is System Shared versus GDDR5. Bus width is System Shared versus 128 bit. Bandwidth is System Dependent versus 76.80 GB/s. Shading units are 128 versus 800. TMUs are 8 versus 40. ROPs are 8 versus 16. FP32 performance is 332.8 GFLOPS versus 1,360.0 GFLOPS. FP16 performance is 665.6 GFLOPS (2:1) for Intel, with no FP16 data for AMD. TDP is 15 W versus 108 W. Slot width is IGP versus Dual-slot. Power connector is none versus 1x 6-pin. Suggested PSU is not listed versus 300 W. Bus interface is Ring Bus versus PCIe 2.0 x16. Display outputs are Motherboard Dependent versus 2x DVI, 1x HDMI 1.3a, and 2x mini-DisplayPort 1.1. DirectX support is 12 (12_1) versus 11.2 (11_0). OpenGL is 4.6 versus 4.4. Vulkan is 1.4 versus null. The HD 6770 has a length of 198 mm (7.8 inches); the UHD 710 has no dimensions listed.

The Verdict

The data points to a clear split: the AMD Radeon HD 6770 is the superior choice for raw compute performance in legacy DirectX 11 environments. It wins the only head-to-head benchmark by 4.2%, offers 4.1x the FP32 throughput, and has 5x the TMUs and 2x the ROPs. Its dedicated GDDR5 memory with 76.80 GB/s bandwidth is essential for any workload that cannot tolerate system-shared memory bottlenecks. For users running older games, OpenCL applications written for TeraScale-era hardware, or needing a discrete card with dual-DVI and mini-DisplayPort outputs, the HD 6770 is the functional pick. Its 129 USD launch MSRP was modest for the era, and it remains competitive with much newer entry-level parts, as shown by its 0.6% lead over the GeForce GTX 1050.

The Intel UHD Graphics 710 is the logical choice for modern, power-constrained systems. Its 15 W TDP is 93 W lower than the HD 6770, it requires no power connector or extra slot space, and it supports DirectX 12_1, OpenGL 4.6, and Vulkan 1.4. The Vulkan score of 4088 is 16.9% higher than its own OpenCL score, indicating that modern API workloads are its strength. It is also within 0.8% of the GeForce GTX 650 in average score, which is remarkable for an integrated part. For a basic desktop, HTPC, or office machine where the motherboard already provides display outputs, the UHD 710 is the only sensible option—there is no reason to install a 108 W, dual-slot card for a 4.2% OpenCL gain.

Neither card is a gaming champion. The HD 6770’s architectural age limits it to pre-2011 APIs, and the UHD 710’s 128 shading units cap its modern gaming potential. The verdict from the data is straightforward: choose the HD 6770 if you need dedicated memory, high fill rates, and legacy API compatibility. Choose the UHD 710 if you need low power, modern API support, and zero physical footprint. The 22nd percentile ranking for both confirms they are entry-level solutions, but the Intel part’s modern feature set makes it the more future-proof choice despite losing the single benchmark comparison.
