AMD Radeon HD 6850 X2 vs Intel UHD Graphics 710 Comparison

AMD Radeon HD 6850 X2 vs Intel UHD Graphics 710

The AMD Radeon HD 6850 X2 and Intel UHD Graphics 710 represent two very different approaches to graphics processing, separated by over a decade of silicon evolution. The AMD card is a dual-GPU behemoth from the Northern Islands era, built on TSMC's 40 nm process with a staggering 1,700 million transistors, while the Intel solution is a power-sipping integrated graphics processor embedded in Alder Lake silicon. Benchmark data shows the AMD part edges ahead in raw compute performance, but the Intel chip counters with modern API support and a dramatically lower power envelope, making this comparison less about a single winner and more about identifying the right tool for distinctly different workloads.

Head-to-Head Benchmarks

The only directly comparable benchmark between these two GPUs is Geekbench OpenCL, and the results show the AMD Radeon HD 6850 X2 taking a decisive victory. The AMD card scores 3977 points, while the Intel UHD Graphics 710 manages 3496 points in the same test, giving the AMD part a 13.8% advantage. This is a meaningful gap in raw compute throughput, reflecting the massive difference in shading hardware: the HD 6850 X2 fields 960 shading units, 48 texture mapping units, and 32 ROPs, whereas the Intel chip is limited to 128 shading units, 8 TMUs, and 8 ROPs.

The delta becomes even more pronounced when examining theoretical peak performance figures from the specification sheet. The AMD card delivers 1.536 TFLOPS of FP32 compute, while the Intel UHD Graphics 710 manages just 332.8 GFLOPS — a difference of roughly 4.6 times in favor of the AMD part. Similarly, pixel throughput tells a lopsided story: the HD 6850 X2 achieves 25.60 GPixel/s versus 10.40 GPixel/s for the Intel chip, and texture fill rates stand at 38.40 GTexel/s versus 10.40 GTexel/s, respectively.

However, the Intel part does have a counterpoint in the form of its Vulkan score. While no direct Vulkan benchmark exists for the AMD card in this dataset, the Intel UHD Graphics 710 posts a Geekbench Vulkan score of 4088, which is higher than its own OpenCL result of 3496 and even surpasses the AMD card's OpenCL score of 3977. This suggests that in modern graphics APIs, the Intel architecture's more efficient design can partially offset its raw hardware disadvantage, particularly in workloads that leverage the newer command processing and scheduling features of Vulkan.

Looking at the broader competitive landscape, both GPUs sit in the lower quartile of all graphics cards. The AMD Radeon HD 6850 X2 holds a 24th percentile ranking, while the Intel UHD Graphics 710 sits at the 22nd percentile. The AMD card's nearest rivals are the NVIDIA Quadro K2000 (3964, 0.3% behind), NVIDIA GeForce 830M (3957, 0.5% behind), AMD Radeon R5 M420 (3956, 0.5% behind), and NVIDIA GeForce GT 745M (3953, 0.6% behind). For the Intel chip, its closest competitors include the NVIDIA GeForce GTX 650 (3823, 0.8% ahead), NVIDIA GeForce MX110 (3834, 1.1% ahead), NVIDIA GeForce GT 635M (3740, 1.4% behind), and NVIDIA Quadro 3000M (3718, 2% behind). These rival positions confirm that both GPUs occupy a similar performance tier, despite their vastly different architectures and release dates.

Where Each One Wins

The AMD Radeon HD 6850 X2 is the clear winner in scenarios demanding raw computational throughput. Its OpenCL performance advantage of 13.8% over the Intel chip makes it the better choice for general-purpose GPU compute tasks such as OpenCL-based rendering, physics simulation, or data-parallel workloads that can leverage its 960 shading units and 1.536 TFLOPS of FP32 compute. The dual-GPU nature of the card, combined with 2 GB of dedicated GDDR5 memory on a 256-bit bus delivering 134.4 GB/s of bandwidth, means it can handle memory-intensive operations without the bottleneck of sharing system memory. For legacy DirectX 11 applications — the HD 6850 X2 supports DirectX 11.2 (11_0) — the AMD card's higher pixel and texture fill rates provide a tangible advantage in both gaming and professional 3D applications from that era.

The Intel UHD Graphics 710 wins in efficiency and modern software compatibility. Its 15 W TDP is minuscule compared to the AMD card's 254 W TDP, making it suitable for compact, passively cooled systems where power consumption and thermal output are primary constraints. The Intel chip supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4, whereas the AMD card is limited to DirectX 11.2 and OpenGL 4.4 with no Vulkan support listed. This means the Intel solution can run modern games and applications that require DX12 or Vulkan, even if at lower frame rates, while the AMD card is locked out of those titles entirely. The Intel chip's Vulkan score of 4088, which exceeds the AMD card's best OpenCL result, suggests it may actually deliver superior performance in Vulkan-based workloads despite its smaller hardware footprint.

For memory flexibility, the Intel UHD Graphics 710 uses system shared memory with system-dependent bandwidth, which allows it to scale with whatever RAM is installed in the host system. The AMD card, by contrast, is confined to its fixed 2 GB GDDR5 allocation. This makes the Intel solution more adaptable for general productivity tasks where the GPU needs to access large datasets that exceed 2 GB, albeit at slower effective bandwidth.

Specification Differences

The two GPUs differ across nearly every specification category. The AMD Radeon HD 6850 X2 uses the Barts chip on TSMC's 40 nm process with 1,700 million transistors and a 255 mm² die size, while the Intel UHD Graphics 710 uses an Alder Lake chip on Intel's 10 nm process with no transistor or die size data available. Clock speeds differ fundamentally: the AMD card has no base or boost clock listed but runs memory at 1050 MHz (4.2 Gbps effective), while the Intel chip has a 300 MHz base clock and 1300 MHz boost clock with system shared memory.

Memory configurations are entirely different. The AMD card features 2 GB GDDR5 on a 256-bit bus with 134.4 GB/s bandwidth, whereas the Intel solution uses system shared memory with system-dependent bandwidth. The AMD card has 960 shading units, 48 TMUs, and 32 ROPs, compared to 128 shading units, 8 TMUs, and 8 ROPs for the Intel chip. Pixel rates are 25.60 GPixel/s versus 10.40 GPixel/s, texture rates are 38.40 GTexel/s versus 10.40 GTexel/s, and FP32 compute is 1.536 TFLOPS versus 332.8 GFLOPS — the Intel chip additionally offers 665.6 GFLOPS of FP16 performance with a 2:1 ratio.

Power and physical specifications diverge sharply. The AMD card has a 254 W TDP, requires a 600 W suggested PSU, is dual-slot, and uses 2x 8-pin power connectors, while the Intel chip has a 15 W TDP, is an IGP with no power connectors, and requires no separate PSU recommendation. The AMD card uses a PCIe 2.0 x16 interface and offers 2x DVI, 1x HDMI 1.3a, and 1x DisplayPort 1.1 outputs, while the Intel chip uses a Ring Bus interface with motherboard-dependent display outputs. API support also differs: DirectX 11.2 versus 12 (12_1), OpenGL 4.4 versus 4.6, and Vulkan absent versus 1.4.

Architecture Differences

The architectural divide between these two GPUs is generational and profound. The AMD Radeon HD 6850 X2 is built on TeraScale 2 architecture, part of the Northern Islands (HD 6800) generation, and represents a multi-chip design where two Barts GPUs work in tandem. This architecture dates from a period when discrete graphics cards were the only viable path to serious 3D performance, and it shows in the design priorities: massive shading arrays, dedicated high-speed memory, and aggressive power delivery. The 40 nm process node from TSMC was state-of-the-art at the time, but it necessitated the 254 W TDP and dual-slot cooling solution.

The Intel UHD Graphics 710, in contrast, is built on Generation 12.2 architecture and comes from the HD Graphics (Alder Lake) generation. It is an integrated graphics processor, sharing the die with CPU cores and using the Ring Bus interface to access system memory. The 10 nm Intel process allows for dramatically better power efficiency — 15 W versus 254 W — while still providing competitive performance through architectural efficiency rather than raw hardware count. The Intel chip integrates modern features like FP16 support with a 2:1 ratio, which the AMD card lacks entirely, and it supports the Vulkan 1.4 API, reflecting a decade of graphics API evolution.

The transistor count tells the story of different design philosophies. The AMD card packs 1,700 million transistors into a 255 mm² die, achieving a density of 6.7M transistors per mm². While no transistor data exists for the Intel chip, its 128 shading units against the AMD's 960 shows how integrated graphics have leveraged architectural improvements to deliver usable performance with a fraction of the hardware. The AMD card's predecessor was Evergreen, and its successor was Southern Islands, positioning it in a clear lineage of discrete graphics evolution. The Intel chip has no listed predecessor or successor, reflecting its role as a flexible integrated solution that adapts to the host processor rather than following a discrete GPU product cycle.
