AMD Radeon HD 6770 vs NVIDIA RTX 5000 Mobile Ada Generation Comparison

The AMD Radeon HD 6770 and the NVIDIA RTX 5000 Mobile Ada Generation represent two extremes of GPU design, separated by over a decade of architectural evolution. The data shows that while the newer RTX 5000 Mobile Ada Generation carries overwhelming hardware specifications, the older HD 6770 actually posts a higher average benchmark score in the available dataset, making this comparison less straightforward than raw specs suggest.

Head-to-Head Benchmarks

The benchmark data presents a surprising outcome. The AMD Radeon HD 6770 records an average benchmark score of 3649, while the NVIDIA RTX 5000 Mobile Ada Generation scores 3596. This gives the HD 6770 a 1.5% advantage over the RTX 5000 Mobile Ada Generation in the head-to-head comparison. The deltaPct values from the nearest rivals confirm this narrow margin, with the HD 6770 sitting 1.5% above the RTX 5000 Mobile Ada Generation, while the RTX 5000 Mobile Ada Generation sits 1.5% below the HD 6770.

When placed against the broader field, both GPUs occupy nearly identical percentile positions. The HD 6770 ranks at the 22nd percentile among all GPUs, while the RTX 5000 Mobile Ada Generation ranks at the 21st percentile. This means that despite the massive architectural differences, neither card breaks into the upper echelons of the benchmark database, and they land within 1 percentile point of each other.

Looking at the nearest rivals for each card further illustrates the tight clustering. The HD 6770's closest competitor is the NVIDIA GeForce GTX 1050 with an average score of 3629, just 0.6% behind the AMD card. The NVIDIA GeForce GT 735M scores 3616, 0.9% behind, while the NVIDIA GeForce 825M scores 3694, putting it 1.2% ahead of the HD 6770. For the RTX 5000 Mobile Ada Generation, the NVIDIA GeForce GT 545 scores 3594 (0.1% behind), the GT 735M scores 3616 (0.6% ahead), and the GTX 1050 scores 3629 (0.9% ahead). The benchmark results indicate that both cards are essentially trading blows with mid-range and even entry-level GPUs from different eras, rather than the RTX 5000 Mobile Ada Generation dominating as its specifications might suggest.

It is important to note that the benchmark tests differ between the two cards. The HD 6770 was tested using Geekbench OpenCL, while the RTX 5000 Mobile Ada Generation was tested using 3DMark Steel Nomad DX12. These are different workloads, with OpenCL being a general-purpose compute test and 3DMark Steel Nomad DX12 being a modern gaming-oriented DirectX 12 benchmark. This methodological difference likely explains why the older card appears competitive, as the HD 6770's score comes from a compute workload that may favor its architecture differently than a modern DX12 gaming benchmark would.

Where Each One Wins

The HD 6770 wins in raw benchmark score, posting 3649 versus 3596, a 1.5% margin. This is its only measurable victory, but it is the metric that defines the head-to-head comparison. The card also holds advantages in physical dimensions, being a dual-slot design with a 198 mm length, which makes it a tangible, installable component in a desktop system. Its display outputs include 2x DVI, 1x HDMI 1.3a, and 2x mini-DisplayPort 1.1, offering multi-monitor connectivity out of the box.

The RTX 5000 Mobile Ada Generation wins in every architectural and specification category that matters for modern workloads. It has 9728 shading units versus 800, 304 TMUs versus 40, and 112 ROPs versus 16. Its FP32 compute throughput is 41.15 TFLOPS compared to 1360.0 GFLOPS for the HD 6770, a difference of roughly 30 times. The RTX 5000 Mobile Ada Generation also features 76 RT cores and 304 tensor cores, enabling hardware ray tracing and AI acceleration that the HD 6770 completely lacks. Memory capacity is 16 GB versus 1024 MB, with bandwidth of 576.0 GB/s versus 76.80 GB/s. The RTX 5000 Mobile Ada Generation supports DirectX 12 Ultimate, Vulkan 1.4, and OpenGL 4.6, while the HD 6770 tops out at DirectX 11.2, OpenGL 4.4, and has no Vulkan support.

Architecture Differences

The architectural gap between these two GPUs is generational. The HD 6770 uses the Juniper chip built on TeraScale 2 architecture, manufactured on TSMC's 40 nm process. It packs 1,040 million transistors into a 166 mm² die, yielding a transistor density of 6.3 million transistors per square millimeter. This is a fixed-function design from 2011, with no dedicated ray tracing or tensor cores, and its shading units operate in a VLIW-style arrangement typical of the TeraScale era.

The RTX 5000 Mobile Ada Generation uses the AD103 chip built on Ada Lovelace architecture, manufactured on TSMC's 5 nm process. It contains 45,900 million transistors in a 379 mm² die, achieving a transistor density of 121.1 million transistors per square millimeter. This is nearly 20 times the transistor density of the HD 6770. The Ada Lovelace architecture is designed around modern workloads, with dedicated RT cores for ray tracing, tensor cores for AI and DLSS, and a unified shader architecture that delivers 41.15 TFLOPS of FP32 and FP16 performance at a 1:1 ratio. The HD 6770 has no listed FP16 capability, reflecting its older compute design.

The foundry is the same for both — TSMC — but the process node is entirely different. The 40 nm node of 2011 was advanced for its time, while the 5 nm node of 2023 represents a massive leap in manufacturing capability. This is why the RTX 5000 Mobile Ada Generation can fit 45,900 million transistors into a die that is only slightly more than twice the area of the HD 6770's 166 mm².

Specification Differences

The specifications that differ between the two cards are extensive. The HD 6770 has a memory clock of 1200 MHz with 4.8 Gbps effective transfer rate, while the RTX 5000 Mobile Ada Generation has a base clock of 1425 MHz and a boost clock of 2115 MHz, with memory running at 2250 MHz and 18 Gbps effective. The HD 6770 has no base or boost clock listed, only its memory clock.

Memory configuration differs dramatically: 1024 MB of GDDR5 on a 128-bit bus versus 16 GB of GDDR6 on a 256-bit bus. This yields bandwidth of 76.80 GB/s versus 576.0 GB/s, an 8x difference. The pixel rate is 13.60 GPixel/s versus 236.9 GPixel/s, and the texture rate is 34.00 GTexel/s versus 643.0 GTexel/s.

Power and physical characteristics also diverge. The HD 6770 has a TDP of 108 W, requires a 300 W suggested PSU, uses a dual-slot cooler, and needs a 1x 6-pin power connector. The RTX 5000 Mobile Ada Generation has a TDP of 120 W, requires no external power connectors, and is an IGP (integrated graphics processor) form factor, meaning it is designed for mobile workstations. The HD 6770 uses PCIe 2.0 x16, while the RTX 5000 Mobile Ada Generation uses PCIe 4.0 x16.

The production status and release dates tell the story of their lifecycles. The HD 6770 was released on January 20, 2011, with a launch MSRP of 129 USD, and is now end-of-life. Its predecessor was Evergreen and its successor was Southern Islands. The RTX 5000 Mobile Ada Generation was released on March 20, 2023, is still active, had no launch MSRP listed, and its predecessor was Ampere-MW with successor Blackwell-MW.

The Verdict

The data presents a paradox. By raw benchmark score, the AMD Radeon HD 6770 wins, but this is almost certainly a reflection of the different benchmark workloads used rather than true performance equivalence. The HD 6770 was tested on Geekbench OpenCL, a compute test that may not stress modern gaming features, while the RTX 5000 Mobile Ada Generation was tested on 3DMark Steel Nomad DX12, a demanding DirectX 12 gaming benchmark.

For anyone building a system today, the RTX 5000 Mobile Ada Generation is the only rational choice, despite its lower benchmark score in this dataset. It offers 16 GB of GDDR6 memory versus 1 GB of GDDR5, 41.15 TFLOPS of FP32 compute versus 1,360.0 GFLOPS, hardware ray tracing, tensor cores, Vulkan support, and modern DirectX 12 Ultimate. The HD 6770, while scoring higher on this particular OpenCL test, is an end-of-life product from 2011 with no modern API support and a 40 nm process that cannot compete on any modern workload.

The benchmark results indicate that the HD 6770's 1.5% score advantage is a statistical artifact of comparing different test methodologies. The RTX 5000 Mobile Ada Generation is the clear winner for any real-world application, but the data does show that the HD 6770 was a capable card in its era, holding its own against much newer hardware in at least one compute metric. For a builder with a modern system, the RTX 5000 Mobile Ada Generation is the pick. For a retro enthusiast documenting legacy hardware, the HD 6770's benchmark showing is a curiosity worth noting.
