AMD Radeon HD 7770M vs NVIDIA GeForce RTX 3050 Ti Mobile Comparison

Head-to-Head Benchmarks

The AMD Radeon HD 7770M and NVIDIA GeForce RTX 3050 Ti Mobile occupy nearly identical positions in the overall GPU hierarchy, but their benchmark portfolios tell starkly different stories. The HD 7770M posts a Geekbench Metal score of 13,536, placing it at the 54th percentile of all GPUs, while the RTX 3050 Ti Mobile averages 12,940 across its benchmark suite, sitting at the 53rd percentile. That 596-point average gap is less than five percent, yet the two GPUs achieve this parity through entirely different workloads.

In the only directly comparable metric — the average benchmark score — the HD 7770M leads by a slim margin. Its 13,536 average is 0.1% ahead of the AMD Radeon RX 9070 XT (13,543) and 0.2% ahead of the NVIDIA GeForce GTX 570 (13,515). This places the older chip in remarkably fast company for a 2012 mobile part. The RTX 3050 Ti Mobile, by contrast, averages 12,940, which puts it 0.1% behind the AMD Radeon RX 580 (12,928) and 0.4% behind the NVIDIA GeForce GTX 1660 SUPER (12,986). The delta between the two cards' nearest rivals is similarly tight, suggesting both GPUs sit in a crowded performance band where single percentage points separate competitors.

The RTX 3050 Ti Mobile shows its strength in compute-oriented workloads. Its Geekbench OpenCL score of 57,915 and Vulkan score of 55,812 demonstrate substantial raw throughput, while its Passmark GPU Compute result of 4,305 confirms strong general-purpose performance. The HD 7770M has no comparable compute scores in the data pack, so direct comparison is impossible. However, the RTX 3050 Ti Mobile's Passmark G3D score of 10,093 dwarfs the HD 7770M's single Metal benchmark, though these tests measure different APIs and workloads.

The RTX 3050 Ti Mobile also shows notable variance across DirectX versions in Passmark testing. It scores 120 in DirectX 9, 76 in DirectX 11, 60 in DirectX 10, and 49 in DirectX 12. This pattern suggests the architecture handles legacy APIs more efficiently than modern ones, at least in synthetic testing. The HD 7770M's Metal score of 13,536 cannot be directly mapped to these Passmark results, but its 54th percentile ranking indicates it remains competitive in Apple's graphics API.

Architecture Differences

The generational gap between these two GPUs is dramatic. The HD 7770M uses the Chelsea chip built on GCN 1.0 architecture, fabricated on TSMC's 28 nm process. It packs 1,500 million transistors into a 123 mm² die, yielding a transistor density of 12.2 million per square millimeter. The RTX 3050 Ti Mobile employs the GA106 chip on NVIDIA's Ampere architecture, built on Samsung's 8 nm process. This larger chip contains 12,000 million transistors across 276 mm², achieving a far higher density of 43.5 million per square millimeter.

The NVIDIA part ships with 2,560 shading units, 80 texture mapping units, and 32 raster output pipelines. It also includes 20 ray tracing cores and 80 tensor cores, features entirely absent from the older AMD chip. The HD 7770M offers 512 shading units, 32 TMUs, and 16 ROPs. This eight-fold difference in shader count is partially offset by clock speeds: the RTX 3050 Ti Mobile runs at 735 MHz base and 1,035 MHz boost, while the HD 7770M's clock speeds are not listed in the data pack. Memory configurations differ substantially as well. The RTX 3050 Ti Mobile uses 4 GB of GDDR6 memory at 1,500 MHz (12 Gbps effective) across a 128-bit bus, delivering 192.0 GB/s bandwidth. The HD 7770M uses 1 GB of GDDR5 at 1,000 MHz (4 Gbps effective) on the same 128-bit bus, yielding just 64.00 GB/s.

The memory bandwidth gap is enormous — the RTX 3050 Ti Mobile offers three times the bandwidth of the HD 7770M. This affects everything from texture streaming to compute workloads. The RTX 3050 Ti Mobile also delivers far higher fill rates: 33.12 GPixel/s pixel rate and 82.80 GTexel/s texture rate versus 10.80 GPixel/s and 21.60 GTexel/s on the HD 7770M. Floating point performance follows the same pattern, with the RTX 3050 Ti Mobile achieving 5.299 TFLOPS FP32 and identical 5.299 TFLOPS FP16 (1:1 ratio), while the HD 7770M manages just 691.2 GFLOPS FP32 and has no listed FP16 capability.

Power consumption differs dramatically. The HD 7770M draws 32 W TDP, while the RTX 3050 Ti Mobile consumes 75 W. This makes the AMD part far more power-efficient per FLOP for basic tasks, but the sheer performance ceiling of the NVIDIA chip requires that additional power envelope. The bus interface also reflects the generational divide: PCIe 2.0 x16 on the HD 7770M versus PCIe 4.0 x16 on the RTX 3050 Ti Mobile.

Where Each One Wins

The HD 7770M wins in the narrow category of Metal API performance. Its Geekbench Metal score of 13,536 places it at the 54th percentile of all GPUs, which is slightly higher than the RTX 3050 Ti Mobile's 53rd percentile overall ranking. For applications that rely heavily on Apple's Metal graphics API — particularly macOS-based creative workloads — the older AMD chip remains surprisingly competitive. Its 32 W TDP also makes it suitable for thinner, lighter portable devices where thermal headroom is minimal.

The RTX 3050 Ti Mobile wins across virtually every other measurable dimension. Its Passmark G3D score of 10,093 indicates strong DirectX-based gaming performance, and its compute scores — 57,915 in OpenCL, 55,812 in Vulkan, and 4,305 in GPU Compute — demonstrate versatility across different compute paradigms. The 4 GB GDDR6 memory capacity and 192.0 GB/s bandwidth provide headroom for modern game textures and larger data sets. The inclusion of 20 ray tracing cores and 80 tensor cores enables hardware-accelerated ray tracing and DLSS-style features that the HD 7770M cannot support.

For modern gaming, the RTX 3050 Ti Mobile is the clear choice. Its DirectX 12 Ultimate support (12_2) versus the HD 7770M's DirectX 12 (11_1) means newer games can leverage advanced rendering features on the NVIDIA part. Vulkan 1.4 support on the RTX 3050 Ti Mobile also exceeds the HD 7770M's Vulkan 1.2.170, ensuring broader API compatibility with current and future titles. The RTX 3050 Ti Mobile's higher pixel rate (33.12 GPixel/s) and texture rate (82.80 GTexel/s) translate directly to better performance at higher resolutions and with more complex shaders.

For content creation, the RTX 3050 Ti Mobile's FP16 performance at a 1:1 ratio with FP32 (both 5.299 TFLOPS) is particularly relevant. Many creative applications use FP16 for machine learning inferencing and certain image processing tasks. The HD 7770M's lack of listed FP16 capability means it cannot accelerate these workloads. The NVIDIA part's tensor cores further enhance AI-related tasks, though specific benchmark scores for these features are not included in the data pack.
