AMD Radeon HD 7950 vs NVIDIA GeForce RTX 5070 Ti Mobile Comparison

# NVIDIA GeForce RTX 5070 Ti Mobile vs AMD Radeon HD 7950

The NVIDIA GeForce RTX 5070 Ti Mobile and AMD Radeon HD 7950 are separated by more than a decade of GPU evolution, and the benchmark data reflects that gulf clearly. The RTX 5070 Ti Mobile sits at the 80th percentile among all GPUs, while the HD 7950 lands at the 78th percentile, but that near-parity in percentile masks a massive gap in raw performance and capability. The RTX 5070 Ti Mobile delivers an average benchmark score of 35,435, while the HD 7950 averages 33,951. That 4.4% average-score gap, however, understates how differently these cards perform across workloads, and the RTX 5070 Ti Mobile's modern feature set makes it the only sensible choice for current software.

The Verdict

The RTX 5070 Ti Mobile is the clear pick for anyone running modern games, compute workloads, or applications that leverage DirectX 12 Ultimate features. It is 4.4% ahead of the HD 7950 in average benchmark score, but that figure comes from a single Geekbench Metal result for the AMD card versus a nine-test suite for the NVIDIA card. The RTX 5070 Ti Mobile scores 143,870 in Geekbench OpenCL and 139,213 in Geekbench Vulkan — tests the HD 7950 simply cannot run at comparable settings due to its lack of modern API support. The HD 7950's only benchmark entry is Geekbench Metal at 33,951, which is 76.4% lower than the RTX 5070 Ti Mobile's OpenCL score. For gaming, the RTX 5070 Ti Mobile's PassMark G3D score of 24,004 dwarfs anything the HD 7950 could produce, and the NVIDIA card supports DirectX 12 Ultimate (12_2) versus the AMD card's DirectX 12 (11_1). The HD 7950 is an end-of-life product from 2012; the RTX 5070 Ti Mobile is an active product released in 2025. There is no scenario where the HD 7950 is the better purchase for new workloads, though its dual-slot design and 2x 6-pin power connectors might appeal to retro-build enthusiasts.

The HD 7950's lone advantage is its 78th percentile ranking, which is only two points below the RTX 5070 Ti Mobile's 80th percentile. That suggests the AMD card remains competitive in certain legacy benchmarks, likely due to its 384-bit memory bus and 3 GB of GDDR5. But the RTX 5070 Ti Mobile has 12 GB of GDDR7, 4x the memory capacity, and 2.8x the bandwidth at 672.0 GB/s versus 240.0 GB/s. The RTX 5070 Ti Mobile's nearest rivals — the Quadro GV100 (-0.2%), Radeon Pro Duo (-1.2%), A2 (+2.1%), and T1000 (-2.4%) — are all professional or workstation cards, indicating its performance class. The HD 7950's nearest rivals — RX 480 (-0.1%), RX 7700S (+0.3%), RX 560 XT (-0.5%), and RTX A2000 12 GB (-0.6%) — are all much newer architectures, which shows how far the HD 7950's architecture has aged.

Where Each One Wins

The RTX 5070 Ti Mobile wins in every compute and modern API scenario. Its Geekbench OpenCL score of 143,870 is 4.2x higher than the HD 7950's Geekbench Metal score of 33,951. The Vulkan score of 139,213 further demonstrates its strength in modern graphics APIs. The PassMark suite shows the NVIDIA card's dominance across DirectX versions: 151 in DirectX 10, 237 in DirectX 11, 102 in DirectX 12, and 259 in DirectX 9. The HD 7950 has no PassMark entries, so direct comparison is impossible, but the RTX 5070 Ti Mobile's PassMark G3D score of 24,004 and GPU compute score of 10,101 indicate strong overall rendering and compute capability. The RTX 5070 Ti Mobile also has 46 RT cores and 184 tensor cores, enabling ray tracing and AI acceleration that the HD 7950 lacks entirely.

The HD 7950's only measurable win is its percentile ranking, which is just 2 points below the RTX 5070 Ti Mobile. In terms of architecture, the HD 7950's 352 mm² die with 4,313 million transistors on a 28 nm process is larger than the RTX 5070 Ti Mobile's 263 mm² die with 31,100 million transistors on a 5 nm process. The AMD card's 384-bit memory bus is double the NVIDIA card's 192-bit bus, though the RTX 5070 Ti Mobile's GDDR7 memory runs at 1750 MHz (28 Gbps effective) versus the HD 7950's 1250 MHz (5 Gbps effective), resulting in the NVIDIA card's 672.0 GB/s bandwidth versus 240.0 GB/s. The HD 7950's 200 W TDP is 3.3x higher than the RTX 5070 Ti Mobile's 60 W TDP, making the NVIDIA card dramatically more power-efficient. The RTX 5070 Ti Mobile is an IGP form factor with no power connectors, while the HD 7950 is a dual-slot card requiring 2x 6-pin connectors and a 550 W suggested PSU.

Architecture Differences

The RTX 5070 Ti Mobile uses the GB205 chip on NVIDIA's Blackwell 2.0 architecture, built on a 5 nm process at TSMC. It packs 31,100 million transistors into a 263 mm² die, achieving a transistor density of 118.3M per mm². The HD 7950 uses the Tahiti chip on AMD's GCN 1.0 architecture, built on a 28 nm process at TSMC, with 4,313 million transistors on a 352 mm² die and a density of 12.3M per mm². The NVIDIA card has 5,888 shading units, 184 TMUs, 80 ROPs, 46 RT cores, and 184 tensor cores. The AMD card has 1,792 shading units, 112 TMUs, and 32 ROPs, with no RT or tensor cores. The RTX 5070 Ti Mobile's FP32 throughput is 17.04 TFLOPS with FP16 at 17.04 TFLOPS (1:1 ratio), while the HD 7950 manages 2.867 TFLOPS FP32 with no FP16 support listed. The pixel rate difference is 115.8 GPixel/s versus 25.60 GPixel/s, and texture rate is 266.2 GTexel/s versus 89.60 GTexel/s — both heavily favoring the NVIDIA card.

The memory subsystems are radically different. The RTX 5070 Ti Mobile has 12 GB of GDDR7 on a 192-bit bus at 672.0 GB/s. The HD 7950 has 3 GB of GDDR5 on a 384-bit bus at 240.0 GB/s. While the AMD card's wider bus is theoretically better for certain memory-bound workloads, the NVIDIA card's faster memory technology and 4x capacity make it far more capable for modern games that exceed 3 GB of VRAM. API support also differs: the RTX 5070 Ti Mobile supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the HD 7950 supports DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.170. The NVIDIA card's newer Vulkan version and DirectX 12 Ultimate feature set enable mesh shaders, variable rate shading, and hardware ray tracing — none of which exist on the AMD card.

Head-to-Head Benchmarks

The only directly comparable benchmark between these two GPUs is Geekbench, where the RTX 5070 Ti Mobile scores 143,870 in OpenCL and 139,213 in Vulkan, while the HD 7950 scores 33,951 in Metal. The OpenCL score is 4.2x higher than the Metal score, and even the NVIDIA card's Vulkan score is 4.1x higher. This indicates the RTX 5070 Ti Mobile is roughly 4x faster in compute-heavy workloads, despite the HD 7950's 78th percentile ranking being only 2 points lower than the NVIDIA card's 80th percentile.

In the PassMark suite, the RTX 5070 Ti Mobile shows strong DirectX performance: 259 in DirectX 9, 151 in DirectX 10, 237 in DirectX 11, and 102 in DirectX 12. The HD 7950 has no PassMark results, so we cannot directly compare these numbers. However, the RTX 5070 Ti Mobile's PassMark G3D score of 24,004 places it well above the HD 7950's average benchmark score of 33,951 when you consider that the G3D test is a composite of multiple rendering workloads. The NVIDIA card's GPU compute score of 10,101 further demonstrates its advantage in parallel processing tasks.

The nearest-rival comparisons provide additional context. The RTX 5070 Ti Mobile sits within 2.4% of the Quadro GV100 (-0.2%), Radeon Pro Duo (-1.2%), A2 (+2.1%), and T1000 (-2.4%) — all professional-grade cards with similar average scores ranging from 34,690 to 36,289. The HD 7950 sits within 0.6% of the RX 480 (-0.1%), RX 7700S (+0.3%), RX 560 XT (-0.5%), and RTX A2000 12 GB (-0.6%), with average scores from 33,849 to 34,154. This shows the HD 7950 is competitive with much newer mid-range cards, but the RTX 5070 Ti Mobile is in a higher performance tier altogether.
