AMD Radeon HD 7970 vs NVIDIA GeForce RTX 5070 Ti Mobile Comparison

The NVIDIA GeForce RTX 5070 Ti Mobile and the AMD Radeon HD 7970 represent two vastly different eras of GPU design, and the benchmark data reflects a generational chasm. In the single available head-to-head test, the modern Blackwell laptop part utterly dominates the decade-old GCN flagship, but the comparison offers more nuance than a simple score difference when examining architecture and intended use cases.

Head-to-Head Benchmarks

The only directly comparable benchmark in the data is Geekbench OpenCL, and the result is a landslide. The NVIDIA GeForce RTX 5070 Ti Mobile scores 143,870 points, while the AMD Radeon HD 7970 manages 34,541 points. That translates to a delta of 316.5% in favor of the RTX 5070 Ti Mobile — the newer card is roughly four times faster in this compute-oriented workload. This is not a marginal improvement; it is a complete reset of performance expectations.

When placed against the broader market, the RTX 5070 Ti Mobile sits at the 80th percentile of all GPUs, with an average benchmark score of 35,435. Its nearest rivals include the NVIDIA Quadro GV100 (average score 35,520, delta -0.2%), the AMD Radeon Pro Duo (35,860, -1.2%), and the NVIDIA T1000 (36,289, -2.4%). The data shows the RTX 5070 Ti Mobile is essentially neck-and-neck with these professional-grade cards, trailing the T1000 by just 2.4% despite being a mobile part. In contrast, the HD 7970 holds the 79th percentile with an average score of 34,541, placing it just below the RTX 5070 Ti Mobile in overall standing. Its nearest rival is the NVIDIA T1000 8 GB (34,561, -0.1%), meaning the HD 7970 is only 0.1% behind that card — a statistical tie.

The deltaPct figures are telling. The RTX 5070 Ti Mobile leads the NVIDIA A2 by 2.1% and trails the Quadro GV100 by just 0.2%, showing it competes with workstation silicon. The HD 7970, meanwhile, beats the NVIDIA TITAN V by 0.5% and the RTX A1000 by 1% but loses to the A2 by 0.4%. These rivalries indicate that while the HD 7970 is ancient, its raw compute in OpenCL still holds up against low-end modern workstation cards. However, the head-to-head margin of 316.5% is the decisive number — there is no benchmark where the HD 7970 wins.

FAQ

Architecture Differences

The architectural gap is the core of this comparison. The RTX 5070 Ti Mobile uses the GB205 chip built on Blackwell 2.0 architecture, manufactured on a 5 nm process at TSMC. It contains 31,100 million transistors on a 263 mm² die, yielding a density of 118.3 million transistors per mm². The HD 7970, by contrast, uses the Tahiti chip with GCN 1.0 architecture on a 28 nm process. It has 4,313 million transistors on a larger 352 mm² die, giving a density of just 12.3 million per mm². The RTX 5070 Ti Mobile crams over seven times more transistors into a smaller physical area.

The shader configuration reflects this. The RTX 5070 Ti Mobile has 5,888 shading units, 184 TMUs, and 80 ROPs. The HD 7970 has 2,048 shading units, 128 TMUs, and only 32 ROPs. The newer GPU also adds 46 RT cores and 184 tensor cores — hardware the HD 7970 lacks entirely, as it predates ray tracing and AI acceleration. Clock speeds tell a similar story: the RTX 5070 Ti Mobile runs at a base of 847 MHz and boosts to 1,447 MHz, while the HD 7970's clocks are not listed in the data. Memory bandwidth heavily favors the new part: 672.0 GB/s versus 264.0 GB/s, achieved with GDDR7 on a narrower 192-bit bus versus GDDR5 on a 384-bit bus.

Fill rates and compute throughput are equally lopsided. The RTX 5070 Ti Mobile delivers 115.8 GPixel/s and 266.2 GTexel/s, with FP32 performance of 17.04 TFLOPS. The HD 7970 manages 29.60 GPixel/s and 118.4 GTexel/s, with FP32 at 3.789 TFLOPS. The RTX 5070 Ti Mobile also supports FP16 at a 1:1 ratio (17.04 TFLOPS), while the HD 7970 has no listed FP16 capability. Power and physical design differ starkly: the RTX 5070 Ti Mobile is an IGP with 60 W TDP and no power connectors, while the HD 7970 is a dual-slot card at 250 W TDP requiring a 600 W PSU and 1x 6-pin plus 1x 8-pin connectors. The HD 7970 measures 275 mm long, 111 mm tall, and 38 mm wide.

The Verdict

The data supports only one conclusion for raw performance: the NVIDIA GeForce RTX 5070 Ti Mobile is categorically superior. It wins the sole head-to-head benchmark by 316.5%, has a higher average benchmark score (35,435 versus 34,541), and holds a higher percentile rank (80th versus 79th). It also offers modern features — ray tracing cores, tensor cores, DirectX 12 Ultimate, and Vulkan 1.4 — that the HD 7970 cannot match. The HD 7970's only statistical advantage is its proximity to certain workstation rivals, but those deltas (0.1% to 1%) are negligible in real-world terms.

However, the HD 7970 is not without context. It is end-of-life, while the RTX 5070 Ti Mobile is active. The HD 7970's 3 GB of memory and 264.0 GB/s bandwidth are woefully insufficient for modern workloads, but its 384-bit bus and 29.60 GPixel/s fill rate were respectable in its era. The RTX 5070 Ti Mobile's 60 W TDP makes it viable for laptops, whereas the HD 7970's 250 W TDP demands a desktop with a 600 W PSU. If the choice is between these two, the RTX 5070 Ti Mobile is the only rational pick for any current task. The HD 7970 is a historical artifact that happens to still score near the 79th percentile in compute benchmarks.

Where Each One Wins

The RTX 5070 Ti Mobile wins everywhere that matters for modern use. In OpenCL compute, it is 316.5% ahead. It has 4x the memory capacity (12 GB versus 3 GB) and over 2.5x the memory bandwidth (672.0 GB/s versus 264.0 GB/s). Its FP32 throughput of 17.04 TFLOPS dwarfs the HD 7970's 3.789 TFLOPS, and it adds FP16 support that the older card lacks entirely. For any workload involving ray tracing, AI inference, or modern API features like DirectX 12 Ultimate, the HD 7970 is not a contender. The RTX 5070 Ti Mobile's 46 RT cores and 184 tensor cores are absent from the HD 7970, making the newer card the only option for those tasks.

The HD 7970's wins are narrower and more historical. It has a wider memory bus (384-bit versus 192-bit), which theoretically benefits certain bandwidth-sensitive legacy workloads, but its lower bandwidth (264.0 GB/s) negates that advantage in practice. Its dual-slot desktop form factor with 1x DVI, 1x HDMI 1.4a, and 2x mini-DisplayPort 1.2 outputs provides fixed display connectivity, whereas the RTX 5070 Ti Mobile's outputs are portable-device dependent. In percentile terms, the HD 7970's 79th percentile is only one point below the RTX 5070 Ti Mobile's 80th, and it ties or beats some modern workstation cards (NVIDIA TITAN V by 0.5%, RTX A1000 by 1%). For a legacy system running old software that cannot utilize modern features, the HD 7970 might still function, but the data shows no performance scenario where it outruns the RTX 5070 Ti Mobile. The verdict is unambiguous: the RTX 5070 Ti Mobile is the superior GPU by every measurable benchmark metric.
