NVIDIA GeForce RTX 2080 SUPER vs NVIDIA GeForce RTX 3080 Ti Mobile Comparison

# Head-to-Head Benchmarks

The most striking result in this comparison is the 3DMark Steel Nomad DX12 test, where the RTX 3080 Ti Mobile delivers a score of 2869 against the RTX 2080 SUPER's 1882. That is a 52.4% advantage for the mobile part, a margin so large that it reshapes expectations about what a laptop GPU can achieve against a desktop card from the previous generation. The gap suggests that Ampere's architectural efficiency, combined with the 3080 Ti Mobile's much larger shading unit count, translates directly into raw DX12 throughput that the older Turing part simply cannot match.

The Geekbench OpenCL result tells a similar story, though with a smaller margin. The 3080 Ti Mobile scores 117866, while the 2080 SUPER manages 99226, a difference of 18.8%. This is a substantial lead in a compute-oriented workload that exercises the GPU's general-purpose capabilities rather than just rasterization. The pattern continues in Passmark DirectX 12, where the 3080 Ti Mobile wins 88 to 75, a 17.3% edge. DX12 is the modern API standard, and the newer architecture's advantage here is consistent with its Steel Nomad result.

The compute picture is closer but still favors the mobile part. Passmark GPU Compute shows 8471 for the 3080 Ti Mobile versus 8290 for the 2080 SUPER, a modest 2.2% lead. Given that the 3080 Ti Mobile has 7424 shading units against the 2080 SUPER's 3072, the compute margin seems surprisingly small. This could indicate that the 2080 SUPER's higher clock speeds — 1815 MHz boost versus 1260 MHz — are partially compensating for its lower core count in certain workloads, or that the mobile part is power-limited in sustained compute tasks.

The 2080 SUPER fights back in several legacy and synthetic tests. In Geekbench Vulkan, it scores 111284 to the 3080 Ti Mobile's 107502, a 3.4% reversal. Vulkan is a low-overhead API, and the 2080 SUPER's higher base clock of 1650 MHz may give it an edge in latency-sensitive draw call scenarios. The older card also wins Passmark DirectX 10 (140 vs 131, a 6.4% gap), DirectX 9 (227 vs 201, an 11.5% margin), and DirectX 11 (165 vs 164, a razor-thin 0.6% lead). These legacy DX9 and DX10 results are particularly interesting — the 2080 SUPER's advantage suggests that older APIs may not fully utilize the 3080 Ti Mobile's additional cores, or that driver optimizations for the newer architecture prioritize modern workloads.

The 2D test also goes to the 2080 SUPER, with 920 versus 818, an 11.1% difference. This is not a gaming metric but rather a measure of desktop composition and video playback performance, and the older card's win here is notable. Finally, Passmark G3D shows a near-tie: 19490 for the 2080 SUPER against 19288 for the 3080 Ti Mobile, a 1% edge for the desktop card. This aggregate DirectX gaming score suggests that in mixed API workloads, the two GPUs are effectively equivalent, despite the 3080 Ti Mobile's overwhelming DX12 performance.

# The Verdict

The data tells a story of generational divergence rather than a simple winner. The RTX 3080 Ti Mobile wins 4 of the 10 head-to-head benchmarks, but its victories are concentrated in the most modern and compute-heavy tests. The 52.4% lead in 3DMark Steel Nomad DX12 and the 18.8% lead in Geekbench OpenCL are the headline numbers — these are the workloads that will matter for future games and GPU-accelerated applications. Meanwhile, the 2080 SUPER wins 6 tests, but many of those wins are in legacy APIs (DX9, DX10) or in tests where the margin is tiny (0.6% in DX11, 1% in G3D).

Benchmark results indicate that the 3080 Ti Mobile is the better choice for forward-looking gaming and compute. Its average benchmark score of 25740 versus 24170 for the 2080 SUPER represents a 6.5% overall advantage, and it sits at the 71st percentile of all GPUs compared to the 2080 SUPER's 69th. The 3080 Ti Mobile's nearest rivals are the AMD Radeon Pro W5700 (0.1% ahead), AMD FirePro D700 (0.4% behind), and AMD Radeon RX 6700M (0.4% behind) — a tight cluster. The 2080 SUPER, by contrast, is closest to the NVIDIA GeForce GTX 780 Ti (0.3% behind) and GTX 1630 (0.4% behind), which are far older parts. This clustering suggests the 2080 SUPER is not just competing with its contemporaries but is being compared against much older hardware in the database, reinforcing its status as a dated, though still capable, desktop card.

For gamers who play modern DX12 titles, the 3080 Ti Mobile is the clear pick. For users running legacy applications or who prioritize Vulkan performance, the 2080 SUPER holds its ground. The 3080 Ti Mobile's 16 GB of memory versus 8 GB on the 2080 SUPER also matters for texture-heavy workloads, though the benchmark data does not directly measure VRAM capacity effects.

# Architecture Differences

The two GPUs represent different architectural generations from NVIDIA. The RTX 3080 Ti Mobile uses the GA103 chip based on the Ampere architecture, fabricated on Samsung's 8 nm process. The RTX 2080 SUPER uses the TU104 chip based on the older Turing architecture, built on TSMC's 12 nm process. This process difference is significant: the 8 nm node allows for a much higher transistor density of 44.4 million transistors per square millimeter, compared to 25.0 million on the 12 nm node. The Ampere chip packs 22,000 million transistors into a 496 mm² die, while the Turing chip contains 13,600 million transistors on a larger 545 mm² die.

The core configuration differs dramatically. The 3080 Ti Mobile has 7424 shading units, 232 TMUs, and 96 ROPs, along with 58 ray tracing cores and 232 tensor cores. The 2080 SUPER has 3072 shading units, 192 TMUs, and 64 ROPs, with 48 ray tracing cores and 384 tensor cores. The 3080 Ti Mobile has more than double the shading units and significantly more ROPs, but the 2080 SUPER has more tensor cores. This tensor core count difference is curious — the Ampere part has fewer tensor cores but they are likely more efficient per core, though the benchmark data does not directly measure tensor performance.

The memory subsystem also diverges. Both use GDDR6 memory on a 256-bit bus, but the 3080 Ti Mobile offers 16 GB at a bandwidth of 512.0 GB/s, while the 2080 SUPER has 8 GB at 495.9 GB/s. The mobile part's memory runs at 2000 MHz (16 Gbps effective), while the desktop card runs at 1937 MHz (15.5 Gbps effective). The 3.2% bandwidth advantage for the 3080 Ti Mobile is modest, but the doubling of VRAM capacity is a major architectural difference that could affect performance in memory-intensive scenarios.

API support is identical — both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The bus interface differs, with the 3080 Ti Mobile using PCIe 4.0 x16 and the 2080 SUPER using PCIe 3.0 x16. The newer PCIe standard offers more bandwidth for data transfer, though the practical impact depends on the workload.

# Specification Differences

The clock speeds are a major differentiator. The 2080 SUPER runs at a 1650 MHz base and 1815 MHz boost, while the 3080 Ti Mobile runs at 810 MHz base and 1260 MHz boost. The desktop card's clocks are significantly higher, which helps explain its competitive performance despite having fewer cores. The 3080 Ti Mobile's FP32 throughput is 18.71 TFLOPS, well above the 2080 SUPER's 11.15 TFLOPS. However, in FP16, the 2080 SUPER achieves 22.30 TFLOPS at a 2:1 ratio, while the 3080 Ti Mobile matches its FP32 at 18.71 TFLOPS (1:1). This means the older card has higher raw FP16 throughput, which could matter for certain AI workloads.

Power consumption is another major difference. The 3080 Ti Mobile has a TDP of 115 W, while the 2080 SUPER draws 250 W. The mobile part achieves its performance at less than half the power draw, proof of the efficiency gains of the newer architecture. The 2080 SUPER requires a 600 W power supply and uses 1x 6-pin plus 1x 8-pin power connectors, while the 3080 Ti Mobile uses no external power connectors, relying on the laptop's power delivery system. The desktop card is a dual-slot design measuring 267 mm in length, 116 mm in height, and 35 mm in width, while the mobile part has dimensions that are portable device dependent.

The 2080 SUPER offers 1x HDMI 2.0, 3x DisplayPort 1.4a, and 1x USB Type-C outputs, while the 3080 Ti Mobile's display outputs are portable device dependent. The desktop card has a launch MSRP of 699 USD, while the mobile part has no listed launch MSRP. The 2080 SUPER was released on 2019-07-22 and predates the 3080 Ti Mobile's release on 2022-01-24. The 2080 SUPER's successor is the GeForce 30 series, which includes the 3080 Ti Mobile, while the 3080 Ti Mobile has no successor listed.

# Where Each One Wins

The RTX 3080 Ti Mobile is the clear winner in modern DX12 gaming. Its 52.4% lead in 3DMark Steel Nomad DX12 and 17.3% lead in Passmark DirectX 12 indicate that games built around the latest API will run substantially better on the Ampere part. The 18.8% advantage in Geekbench OpenCL also makes it the better choice for GPU compute tasks like machine learning inference, video encoding, and scientific simulations that leverage OpenCL. The 2.2% win in Passmark GPU Compute, while modest, confirms the trend in compute-heavy workloads. With 16 GB of VRAM, the 3080 Ti Mobile is also better positioned for future games that require large texture datasets, even though the benchmark data does not directly measure this.

The RTX 2080 SUPER holds advantages in legacy API performance. Its 11.5% win in Passmark DirectX 9 and 6.4% win in DirectX 10 suggest that older games, particularly those from the DirectX 9 and 10 era, will run at least as well on the Turing card, if not better. The 3.4% lead in Geekbench Vulkan indicates that Vulkan-based titles may prefer the 2080 SUPER's higher clock speeds. The 11.1% win in Passmark G2D is relevant for users who spend significant time in desktop applications or 2D workloads. The 1% edge in Passmark G3D, while tiny, means that in a mixed bag of DirectX gaming tests, the 2080 SUPER is marginally ahead.

The power envelope is a critical factor. The 3080 Ti Mobile's 115 W TDP makes it suitable for laptops, while the 2080 SUPER's 250 W TDP and 600 W suggested PSU mean it requires a desktop power supply and cooling solution. For users building a desktop system, the 2080 SUPER's higher clocks and legacy API wins might be appealing, but the 3080 Ti Mobile's efficiency and modern architecture make it the more future-proof option. The 2080 SUPER's closest rivals in the database are the GTX 780 Ti and GTX 1630, both much older parts, which highlights its aging position. The 3080 Ti Mobile, by contrast, clusters with AMD's Radeon RX 6700M and Pro W5700, placing it in more modern company.
