Q: What is the performance percentile ranking for each?

A: The RTX 5070 Ti ranks in the 86th percentile among all GPUs with an average benchmark score of 49,957. The N1X 48SM ranks in the 50th percentile with an average benchmark score of 0 due to having no recorded benchmarks.

Architecture Differences

The two GPUs share the Blackwell 2.0 architecture and TSMC 5 nm process node, but diverge sharply in implementation. The RTX 5070 Ti uses the GB203 chip with 45,600 million transistors on a 378 mm² die, giving a transistor density of 120.6M per mm². The N1X 48SM uses the GB20B chip on a 382 mm² die with unknown transistor count and density. Both are active production parts, but the N1X 48SM is classified as an IGP (integrated graphics processor) with a slot width of "IGP" and no power connectors, while the RTX 5070 Ti is a dual-slot discrete card using a single 16-pin connector.

The shading unit counts differ substantially: 8,960 on the RTX 5070 Ti versus 6,144 on the N1X 48SM. However, the N1X 48SM has more texture mapping units at 384 versus 280, which gives it a higher texture rate of 900.9 GTexel/s compared to 686.6 GTexel/s on the RTX 5070 Ti. The RTX 5070 Ti has double the ROPs at 96 versus 48, and its pixel rate of 235.4 GPixel/s far exceeds the N1X 48SM's 112.6 GPixel/s.

RT and tensor core counts favor the RTX 5070 Ti: 70 RT cores and 280 tensor cores versus 48 RT cores and 192 tensor cores on the N1X 48SM. Clock behavior also differs, with the RTX 5070 Ti running a 2295 MHz base and 2452 MHz boost, while the N1X 48SM has a much lower 741 MHz base but a 2346 MHz boost, indicating a wider dynamic range.

Memory architecture is a major differentiator. The RTX 5070 Ti uses 16 GB of GDDR7 at 1750 MHz (28 Gbps effective) for 896.0 GB/s bandwidth. The N1X 48SM uses 128 GB of LPDDR5X at 1067 MHz (8.5 Gbps effective) for only 273.2 GB/s. Both use a 256-bit bus, but the memory type and capacity create entirely different use profiles.

API support further separates them. The RTX 5070 Ti lists DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1X 48SM records N/A for all three APIs, which aligns with its IGP classification and lack of benchmark data.

Head-to-Head Benchmarks

The head-to-head benchmark table between these two GPUs is empty, meaning no direct comparative tests have been recorded. However, the RTX 5070 Ti has ten individual benchmark scores in the database, while the N1X 48SM has none. This absence of data for the N1X 48SM is itself informative: it ranks at the 50th percentile with an average score of 0, meaning the database has no measured performance to report.

The RTX 5070 Ti's benchmark results show a strong profile. In 3DMark Steel Nomad DX12, it scores 6,604. Geekbench OpenCL gives 212,363, and Geekbench Vulkan gives 225,122. Passmark results include 32,974 in G3D, 20,203 in GPU Compute, 1,332 in G2D, and lower scores in legacy DirectX tests: 351 in DX9, 300 in DX11, 192 in DX10, and 127 in DX12.

Comparing the RTX 5070 Ti to its nearest rivals in the database provides context. Its average benchmark score of 49,957 sits 0.1% below the AMD Radeon RX Vega 64 (50,001), 0.4% above the Intel Arc A550M (49,737), 2% below the AMD Radeon RX 6900 XT (50,951), and 3.1% above the AMD Radeon RX 6800 XT (48,477). These deltas show the RTX 5070 Ti clustering tightly with high-end previous-generation cards, within a 5% band overall.

Since the N1X 48SM has no benchmark scores, no direct percentage comparisons can be made. The data indicates that the RTX 5070 Ti is a fully characterized discrete GPU, while the N1X 48SM remains unmeasured in the database despite being an active product.

The Verdict

The recorded data makes a clear distinction between these two products. The RTX 5070 Ti is a complete, benchmarked discrete GPU with an 86th percentile ranking, a 49,957 average score, and ten individual test results. The N1X 48SM is an active IGP with no benchmarks, a 50th percentile ranking, and an average score of zero.

For any workload requiring measured graphics performance, the RTX 5070 Ti is the only option with supporting data. Its 43.94 TFLOPS FP32 throughput, 896.0 GB/s memory bandwidth, and 70 RT cores position it as a high-end rendering solution. The N1X 48SM's 28.83 TFLOPS and 273.2 GB/s bandwidth are lower in every compute metric except texture rate, where its 384 TMUs give it an advantage.

The N1X 48SM's 128 GB of LPDDR5X memory is its standout feature, but the low bandwidth of 273.2 GB/s suggests it serves a different purpose, likely integrated system memory rather than dedicated graphics memory. Its IGP classification, lack of power connectors, and N/A API support reinforce this interpretation.

The RTX 5070 Ti lists a launch MSRP of 749 USD. The N1X 48SM has no launch MSRP recorded. The RTX 5070 Ti requires a 700 W suggested PSU, while the N1X 48SM has no PSU requirement listed.

Where Each One Wins

The RTX 5070 Ti wins decisively in raw compute and rendering throughput. Its FP32 of 43.94 TFLOPS is 52% higher than the N1X 48SM's 28.83 TFLOPS. Pixel rate favors the RTX 5070 Ti at 235.4 GPixel/s versus 112.6 GPixel/s, more than double. Memory bandwidth is 896.0 GB/s versus 273.2 GB/s, a 3.3x advantage. The RTX 5070 Ti also has more RT cores (70 vs 48), more tensor cores (280 vs 192), and more shading units (8,960 vs 6,144). Its 96 ROPs versus 48 further widens the gap in fill-rate-bound scenarios.

The N1X 48SM wins in texture throughput. Its 384 TMUs produce 900.9 GTexel/s compared to 686.6 GTexel/s on the RTX 5070 Ti, a 31% advantage. This means the N1X 48SM can process texture-heavy workloads faster per unit time, assuming the rest of the pipeline can keep up. The N1X 48SM also offers 128 GB of memory versus 16 GB, which is an 8x capacity advantage, though at much lower bandwidth.

For use-case separation, the RTX 5070 Ti suits discrete gaming and rendering workloads where its high bandwidth, strong pixel throughput, and full API support matter. Its 70 RT cores and 280 tensor cores make it appropriate for ray-traced and AI-accelerated tasks. The N1X 48SM, as an IGP with 128 GB of shared memory, targets integrated system scenarios where large memory capacity is more important than raw speed. Its lack of API support and absence of benchmark data mean it cannot be recommended for standard graphics API workloads based on the recorded information.

The RTX 5070 Ti's 86th percentile ranking and average score of 49,957 place it among the top tier of tested GPUs. The N1X 48SM's 50th percentile with a zero score reflects its unmeasured status rather than any known performance level. In any comparison requiring benchmark evidence, the RTX 5070 Ti is the only card with data to support its position.
