Intel Arc B370 vs NVIDIA GeForce RTX 5070 Ti SUPER Comparison

Intel Arc B370 is an integrated graphics processor built into Intel’s Panther Lake mobile platform, using the Xe3-LPG architecture on Intel’s 3 nm process. NVIDIA GeForce RTX 5070 Ti SUPER is a discrete add-in board based on the GB203 chip, Blackwell 2.0 architecture, fabricated by TSMC on a 5 nm node. The database contains a single DirectX 12 benchmark for both products, 3DMark Steel Nomad, where the NVIDIA part scores 6269.5 and the Intel part scores 1184. That represents an 81.1% deficit for the Intel solution, and the NVIDIA board wins the only recorded head-to-head test. This analysis covers what each product does well, architectural differences, and how the recorded data separates them.

Where Each One Wins

The Intel Arc B370 wins in the category of power efficiency and physical integration. Its thermal design power is 25 W, and it is classified as an IGP with no slot width, no power connectors, and a bus interface of IGP. This means it requires no separate power delivery, no expansion slot, and no dedicated cooler mounting. The NVIDIA GeForce RTX 5070 Ti SUPER, by contrast, carries a 350 W TDP, demands a dual-slot cooler, uses a single 16-pin power connector, and occupies a PCIe 5.0 x16 slot. For systems where space, cooling, and power draw are constrained, the Intel part is the only one of the two that can operate inside a compact mobile platform without external power.

The NVIDIA GeForce RTX 5070 Ti SUPER wins in every recorded performance metric. Its 3DMark Steel Nomad score of 6269.5 places it at the 36th percentile among all GPUs in the database, while the Intel Arc B370 sits at the 5th percentile. The nearest rivals for the NVIDIA part are the NVIDIA GeForce RTX 4070 Ti SUPER AD102 at 6270 (0% delta), the NVIDIA Quadro K620 at 6282 (-0.2%), the AMD FirePro W600 at 6223 (0.8%), and the AMD Radeon R7 M350 at 6327 (-0.9%). These clustered scores indicate that the RTX 5070 Ti SUPER performs essentially at parity with the RTX 4070 Ti SUPER AD102 in this test, while the other nearby entries are older workstation or low-end mobile parts that happen to land in the same score band. The Intel Arc B370’s nearest rivals are the ATI Mobility Radeon HD 5570 at 1186 (-0.2%), ATI Radeon HD 5770 at 1190 (-0.5%), AMD Radeon HD 7650M at 1192 (-0.7%), and AMD FirePro M2000 at 1168 (1.4%). The Intel part is effectively bracketed by a set of legacy GPUs from the early 2010s, which shows its performance class is far below modern discrete graphics.

The NVIDIA part also wins in raw throughput categories. Its FP32 compute is 43.94 TFLOPS versus 6.144 TFLOPS for the Intel part. Pixel fill rate is 235.4 GPixel/s versus 48.00 GPixel/s. Texture fill rate is 686.6 GTexel/s versus 96.00 GTexel/s. Memory bandwidth is 896.0 GB/s from 16 GB of GDDR7 on a 256-bit bus, while the Intel part uses system shared memory with bandwidth dependent on the host system. The NVIDIA board has 8960 shading units, 280 TMUs, 96 ROPs, 70 RT cores, and 280 tensor cores. The Intel part has 1280 shading units, 40 TMUs, 20 ROPs, and 10 RT cores, with no tensor core count listed.

Architecture Differences

The Intel Arc B370 uses the Xe3-LPG architecture, which is the low-power graphics variant of Intel’s third-generation Xe design. It is manufactured on Intel’s own 3 nm process and is integrated into the Panther Lake processor. The chip’s base clock is 300 MHz and boost clock is 2400 MHz. Memory is entirely system shared, meaning there is no dedicated VRAM, no dedicated memory bus width, and no fixed bandwidth figure; the database lists bandwidth as system dependent. The GPU supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Display outputs are listed as portable device dependent, which fits its IGP classification.

The NVIDIA GeForce RTX 5070 Ti SUPER uses the Blackwell 2.0 architecture on the GB203 die. The chip contains 45,600 million transistors on a 378 mm² die, giving a transistor density of 120.6 million per square millimeter. It is built on TSMC’s 5 nm process. Base clock is 2295 MHz, boost clock is 2452 MHz, and memory runs at 1750 MHz with 28 Gbps effective data rate. The memory subsystem is 16 GB of GDDR7 on a 256-bit bus, delivering 896.0 GB/s of bandwidth. The graphics card includes 8960 shading units, 280 TMUs, 96 ROPs, 70 RT cores, and 280 tensor cores. FP16 performance is 43.94 TFLOPS at a 1:1 ratio with FP32, whereas the Intel part reaches 12.29 TFLOPS FP16 at a 2:1 ratio. The NVIDIA card has a dual-slot cooler, measures 304 mm in length, 137 mm in height, and 48 mm in width, and uses a single 16-pin power connector. Display outputs are 1x HDMI 2.1b and 3x DisplayPort 2.1b.

The process node difference is notable. Intel uses a 3 nm node, which is smaller than the 5 nm node used by NVIDIA, yet the NVIDIA part achieves dramatically higher performance because it deploys far more hardware resources. The Intel part’s 1280 shading units and 10 RT cores are a fraction of the NVIDIA part’s 8960 shading units and 70 RT cores. The transistor count for the Intel chip is unknown in the database, so a direct transistor comparison is not possible. The die size is also unknown for the Intel part. The NVIDIA die is 378 mm² and integrates 45,600 million transistors.

Both products support the same API versions: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. That means feature-level API support is identical, even though execution resources differ by an order of magnitude. The RTX 5070 Ti SUPER has tensor cores listed at 280, while the Intel part has no tensor core entry in the database. FP16 throughput on the Intel part is listed as 12.29 TFLOPS (2:1), meaning it halves rate for FP32 work, while the NVIDIA part delivers 43.94 TFLOPS at a 1:1 ratio, meaning FP16 and FP32 rates are equal.

Power delivery separates the two sharply. The Intel Arc B370 is a 25 W IGP with no power connectors and no suggested PSU. The NVIDIA GeForce RTX 5070 Ti SUPER is a 350 W dual-slot card with a 16-pin connector. Clock behavior also differs: the Intel part runs at a low 300 MHz base with a 2400 MHz boost, a wide span that allows it to idle very low and ramp when needed. The NVIDIA part runs at 2295 MHz base and 2452 MHz boost, a much narrower range, because it is designed to sustain high clocks under load with active cooling.

The Verdict

The recorded data indicates that these two products serve entirely different roles. The Intel Arc B370 is an integrated GPU for a mobile processor, drawing 25 W, using system shared memory, and producing a 3DMark Steel Nomad score of 1184. Its nearest rivals are legacy parts like the ATI Radeon HD 5770 and AMD Radeon HD 7650M, which places it in the performance class of decade-old discrete GPUs. The NVIDIA GeForce RTX 5070 Ti SUPER is a high-end discrete card with a 350 W TDP, 16 GB of GDDR7, and a Steel Nomad score of 6269.5, which is 81.1% higher than the Intel part. Its nearest rival is the RTX 4070 Ti SUPER AD102 at a 0% delta, meaning the two perform identically in this benchmark.

For any workload that requires 3D rendering performance, the database shows the NVIDIA part is the only viable option. The 6.144 TFLOPS FP32 of the Intel part versus 43.94 TFLOPS for the NVIDIA part, combined with the 896.0 GB/s memory bandwidth versus system dependent shared memory, confirms that the NVIDIA card is in a different performance tier. The Intel part is not positioned as a competitor to the RTX 5070 Ti SUPER; its 5th percentile ranking versus the NVIDIA part’s 36th percentile ranking places them far apart in the overall GPU distribution.

Users of a thin-and-light mobile system with no discrete graphics slot would be limited to the Intel Arc B370. Users building a desktop with a PCIe 5.0 x16 slot, a 350 W power budget, and a dual-slot cooler can use the RTX 5070 Ti SUPER. The data does not support any scenario where the Intel part wins a performance comparison. The only wins for the Intel part are in power draw, physical footprint, and lack of external power requirements. The NVIDIA part wins the only recorded head-to-head benchmark, and it wins by a margin that makes the comparison one-sided.

Head-to-Head Benchmarks

The only recorded head-to-head benchmark is 3DMark Steel Nomad under DirectX 12. The NVIDIA GeForce RTX 5070 Ti SUPER scores 6269.5, and the Intel Arc B370 scores 1184. The delta is -81.1% for the Intel part, meaning the NVIDIA card delivers roughly five times the score. In the database’s benchmark list, the NVIDIA part’s average benchmark score is 6270, and the Intel part’s is 1184.

Beyond the single head-to-head test, the recorded specifications show the scale of the gap. The NVIDIA card’s FP32 throughput is 43.94 TFLOPS, which is about seven times the Intel part’s 6.144 TFLOPS. Pixel rate is 235.4 GPixel/s versus 48.00 GPixel/s, about 4.9 times higher. Texture rate is 686.6 GTexel/s versus 96.00 GTexel/s, about 7.2 times higher. The NVIDIA card has 70 RT cores versus 10, and 280 tensor cores versus none listed for the Intel part. Memory bandwidth is 896.0 GB/s versus system dependent, and the NVIDIA card has a fixed 16 GB GDDR7 pool while the Intel part shares system RAM.

Clock speeds tell a different efficiency story. The Intel part’s base clock is 300 MHz and boost is 2400 MHz, so it can drop very low when idle and still reach a competitive boost for an IGP. The NVIDIA card runs at 2295 MHz base and 2452 MHz boost, meaning its minimum operating clock is already near the Intel part’s maximum boost. Yet the NVIDIA card consumes 350 W versus 25 W. That 14x power difference buys roughly a 5x performance difference in the recorded benchmark, which is an expected trade-off for a discrete high-end GPU versus an integrated low-power GPU.

The NVIDIA part’s nearest rival data shows it sits at 6270 average score, exactly matching the RTX 4070 Ti SUPER AD102 at 6270 with a 0% delta. The Quadro K620 at 6282 is -0.2% relative to the RTX 5070 Ti SUPER, and the AMD Radeon R7 M350 at 6327 is -0.9%. This cluster indicates that the RTX 5070 Ti SUPER is not an outlier; it performs within 1% of several other GPUs in the database. The Intel part’s nearest rivals, by contrast, are all older parts: ATI Mobility Radeon HD 5570 at 1186, ATI Radeon HD 5770 at 1190, AMD Radeon HD 7650M at 1192, and AMD FirePro M2000 at 1168. The Intel part’s 1184 score falls between the FirePro M2000 and the Mobility Radeon HD 5570, with deltas ranging from -0.7% to 1.4%.

Physical specifications reinforce the performance divide. The NVIDIA card is 304 mm long, 137 mm tall, and 48 mm wide, requiring a full-size desktop chassis. The Intel part has no listed dimensions because it is an IGP. The NVIDIA card uses a PCIe 5.0 x16 interface; the Intel part uses an IGP bus interface. The NVIDIA card has 1x HDMI 2.1b and 3x DisplayPort 2.1b outputs; the Intel part’s display outputs are portable device dependent.

Process technology favors Intel in lithography: 3 nm versus 5 nm. But the NVIDIA part compensates with a 378 mm² die containing 45,600 million transistors, while the Intel die size and transistor count are unknown. The transistor density of the NVIDIA die is 120.6 million per square millimeter. No density figure exists for the Intel part. The NVIDIA part’s FP16 rate equals its FP32 rate at 43.94 TFLOPS, while the Intel part’s FP16 rate is 12.29 TFLOPS at a 2:1 ratio, meaning it is half the FP32 rate. The NVIDIA part’s 280 tensor cores are absent from the Intel specification entirely.

The data confirms that the NVIDIA GeForce RTX 5070 Ti SUPER is the faster product by every measurable performance metric. The Intel Arc B370 is the lower-power, integrated alternative with a much smaller footprint. The recorded benchmark, the percentile rankings, and the nearest rival comparisons all point in the same direction: a 5th percentile IGP versus a 36th percentile discrete card, with an 81.1% delta in the only direct test.
