Intel Arc B580 vs NVIDIA GeForce GTX TITAN Z Comparison

# Head-to-Head Benchmarks

The benchmark data presents an unambiguous picture when comparing the NVIDIA GeForce GTX TITAN Z against the Intel Arc B580. Across the two shared benchmark tests, the Intel Arc B580 secures a decisive victory in both instances, leaving the GTX TITAN Z without a single winning result.

In the Geekbench OpenCL test, the Intel Arc B580 scores 92,821, while the NVIDIA GeForce GTX TITAN Z manages 25,465. This represents a deltaPct of -72.6% relative to the Intel card, meaning the Intel Arc B580 outperforms the GTX TITAN Z by a massive margin. To put this in perspective, the GTX TITAN Z's score places it at only 27.4% of the Intel Arc B580's performance in this compute-oriented workload. The magnitude of this gap is striking — the Intel GPU delivers more than 3.6 times the raw compute performance in OpenCL.

The Vulkan benchmark tells an even more pronounced story. The Intel Arc B580 posts a score of 109,672, whereas the GTX TITAN Z trails far behind at 22,006. The deltaPct here is -79.9%, indicating that the Intel GPU is nearly five times faster in this API. This is not a marginal difference; it is a generational chasm. The GTX TITAN Z's Vulkan score represents only about 20% of what the Intel Arc B580 achieves, suggesting that the older NVIDIA architecture struggles significantly with modern graphics APIs.

Looking at the broader context, the GTX TITAN Z's average benchmark score across all tests is 23,736, while the Intel Arc B580 averages 23,021. Despite the Intel card winning both head-to-head tests decisively, the average scores are remarkably close — the GTX TITAN Z is actually 3.1% higher in average score. This seeming contradiction stems from the fact that the Intel Arc B580 has many more benchmark entries, including several Passmark tests where it scores relatively low (for example, 76 in DirectX 10 and 76 in DirectX 12, but 183 in DirectX 9 and 15748 in 3D Mark graphics).

The percentile rankings are nearly identical: the GTX TITAN Z sits at the 69th percentile among all GPUs, while the Intel Arc B580 is at the 68th percentile. This closeness in overall standing, contrasted with the lopsided head-to-head results, suggests that the two cards occupy similar tiers in the broader GPU landscape, but their strengths are distributed very differently across workload types.

# The Verdict

From the data, the choice between these two GPUs depends heavily on the intended use case and the software environment. For anyone running modern workloads that leverage Vulkan or OpenCL — which includes most contemporary games, creative applications, and compute tasks — the Intel Arc B580 is the clear winner. Its Vulkan score of 109,672 versus the GTX TITAN Z's 22,006 represents a 79.9% advantage, and its OpenCL score of 92,821 versus 25,465 is a 72.6% advantage. These are not close calls; the Intel GPU dominates in both shared tests.

The GTX TITAN Z, despite its age, still holds a slight edge in average benchmark score (23,736 vs 23,021), which is a 3.1% difference. This is largely attributable to the fact that the NVIDIA card's benchmark suite is limited to Geekbench tests, where it performs consistently. The Intel Arc B580, by contrast, has a broader benchmark portfolio that includes Passmark tests where its performance is uneven — strong in G3D (15,748) and GPU compute (7,729), but weak in DirectX 10 and 12 (both 76) and DirectX 11 (128).

For a buyer selecting between these two today, the Intel Arc B580 is the rational choice for nearly any modern scenario. The Vulkan and OpenCL results indicate that it handles contemporary APIs with far greater efficiency. The GTX TITAN Z's only conceivable advantage would be in legacy DirectX workloads, but the data does not include any DirectX benchmark results for the NVIDIA card, so that advantage cannot be substantiated from the available information.

The production status reinforces this verdict: the GTX TITAN Z is end-of-life, while the Intel Arc B580 is active and currently produced. The Intel card also carries a launch MSRP of 249 USD, while the GTX TITAN Z launched at 2,999 USD — though price differences are noted here only as factual data points, not as a value assessment.

# Architecture Differences

The architectural divide between these two GPUs is substantial, reflecting their ten-year separation in release dates. The NVIDIA GeForce GTX TITAN Z is built on the Kepler architecture, specifically the GK110B chip, and belongs to the GeForce 700 generation. It uses a 28 nm process node fabricated by TSMC, with a transistor count of 7,080 million spread across a die size of 561 mm². This yields a transistor density of 12.6 million transistors per square millimeter — a figure that now seems modest by modern standards.

The Intel Arc B580, in contrast, employs the Xe2-HPG architecture on the BMG-G21 chip, part of the Battlemage (Arc 5) generation. It is manufactured on a 5 nm process node, also by TSMC, and packs 19,600 million transistors into a considerably smaller die of 272 mm². The transistor density of 72.1 million per square millimeter is nearly six times higher than the Kepler chip, illustrating the immense fabrication advances over the decade separating these products.

The GTX TITAN Z has no ray tracing cores and no tensor cores, as those technologies did not exist in NVIDIA's lineup at that time. The Intel Arc B580, meanwhile, includes 20 ray tracing cores, enabling hardware-accelerated ray tracing that the Kepler GPU cannot perform. The Intel card also supports DirectX 12 Ultimate (12_2), whereas the GTX TITAN Z is limited to DirectX 12 (11_1) — a critical distinction for modern game compatibility.

Vulkan support also differs: the Intel Arc B580 supports Vulkan 1.4, while the GTX TITAN Z is limited to Vulkan 1.2.175. Both cards support OpenGL 4.6. The memory technologies are generations apart as well — GDDR5 for NVIDIA versus GDDR6 for Intel — and the interface speeds reflect this: the GTX TITAN Z's memory runs at 1750 MHz (7 Gbps effective), while the Intel Arc B580's memory runs at 2375 MHz (19 Gbps effective).

# Specification Differences

The specification sheets for these two GPUs reveal stark contrasts across nearly every measurable parameter. The NVIDIA GeForce GTX TITAN Z offers 6 GB of GDDR5 memory on a 384-bit bus, delivering 336.0 GB/s of bandwidth. The Intel Arc B580 doubles the capacity to 12 GB of GDDR6, though on a narrower 192-bit bus, yet achieves significantly higher bandwidth at 456.0 GB/s — a 35.7% improvement.

Shading unit counts are comparable in raw numbers: the GTX TITAN Z has 2,880 shading units, while the Intel Arc B580 has 2,560 — a difference of 11.1% in favor of the NVIDIA card. However, the texture mapping units (TMUs) tell a different story: NVIDIA has 240 TMUs versus Intel's 160, a 50% advantage for the older card. The render output units (ROPs) reverse this: NVIDIA has 48 ROPs versus Intel's 80, giving the Intel GPU a 66.7% advantage in pixel processing.

Clock speeds are dramatically different. The GTX TITAN Z runs at a base clock of 705 MHz with a boost of 876 MHz. The Intel Arc B580 operates at a flat 2670 MHz for both base and boost — more than three times the NVIDIA card's base clock. This frequency advantage translates directly into throughput figures: the Intel card achieves 213.6 GPixel/s pixel rate versus 52.56 GPixel/s for NVIDIA (a 306% difference), and 427.2 GTexel/s texture rate versus 210.2 GTexel/s (a 103% difference). The FP32 compute performance is 13.67 TFLOPS for Intel versus 5.046 TFLOPS for NVIDIA, a 171% advantage. The Intel card also lists FP16 performance at 27.34 TFLOPS (2:1), a capability the NVIDIA card does not specify.

Power and physical specifications differ just as markedly. The GTX TITAN Z has a TDP of 375 W, requires a 750 W suggested PSU, uses two 8-pin power connectors, and occupies a triple-slot width. The Intel Arc B580 draws 190 W, needs a 450 W PSU, uses a single 8-pin connector, and fits in a dual-slot design. The NVIDIA card measures 267 mm in length, 111 mm in height, and 62 mm in width; the Intel card is slightly longer at 272 mm, taller at 115 mm, but much thinner at 45 mm.

The bus interface also differs: the GTX TITAN Z uses PCIe 3.0 x16, while the Intel Arc B580 uses PCIe 4.0 x8. Display outputs vary as well — the NVIDIA card offers 2x DVI, 1x HDMI 1.4a, and 1x DisplayPort 1.2, whereas the Intel card provides 1x HDMI 2.1a and 3x DisplayPort 2.1.

# Where Each One Wins

The Intel Arc B580 dominates in every head-to-head benchmark category available, making it the unequivocal winner for modern compute and graphics workloads. Its Geekbench OpenCL score of 92,821 versus 25,465 and Vulkan score of 109,672 versus 22,006 demonstrate that it handles contemporary APIs with far greater efficiency. The 5 nm process node, 19,600 million transistors, and 2670 MHz clock speed all contribute to this superiority. The Intel card also wins on memory bandwidth (456.0 GB/s vs 336.0 GB/s), pixel rate (213.6 GPixel/s vs 52.56 GPixel/s), texture rate (427.2 GTexel/s vs 210.2 GTexel/s), and FP32 compute (13.67 TFLOPS vs 5.046 TFLOPS). Its 20 ray tracing cores provide a capability the NVIDIA card entirely lacks, and its DirectX 12 Ultimate support ensures compatibility with the latest games.

The NVIDIA GeForce GTX TITAN Z, despite its age, retains a few narrow advantages from the data. Its average benchmark score of 23,736 edges out the Intel card's 23,021. It has more shading units (2,880 vs 2,560) and more texture mapping units (240 vs 160). The 384-bit memory bus is wider than Intel's 192-bit bus, and the GTX TITAN Z's 48 ROPs, while fewer than Intel's 80, still represent a functional pixel pipeline. However, none of these advantages translate into a win in any shared benchmark test. The GTX TITAN Z's higher average score appears to be an artifact of its limited benchmark suite rather than genuine superiority.

For use-case selection, the data points to the Intel Arc B580 for virtually any modern application. Gamers, content creators, and compute professionals working with Vulkan or OpenCL will see dramatically better performance. The Intel card's lower TDP of 190 W versus 375 W also makes it more practical for system integration. The GTX TITAN Z might still function in legacy DirectX 9 or 10 environments, but no benchmark data is available to confirm this, and its end-of-life status makes it a risky choice for future software compatibility. The Intel Arc B580 is the data-driven recommendation for essentially all scenarios.
