RTX 2080 Ti vs Arc B570: Which Graphics Card Should You Buy?

For most buyers, the Intel Arc B570 is the better choice: it comes close to the RTX 2080 Ti’s gaming performance as a new card with a warranty, uses about 100 W less power, and supports modern features like XeSS 2 frame generation. A used RTX 2080 Ti is still worth considering if it is cheap, if you have an older CPU or a motherboard without Resizable BAR, or if you want DLSS support across a large library of games.

These two cards sit seven years apart. The RTX 2080 Ti was Nvidia’s Turing flagship from September 2018, with a $999 launch price. The Arc B570 is Intel’s entry Battlemage card from January 2025, launched at $219. That a budget card now lands near a former flagship says a lot about how far GPUs have come, but the details decide which one makes sense for your build.

Spec Breakdown

The 2080 Ti’s wide 352-bit bus and 616 GB/s of bandwidth still look impressive, and it carries 1 GB more VRAM. The B570 compensates with far higher clocks, a newer architecture and more cache, at 60% of the power rating. The HDMI difference matters for some TV setups: HDMI 2.0 on the 2080 Ti tops out at 4K 60 Hz, while HDMI 2.1a on the B570 supports 4K 120 Hz on compatible TVs.

Head-to-Head Gaming Performance

Benchmark data places the RTX 2080 Ti slightly ahead overall. Aggregate comparisons such as HowManyFPS and DropReference put the 2080 Ti roughly 4-15% faster on average depending on the game mix and resolution. Some synthetic-heavy aggregates show a much larger gap, but those lean on older benchmarks and do not reflect current games well. Individual titles vary widely: PCBench’s game data shows the 2080 Ti ahead by double digits in games such as Horizon Forbidden West, while the B570 wins in others, such as Forza Horizon 5 at 1440p. For context, KitGuru’s review data places the B570 within a few percent of the RTX 4060.

A fair summary is that the 2080 Ti is roughly 5-15% faster in typical games, with plenty of exceptions in both directions. At 1080p high settings, both cards typically run demanding current games in roughly the 50-80 fps range; at 1440p, both generally need medium-high settings or upscaling for newer AAA titles. Figures vary with settings, CPU and game patches.

Ray Tracing: First-Gen RT vs Battlemage

The 2080 Ti was the first-generation ray tracing flagship, and its RT hardware is older than the B570’s. Battlemage’s ray tracing units are considerably more modern, and Intel cards generally perform well in RT for their class. In practice, the two land in similar territory in many ray-traced games, but neither is a strong ray tracing card by 2026 standards; expect to use upscaling and moderate RT settings on both.

Upscaling and Frame Generation Support

• RTX 2080 Ti: DLSS super resolution, including the DLSS 4 transformer model, which Nvidia made available back to RTX 20 cards. No DLSS frame generation, which requires RTX 40 or newer. It can use FSR frame generation in supported games.
• Arc B570: XeSS 2, including XeSS super resolution, XeSS frame generation and Xe Low Latency. It can also use FSR upscaling and frame generation.

DLSS upscaling is supported in more games than XeSS, which is a real point in the 2080 Ti’s favor. The B570, however, has an official frame generation path through XeSS 2 that the 2080 Ti lacks through DLSS. Which matters more depends on your game library.

Platform Compatibility: The Hidden Deciding Factor

This is where the choice often gets made, especially for older PCs:

• Resizable BAR: Arc cards need ReBAR enabled for proper performance. Platforms from roughly 2020 onward usually support it; older systems may not, and Arc performance drops sharply without it. The 2080 Ti does not depend on it.
• CPU overhead: reviewers including Hardware Unboxed found that Battlemage’s driver adds more CPU overhead than Nvidia’s, so older or slower CPUs can lose meaningful performance with the B570. Intel has reduced this with driver updates, but the 2080 Ti is the safer choice for an older processor.
• PCIe lanes: the B570 uses a PCIe 4.0 x8 link. In a PCIe 3.0 motherboard, that becomes PCIe 3.0 x8, half the bandwidth of a full x16 slot, which can hurt when VRAM overflows. The 2080 Ti uses a full PCIe 3.0 x16 link and is unaffected on older boards.

If you are upgrading a 2017-2019 era PC, these three points can easily outweigh the B570’s efficiency and newer features.

VRAM: 11 GB vs 10 GB

The memory difference is small. For current games at high settings, 1080p typically needs about 7-10 GB and 1440p about 9-12 GB. Both cards are fine at 1080p and may need lower textures in the heaviest 1440p games. Neither is designed for 4K in modern titles.

Power, PSU and Fit

Using GPU TDP + CPU + about 150 W headroom with a 105 W CPU:

• RTX 2080 Ti: 250 + 105 + 150 = 505 W, so a quality 550-650 W unit with two 8-pin cables.
• Arc B570: 150 + 105 + 150 = 405 W, so a quality 450-550 W unit with one 8-pin cable.

The 100 W gap means about 110 kWh more per year at three hours of daily gaming for the 2080 Ti, plus more heat and fan noise. Both reference designs are two slots wide, at 267 mm for the 2080 Ti and 272 mm for the B570, so case fit is similar; partner models vary.

Used 2080 Ti vs New B570: Value and Risk

Used RTX 2080 Ti cards usually sell in roughly the $200-$260 range. That puts them near the B570’s $219 launch price. With the B570 indexed at 100 and the 2080 Ti at about 110:

• Arc B570 at $219: about $2.20 per performance point.
• Used RTX 2080 Ti at about $230: about $2.10 per performance point.

On paper they are almost identical in value. The difference is risk: a 2080 Ti is now six to eight years old, often with no remaining warranty, and early 2080 Ti units had a reputation for memory-related failures. Inspect any used card carefully, ask about its history, confirm stability under a sustained load, and expect to refresh thermal paste or pads. The B570 comes new with a full warranty and many years of driver support ahead.

Pick Guide

Conclusion

The RTX 2080 Ti remains a capable 1080p and light-1440p card, and its slight average performance lead, wide DLSS support and tolerance of older platforms keep it relevant. For a modern system, though, the Arc B570 offers nearly the same gaming experience as a new, efficient, warrantied card with current display outputs and frame generation. Choose the B570 for new builds and recent PCs; choose a used 2080 Ti only when your platform or game library specifically favors it and the price is right.

Frequently Asked Questions

Is the Arc B570 as fast as the RTX 2080 Ti?

Close, but slightly slower on average. Benchmark data puts the RTX 2080 Ti roughly 5-15% ahead in typical games, with the B570 winning some titles. The gap varies a lot by game and resolution.

Does the RTX 2080 Ti support DLSS 4?

It supports DLSS 4’s transformer-based upscaling model, which Nvidia extended to RTX 20 cards. It does not support DLSS frame generation or multi frame generation, which require RTX 40 and RTX 50 cards respectively. It can use FSR frame generation in games that offer it.

Can I use the Arc B570 in an older PC?

It works, but you need Resizable BAR enabled for good performance, and older CPUs can limit it because of driver overhead. On a PCIe 3.0 board, its x8 link runs at reduced bandwidth. For pre-2020 systems, a used RTX 2080 Ti is often the safer choice.

What PSU does each card need?

A quality 450-550 W unit with one 8-pin connector is enough for the Arc B570 with a typical CPU. The RTX 2080 Ti needs about 550-650 W and two 8-pin connectors. Use separate cables rather than a single daisy-chained one where possible.

Is a used RTX 2080 Ti still a good buy?

It can be at the right price, especially for older systems. It usually sells used for roughly $200-$260. Weigh its age, lack of warranty and higher power draw against the new Arc B570 at a similar price.
