Acer Nitro Arc B570 OC

Manufacturer: Acer

The Acer Nitro Arc B570 OC is a desktop graphics card drawing on Intel's Arc GPU architecture, manufactured at 6 nm and housing 21.7 billion transistors within a compact 268 × 113 mm frame. With a 2690 MHz boost clock and a base operating frequency of 1700 MHz, it targets users who need consistent throughput across demanding rendering and gaming workloads, all within a 150W TDP envelope.

On the memory side, the card carries 10GB of GDDR6 VRAM running across a 160-bit bus at an effective 19,000 MHz, translating to up to 380 GB/s of bandwidth. Its 2,304 shading units, 144 TMUs, and 80 ROPs contribute to a pixel rate of 215.2 GPixel/s and a texture rate of 387.4 GTexels/s, while floating-point throughput reaches 12.4 TFLOPS. Feature support includes DirectX 12 Ultimate, OpenGL 4.6, OpenCL 3, ray tracing, XeSS upscaling, and ECC memory, with display output handled through one HDMI 2.1 port and three DisplayPort connectors for a maximum of four simultaneous displays.

Pros
  • Supports up to four simultaneous displays through one HDMI 2.1 and three DisplayPort outputs
  • ECC memory support adds a layer of data integrity for workloads where memory errors are a concern
  • XeSS upscaling via XMX units provides an upscaling option without relying on DLSS
  • Ray tracing is supported, enabling hardware-accelerated lighting effects in compatible applications
  • The 160-bit memory bus delivers up to 380 GB/s of bandwidth, facilitating fast data throughput for the 10GB GDDR6 frame buffer
  • DirectX 12 Ultimate, OpenGL 4.6, and OpenCL 3 support ensures broad API compatibility across graphics and compute workloads
Cons
  • DLSS is not supported, limiting upscaling options to XeSS for users who prefer or require DLSS
  • No USB-C, DVI, or mini DisplayPort outputs, which may restrict connectivity in certain multi-monitor or legacy display setups
  • The 160-bit memory bus is narrower than wider-bus alternatives in the same card category, which can constrain bandwidth scaling
  • No RGB lighting for users who factor aesthetics into their build
  • Liquid cooling is not supported; the card relies solely on air cooling, which may affect thermal headroom under sustained loads
Who is this for?

This card suits users who need multi-display workstation setups, given its support for up to four simultaneous outputs via HDMI 2.1 and DisplayPort. The inclusion of ECC memory and broad API support — DirectX 12 Ultimate, OpenGL 4.6, and OpenCL 3 — makes it a reasonable fit for content creators and compute-oriented users who run graphics pipelines or general-purpose GPU workloads. Those who rely on XeSS-based upscaling rather than DLSS will find the XMX hardware support practical, and the 10GB GDDR6 frame buffer with 380 GB/s bandwidth accommodates texture-heavy and memory-bandwidth-sensitive tasks at moderate workload scales.

Who is this NOT for?

Users with a strong dependency on DLSS upscaling will find this card unsuitable, as that feature is not supported. The 160-bit memory bus, while functional, may prove limiting for those running extremely bandwidth-demanding workloads that benefit from wider bus configurations. Additionally, users who require USB-C or legacy DVI display connectivity will need to look elsewhere, as neither port type is available on this card. Those prioritizing sustained heavy loads in thermally constrained environments may also find the air-only cooling solution restrictive.
