How well do the GTX 1660 Super and Ryzen 5 2600 match?
Pairing at a glance
- Assessment
- CPU limits
- Primary limitation
- The CPU is holding the graphics card back
- Best Use Cases
- 1080p High: CPU-limited – uneven frame pacing · 1080p esports: Clearly CPU-limited · 1440p Medium: GPU-limited

Editorial assessment; not a measured pairing benchmark. Methodology
A widespread 2019 build that is clearly CPU-limited today. The GTX 1660 Super is still usable for 1080p, but the Zen+ based Ryzen 5 2600 delivers weak minimum frame rates. The good news: the fix is cheap, because AM4 allows an upgrade without changing the board.
Expected frame rates
| Resolution | Frame rate | Assessment |
|---|---|---|
| 1080p High | 60–90 FPS | CPU-limited – uneven frame pacing |
| 1080p esports | 140–200 FPS | Clearly CPU-limited |
| 1440p Medium | 45–60 FPS | GPU-limited |
Reference values for current AAA titles without upscaling unless stated otherwise. Real values depend on the game, settings and cooling.
Basis for the assessment: published manufacturer specifications and public benchmark hierarchies, applied to this pairing – TechPowerUp GPU Database, Tom's Hardware GPU Hierarchy, ComputerBase GPU Benchmarks.
Strengths
- Very low power draw, runs on 450 W power supplies
- AM4 allows a major CPU upgrade without a rebuild
- Still entirely sufficient for older titles and esports
Weaknesses
- Zen+ has weak latencies and low minimum frame rates
- No DLSS and no usable ray tracing on the GTX generation
Optimal memory speed for this CPU
Ryzen 5 2600 · AM4 (DDR4, Zen 2 / Zen+)
2× 16 GB DDR4-3200 CL16, XMP/DOCP enabled
Zen 2 holds 1:1 sync reliably up to DDR4-3600, but DDR4-3200 CL16 is the practical, cheap choice – the gap to 3600 is only 1–3 %. What really matters here is dual channel: Zen chips lose 15–25 % in games on a single module because the chiplet design depends on memory bandwidth. Zen+ (Ryzen 2000) gains almost nothing beyond DDR4-3200.
VRM note (power delivery)
These CPUs stay under 105 W and run on virtually any B450 board. The only caveat is very cheap A320 boards, where the power stages have no heatsink – that costs clock speed with 8-core parts under sustained load.
Sensible upgrades
The biggest AM4 upgrade – removes the stutter on the same board.
The cheap option with most of the effect.
Zen benefits above average from fast dual-channel memory.

Frequently asked questions
Why does it stutter despite decent average FPS?
That's the classic CPU-limit pattern: averages look fine while minimum frame rates collapse. Moving to a Zen 3 processor resolves it on the same board.
CPU or graphics card first?
Clearly the CPU. A new graphics card would immediately be held back by the Ryzen 5 2600.
