Why a single percentage is usually misleading
"Card A is 15% faster than card B" is only true at one resolution, in one workload. Two cards with similar shader throughput but different memory bandwidth can be level at 1080p and separated by a wide margin at 4K, because bandwidth pressure grows with pixel count. That is why the table above breaks the comparison out by resolution rather than reducing it to one number.
Processor comparisons have the same problem in reverse. Two chips can be indentical in a graphics-limited game and far apart in a simulation title that hammers a single thread. Comparing across several games is the only honest way to do it.
When performance is not the deciding factor
If two parts land within a couple of percent, performance is not what should decide it. At that margin the differences that matter are the ones a benchmark chart does not show.
- Memory capacity ages far less gracefully than raw speed. Between two cards of similar performance, the one with more video memory will still be usable after the other starts compromising on textures.
- Power draw against the supply you already own. A card that needs a new power supply is not the price on the label — our PSU calculator will tell you whether that applies.
- Physical size against your case, and the number of slots the cooler occupies. Modern high-end cards are large enough that this is a genuine constraint.
- Price today, not at launch. Recommendations written a year ago are often obsolete purely because the market moved.
- Platform cost, for processors. A chip on a different socket brings a motherboard and often memory with it.
Newer does not mean faster
A previous-generation flagship frequently beats a current-generation mid-range card, and often costs less on the second-hand market. Generation number tells you about feature support and efficiency, not about where a part sits in the performance range.
What the newer part usually does bring is access to features the older one lacks — newer upscaling implementations, hardware encoders, and better ray tracing throughput. Whether that matters depends entirely on whether you use them. If you play rasterised titles at 1440p, an older, faster card is often the better buy.
Reading a processor comparison
Processor comparisons have the opposite problem to graphics cards. Two chips can be identical in a graphics-limited game and far apart in a simulation title that hammers a single thread, which is why the table above compares across several games rather than reducing everything to one figure.
Two things drive most of the difference. Single-thread speed decides the ceiling in almost every game, because the render thread is the critical path. Cache size matters more than the specification suggests, which is why large-cache parts beat higher-clocked siblings in games while looking unremarkable in productivity work. Our processor pages break both down per chip.
Common questions
Why does the difference change with resolution?
Because the bottleneck moves. Two cards with similar shader counts but different memory bandwidth can be level at 1080p and far apart at 4K, since bandwidth pressure grows with pixel count. A single percentage that ignores resolution is hiding the part you needed to know.
Why compare both parts against the same partner component?
Otherwise you are comparing two whole systems rather than two parts. If one card is tested with a fast processor and the other with a slow one, the gap you see is partly the processors. Holding the partner constant isolates the difference to the parts themselves.
Two parts are within a few percent. Which should I buy?
Not the faster one, necessarily. At that margin the deciding factors are memory capacity, which ages far less gracefully than raw speed, power draw against the supply you already own, physical size against your case, and price today rather than at launch.
Is a newer part always faster than an older one?
No. A previous-generation flagship frequently beats a current-generation mid-range card, often at a lower price second-hand. Generation number tells you about features and efficiency, not about position in the performance range.
