Overclocking can make an 8 GB graphics card look a lot better on paper, but it doesn’t erase the gap to 16 GB models when games start leaning hard on VRAM. That’s the blunt takeaway from this PC test of the RTX 5060 Ti 8 GB, RX 9060 XT 8 GB, RTX 5060 Ti 16 GB, and RX 9060 XT 16 GB on PC. If you’ve been wondering whether a few extra MHz can save you money without costing performance, the answer is: sometimes, but not always where it matters.

That distinction matters for real players because benchmark charts can flatter a cheap card while actual game worlds expose the limits. In lighter tests, the overclocked 8 GB cards can keep up or even jump ahead, but in VRAM-heavy games like Cyberpunk 2077 and The Last of Us Part 1, the 16 GB cards still hold the smoother line. If you’re shopping the budget end of the market, this is exactly the kind of result that can stop you from buying the wrong card for the games you actually play.

What Is This 8 GB vs 16 GB Overclocking Test?

This PC test compares stock and overclocked performance across the RTX 5060 Ti 8 GB, RX 9060 XT 8 GB, RTX 5060 Ti 16 GB, and RX 9060 XT 16 GB. The setup also includes the Palit Infinity 3 RTX 5060 Ti 16 GB, an Asus sample, and an XFX sample, with the overclocking work focused on core clock and memory speeds. The point is simple: see how far the smaller VRAM cards can be pushed before the 16 GB versions pull away again.

That makes this less about synthetic bragging rights and more about buying advice. The article’s conclusion is clear that overclocking can improve benchmark results, but real-world VRAM limits still block parity in some games. For anyone deciding between 8 GB and 16 GB, that’s the part that should stick in your head, not the occasional chart win.

ℹ️ Note: The tests compare stock and overclocked results on PC, including 1080p gaming benchmarks, 1440p gaming benchmarks, and in-game VRAM testing.

Overclocking Methodology and What Changed

The overclocking method stayed deliberately straightforward. The cards were pushed with higher core clocks and memory speeds, then run through demanding benchmarks until they crashed, before the settings were backed off to stable levels. That approach matters because it reflects what most players can realistically do without chasing tiny gains and running into stability problems.

Those figures tell you something important about the test conditions. The RTX 5060 Ti 8 GB couldn’t go beyond +350 MHz core and +500 MHz memory without a power boost, while the RX 9060 XT 8 GB and the Asus sample each needed different tuning to stay stable. In plain English, overclocking isn’t one-size-fits-all, and the best result depends on the exact card in your hand.

Overclocked 8 GB Graphics Cards at 1080p and 1440p

At 1080p, all of the 8 GB cards showed average frame rate gains over stock. That’s the easy part, and it’s the part that can make overclocking look like free money. The RX 9060 XT 8 GB stood out in The Talos Principle 2, where it gained 10 frames over stock and shot from the bottom of the results to the top.

F1 24 produced another sharp jump, with the same 8 GB card gaining 12 frames on average. Even so, the RTX 5060 Ti 8 GB still came out ahead of the RX 9060 XT 8 GB in stock-to-stock and overclocked-to-overclocked comparisons. Once the AMD card got its speed bump, though, it could jump ahead of the stock Nvidia card, which makes a decent case for squeezing extra performance out of the cheaper option.

At 1440p, the gains got smaller, which is exactly what you’d expect when the resolution climbs. The RX 9060 XT 8 GB still benefited, but Cyberpunk 2077 exposed its weakness: the average frame rate stayed exactly the same whether the card was stock or overclocked, while 1% lows improved by two frames. That’s the sort of result that looks fine in a chart and still feels rough in play.

The RTX 5060 Ti 8 GB did better at 1440p, with solid gains once overclocked, though nothing dramatic. It remained the top performer on average at that resolution, even as the RX 9060 XT’s overclock narrowed the gap. For players, that means the Nvidia card still has the cleaner headroom story, while the AMD card remains more sensitive to the game you throw at it.

Overclocked 16 GB Graphics Cards and Their Limits

The 16 GB cards started from a stronger place, with higher frame rates overall. Their overclocking gains, however, were usually modest. The RTX 5060 Ti 16 GB did post an eight-frame jump in Cyberpunk 2077 at 1080p from a core overclock alone, which is a meaningful gain in a demanding game that can punish weaker hardware hard.

The RX 9060 XT 16 GB was less cooperative. The XFX sample didn’t respond as well to power fiddling, and the gains stayed smaller than the rest of the group, though Metro Exodus Enhanced edition still delivered an extra 4 fps and a 27 fps improvement in 1% lows. That matters because low-frame-time stability often feels better than a bigger average number, especially in busy scenes where stutter stands out.

At 1440p, the story stayed familiar for both 16 GB cards. The gains were there, but they were usually only three or four fps, with the RX 9060 XT 16 GB again standing out in Metro Exodus by gaining nine frames. That’s useful, but it also underlines the bigger point: overclocking helps, yet it doesn’t transform these cards into something else.

What the 8 GB vs 16 GB Results Actually Mean

When the 8 GB and 16 GB results get compared directly, the benchmark wins for the smaller cards are real. The overclocked RX 9060 XT 8 GB can beat the stock 16 GB version in Black Myth Wukong at 1080p High, and it can even match the averages exactly in some cases. Homeworld 3 also produced a nine-frame win for the overclocked 8 GB AMD card, though the article notes that the benchmark can be twitchy.

Still, Cyberpunk 2077 keeps dragging the conversation back to VRAM. The overclocked RX 9060 XT 8 GB gets within 2 frames of the stock 16 GB GPU on average, but its 1% lows tell a harsher story, and the card drops frames fairly often when it only has 8 GB of VRAM to work with. That’s the real-world problem here: the benchmark may say “close enough,” while the game itself says “not quite.”

The Nvidia side tells a slightly different story. The overclocked RTX 5060 Ti 8 GB beats the stock RTX 5060 Ti 16 GB in all but one 1080p test, and it continues to do well at 1440p. Even there, though, the mildly overclocked RTX 5060 Ti 16 GB remains the clear winner in most tests, which is exactly why the extra VRAM still matters when the game starts asking for more than the smaller card can comfortably give.

Where the Benchmarks Stop Telling the Full Story

This is where the article lands its strongest point. In-game VRAM testing of The Last of Us Part 1 on Ultra settings shows a much uglier gap than the benchmark charts suggest, and Resident Evil Requiem shows a similar performance delta at certain settings. The tests used actual game-world play rather than a lighter benchmark tool, and that difference matters because benchmark tools are simply lighter on VRAM than actual game worlds.

That’s why the article says overclocking may narrow the gap, but it probably won’t create parity when VRAM limits bite. The author is blunt about it: in actual gameplay, the 8 GB cards can’t be trusted to match their 16 GB equivalents in some games, even if the benchmark numbers look encouraging. For players, that means an 8 GB overclock can be a useful fix, but not a magic trick.

⚠️ Heads Up: Cyberpunk 2077 can expose the flaws of a tight VRAM limit, and the 8 GB card has a tendency to drop frames fairly often when faced with only 8 GB of VRAM.

The verdict here is straightforward. Overclocking can absolutely help an 8 GB card, and in some benchmark runs it can even make the smaller model look like the smarter buy. But if your games lean hard on VRAM, the 16 GB version still has the safer, smoother ceiling, and that’s the card I’d trust for long-term use. If you’re on a budget, the 8 GB model can still make sense, but only if you know exactly what you’re giving up.
