RTX 3090 vs RTX 4060: Which Graphics Card Should You Buy?

The RTX 3090 is far faster than the RTX 4060, often around 1.6x to 2x the frame rate depending on resolution. If you game at 1440p or 4K, or need lots of VRAM for AI or creative work, and your PSU and case can handle it, the 3090 is the better card. The RTX 4060 is the smarter pick only for compact, low-power 1080p builds where 115 W, a short card and DLSS frame generation matter more than raw speed. Being newer does not make the 4060 an upgrade. It is a budget card from a later generation, and the 3090 is a former flagship.

Flagship vs Entry Level: Why This Comparison Exists

These cards come up together because, on the used market, a 3090 and a new or used 4060-class card can end up closer in price than their launch tags suggest. The RTX 3090 launched in September 2020 at $1,499. The RTX 4060 arrived in May 2023 at $299. The 3090 has more than three times the CUDA cores (10,496 vs 3,072), three times the VRAM (24 GB vs 8 GB) and nearly 3.5x the memory bandwidth (936.2 GB/s vs 272.0 GB/s). The 4060 relies on Ada Lovelace’s higher clocks, 5 nm efficiency and a large 24 MB L2 cache to make the most of a narrow 128-bit bus.

Specification Table

How Far Apart Are They in Games?

Few outlets test these two head to head, but the review data lines up. Tom’s Hardware’s launch review placed the RTX 4060 around 18-22% ahead of the RTX 3060, and TechSpot / Hardware Unboxed found a smaller 9-15% lead. Both outlets placed the 4060 below the RTX 3060 Ti. The RTX 3090, meanwhile, sits near the top of the Ampere stack, just above the RTX 3080. In Tom’s Hardware’s GPU benchmarks hierarchy ray-tracing tables, the 3090 delivers roughly 2x the 4060’s frame rate at 1080p Ultra, about 2.2x at 1440p Ultra, and close to 4x at 4K Ultra, where the 4060’s 8 GB runs out.

• 1080p raster: The 3090 is typically around 60-80% faster. The gap is partly limited by CPU bottlenecks at this resolution.
• 1440p raster: Roughly 1.7x-2x in the 3090’s favor. Where a 4060 might hold 50-60 fps in a heavy AAA game at high settings, a 3090 often stays above 100 fps. These figures vary with settings, CPU and patches.
• 4K: The 4060 is simply not a 4K card. The 3090 handles 4K at high settings in most titles, especially with DLSS.
• Ray tracing: Around 2x at 1080p and widening at higher resolutions, per Tom’s Hardware’s RT results.

DLSS and Frame Generation: The 4060’s Only Trump Card

Both cards get DLSS Super Resolution, including the newer DLSS 4 transformer model, along with Ray Reconstruction and Reflex. The RTX 4060 additionally supports DLSS Frame Generation, which RTX 30 cards do not. In supported games, frame generation can roughly double the displayed frame rate on the 4060. It works best when the base frame rate is already near 60 fps, and it adds latency. Frame generation also uses extra VRAM, which the 4060 has little of to spare. Even with frame generation on, the 4060 rarely matches the 3090’s latency and responsiveness at native or DLSS-upscaled settings. Multi Frame Generation is an RTX 50 feature that neither card supports.

VRAM: 8 GB vs 24 GB

This is the biggest practical difference after raw speed. Rough budgets for modern AAA games:

• 1080p medium-high: 6-8 GB, which the 4060 can handle with occasional texture compromises
• 1440p high: 8-11 GB, beyond the 4060 in many new releases
• 4K high/ultra with RT: 10-16 GB, comfortable on a 3090

Tom’s Hardware’s later testing showed 8 GB cards suffering badly degraded 1% lows in VRAM-heavy games. The 4060’s PCIe 4.0 x8 link makes that worse on PCIe 3.0 motherboards, where overflow traffic moves even more slowly. With 24 GB, the 3090 has no such worries and can also run larger local AI models.

Power Draw, PSU and Case Clearance

A note on connectors: the RTX 4060 is sometimes listed with a 12-pin input, but most retail RTX 4060 cards use a single standard 8-pin PCIe connector. The RTX 3090 Founders Edition uses NVIDIA’s 12-pin connector with an included adapter, and most partner 3090s use two or three 8-pin connectors.

Worked PSU Sizing

• RTX 3090: 350 W + 125 W CPU + 150 W headroom = 625 W, so 750 W is the sensible minimum, matching NVIDIA’s own guidance. Use 850 W with a high-end, power-hungry CPU.
• RTX 4060: 115 W + 125 W + 150 W = 390 W, so a quality 450-550 W unit is plenty.

Physically, the 3090 is 336 mm long and three slots thick, which rules out many compact cases and some mid-towers with front radiators. The 4060 is 240 mm and two slots, and many partner models are even smaller. Heat output also differs: a 3090 can add 200 W or more of extra heat to a room compared with a 4060 under load.

Cost per Frame and the Used-Market Picture

At launch MSRP, with the 4060 as 100 and the 3090 at roughly 180 at 1440p:

• RTX 3090: $1,499 / 180 = about $8.30 per performance point
• RTX 4060: $299 / 100 = about $3.00 per performance point

Nobody pays launch price for a 3090 today. Used RTX 3090s usually trade roughly in the $650-$850 range, supported by demand from local-AI users. Used RTX 4060s usually go for around $200-$250. At those prices the 3090 costs about three times as much for roughly double the performance plus 16 GB of extra VRAM. When buying a used 3090, check memory temperatures, because GDDR6X on the back of the board ran hot on many models, and ask whether the card was used for mining.

Decision Guide by Resolution and Budget

Current-generation budget cards matter here. An RTX 5060 or RX 9060 XT lands above the 4060 for a similar price, and the 16 GB RX 9060 XT removes the VRAM ceiling that makes the 4060 a weak long-term pick.

Frequently Asked Questions

Is the RTX 4060 better than the RTX 3090?

No. The RTX 3090 is roughly 1.6x to 2x faster in most games and has three times the VRAM. The 4060 wins only on power draw, size and support for DLSS Frame Generation.

Can DLSS 3 frame generation make the RTX 4060 match the RTX 3090?

Frame generation can raise the displayed frame rate enough to look comparable on an FPS counter in some games, but input latency and image stability do not match a 3090 running at a high native or upscaled frame rate. It also needs extra VRAM that the 8 GB 4060 often lacks at higher settings. Treat it as a smoothness boost, not a substitute for raw performance.

What PSU do I need for an RTX 3090?

Plan for at least 750 W from a quality brand, based on 350 W for the GPU, a mainstream CPU and about 150 W of headroom. With a high-end CPU, 850 W gives more margin for transient spikes. Check that your PSU has the cables your specific card needs, whether that is the Founders Edition 12-pin adapter or two to three 8-pin leads.

Does the RTX 4060 need a 12-pin connector?

Most retail RTX 4060 cards use a single standard 8-pin PCIe connector, not a 12-pin or 16-pin. Its 115 W TDP is low enough that one 8-pin is more than sufficient. Always check the specific model, but most mainstream PSUs can power it without adapters.

Is a used RTX 3090 still a good buy in 2026?

It can be, especially for 1440p/4K gaming or AI work where 24 GB matters, provided the price is reasonable and the card checks out. Downsides are high power draw, size, no DLSS frame generation and no warranty on most used units. Compare it with a new RTX 5070, which offers similar or better gaming performance with modern features but only 12 GB of VRAM.
