RTX vs GTX
Both are NVIDIA GPU product lines. GTX is the older generation (up to 16-series). RTX (20-series onwards) adds ray tracing and DLSS — AI-based upscaling that boosts frame rates significantly. For gaming in 2025, RTX 30-series refurbished is the practical sweet spot.
What It Is
NVIDIA has used several naming prefixes over the years. The shift from GTX to RTX marked the introduction of dedicated ray tracing cores and Tensor cores for AI-based upscaling (DLSS).
| Prefix | Generation | Key Feature |
|---|---|---|
| GTX | Up to 16xx series | Traditional rasterisation, no ray tracing |
| RTX 20-series | 2018–2019 | First-gen ray tracing + DLSS 1.0 |
| RTX 30-series | 2020–2021 | Mature ray tracing + DLSS 2/3, best refurbished value |
| RTX 40-series | 2022–present | DLSS 3 Frame Generation, high new-retail price |
Why RTX 30-Series Is the Sweet Spot
The RTX 30-series hit the market in 2020–2021 and remains highly capable for gaming today. It’s old enough that refurbished prices are excellent — but new enough that drivers, game support, and DLSS performance are all fully current.
RTX 40-series new cards are significantly more expensive for incremental gains in most gaming scenarios. For most Singapore gamers, a refurbished RTX 3070 or 3080 delivers better value than a new 40-series mid-range card.
What DLSS Actually Does
DLSS (Deep Learning Super Sampling) uses AI to render frames at a lower resolution and upscale them to your target resolution. In practice, this means a game rendering at 1080p internally can display at 1440p quality — with significantly higher frame rates. RTX 30-series supports DLSS 2, which is mature and widely supported across hundreds of games.

People Also Ask
Is GTX still worth buying in 2025?
For light gaming or older titles, yes. For modern AAA games at 1440p or 4K, RTX 30-series refurbished is better value — DLSS support alone makes a significant difference in frame rates.
What does the Ti mean in RTX 3070 Ti?
Ti (Titanium) is NVIDIA’s designation for a faster variant within the same generation — more shader cores, higher clock speeds. The RTX 3070 Ti sits between the 3070 and 3080 in performance and is an excellent 1440p–4K card.
Is RTX 30-series still supported?
Yes — NVIDIA continues to release driver updates for the 30-series and it will remain supported for years. DLSS 2 is supported in hundreds of games and continues to receive new game support.
