Quick Answer
For SA gamers, the RTX 5070 is the smarter buy over the RTX 4070: it delivers around 20-30% more frames at 1440p plus multi-frame DLSS generation, while costing similarly when bought new. Only choose the RTX 4070 if you find one at a clear discount around R10,000 and don't need the newer DLSS features.
How they stack up at 1440p
The RTX 5070 builds on the 4070 with a newer architecture, pushing roughly 110-130fps in titles like Cyberpunk 2077 and Alan Wake 2 at high settings with DLSS. The RTX 4070 remains a strong 1440p card, holding around 90-110fps in the same games, but it lacks the latest multi-frame generation that smooths demanding scenes. Both carry 12GB VRAM, enough for 1440p but worth watching at 4K. For esports, both clear 200fps easily.
Plan for case airflow too, since the newer card runs warm under sustained loads, and steady cooling keeps frame rates consistent across long sessions. Confirm your power supply has the right PCIe connectors before ordering to avoid a frustrating delay.
Value and power for SA builds
At Evetech, the RTX 5070 typically sits a little above the discontinued 4070's pricing, so a new 4070 is only worth it at a genuine markdown near R10,000. The RTX 5070 draws roughly 250W and pairs with a 650W power supply, similar to the 4070. Check case length, since some models exceed 300mm. A 1440p 144Hz monitor is the natural partner for either card, giving smooth play without overloading the GPU.
FAQ
Is the RTX 5070 worth it over the 4070?
Yes when bought new, since it adds 20-30% more frames and newer DLSS generation for a similar price. The 4070 only wins at a clear discount.
How much VRAM do these cards have?
Both carry 12GB, which is comfortable for 1440p gaming. Keep an eye on it at 4K in the most texture-heavy modern titles.
What power supply do I need?
Plan for a 650W unit for either card, as both draw around 250W. Confirm your PCIe cabling matches the model you choose.
Confirm a 650W power supply and check case length up to 300mm, then contact Evetech to verify current stock and pricing.
