If you have been sitting on an nvidia rtx 4070 and wondering whether the shiny new nvidia geforce rtx 5070 is actually worth the extra spend, you are not alone. It is one of the most talked-about GPU debates of 2026, and honestly, it is a fair question. Both cards sit in that sweet mid-to-high range that most UK gamers actually buy into, not too cheap, not stratospherically expensive.

In this guide, we break everything down clearly. No jargon overload, no padding. Just the real differences, the real numbers, and a clear answer to whether you should upgrade right now.

What Is the Nvidia GeForce RTX 5070?

The nvidia geforce rtx 5070 is part of Nvidia's brand-new Blackwell generation of graphics cards, launched in early 2025. It replaces the RTX 4070 in the mid-high tier and brings a number of meaningful architectural improvements under the hood.

Here is what sets it apart from its predecessor:

• New Blackwell GPU architecture - a significant generational leap over the Ada Lovelace chips in the 40 series

• 12GB GDDR7 VRAM - faster memory with higher bandwidth compared to the GDDR6X in the RTX 4070

• Fifth-generation Tensor Cores - enabling improved DLSS 4 with Multi Frame Generation

• Fourth-generation Ray Tracing Cores -— built for what Nvidia calls "Mega Geometry," meaning more complex lighting in games

• DLSS 4 with AI Frame Generation - can generate up to three additional frames for every real frame, pushing frame rates to new levels

• PCIe Gen 5 support - future-proofed for the next generation of motherboards

In short, it is not just a minor refresh. The jump from Ada to Blackwell is a proper architectural shift.

RTX 4070 vs RTX 5070: Key Specs Side by Side

Specification	RTX 4070	RTX 5070
Architecture	Ada Lovelace	Blackwell
CUDA Cores	5,888	6,144
VRAM	12GB GDDR6X	12GB GDDR7
Memory Bandwidth	~504 GB/s	~672 GB/s
TDP (Power Draw)	200W	250W
DLSS Version	DLSS 3	DLSS 4
Ray Tracing Cores	3rd Gen	4th Gen
PCIe	Gen 4	Gen 5

Looking at raw specs, the gains are real. More CUDA cores, faster GDDR7 memory, and a new generation of AI and ray tracing hardware all add up.

How Much Faster Is the RTX 5070 Than the RTX 4070?

This is the question most people actually want answered, so let us be direct.

In standard rasterisation gaming (which is what most people actually play):

• 1080p gaming: The RTX 5070 is approximately 25 to 35% faster than the RTX 4070 in rasterisation alone

• 1440p gaming: Expect gains of around 30 to 40% at this resolution, where the RTX 5070 really starts to shine

• 4K gaming: Here the RTX 5070 handles 4K much more comfortably, where the RTX 4070 could struggle to maintain smooth frame rates in demanding titles

With DLSS 4 Multi Frame Generation enabled, the performance gains become even more dramatic. In supported titles, the RTX 5070 can deliver frame rates that are effectively double or more what the RTX 4070 produces. This is a game-changer for high refresh rate monitors.

For ray tracing specifically, the 4th generation RT cores in the 5070 handle complex lighting scenarios noticeably better, particularly in titles like Cyberpunk 2077 with full path tracing enabled.

RTX 5070 vs 4070 Super: What About the Super Variant?

The RTX 4070 Super was Nvidia's mid-generation refresh, sitting between the vanilla 4070 and the 4070 Ti. So how does the rtx 5070 vs 4070 super comparison shake out?

The rtx 4070 super vs 5070 situation looks roughly like this:

• The RTX 4070 Super is a solid card with 12GB GDDR6X, 7,168 CUDA cores, and a 220W TDP

• In rasterisation at 1440p, the RTX 5070 is still around 20 to 28% faster

• In ray tracing and DLSS 4-enabled titles, the gap widens considerably in favour of the 5070

• The 4070 Super remains a great card for 1440p gaming but lacks the AI-accelerated frame generation of DLSS 4

If you currently own an RTX 4070 Super, the upgrade to the 5070 is less urgent than coming from a vanilla 4070, but it is still a meaningful step up, especially if you game at 1440p on a 144Hz+ monitor or want to push into 4K.

What About the MSI Nvidia GeForce RTX 5070 Ti?

If you want to take things further, the msi nvidia geforce rtx 5070 ti represents the step above the standard 5070. With 8,960 CUDA cores and 16GB of GDDR7 memory, it is built for those who want the best performance below the top-tier RTX 5080 and 5090.

You can find the PNY NVIDIA GeForce RTX 5070 Ti 16GB GDDR7 available at PC Gaming Cases. This particular card features:

• 8,960 CUDA Cores for serious gaming and rendering workloads

• 16GB GDDR7 VRAM with 896 GB/s memory bandwidth

• 2295 MHz core clock speed

• Triple fan cooling with a metal backplate for extra stability

• Support for 4K at 480Hz or 8K at 165Hz with DSC

It is the choice for gamers who want a top gaming PC setup that will stay relevant for the next three to four years without compromise.

Top Reasons to Upgrade from RTX 4070 to RTX 5070

Here is a quick summary of who should seriously consider making the move:

• You game at 1440p on a 144Hz or 165Hz monitor and want consistently high frame rates in all modern titles

• You are planning to move to 4K gaming in the near future and want a card that can handle it properly

• You use ray tracing regularly and want smoother performance in titles with demanding lighting effects

• You want DLSS 4 and Multi Frame Generation for significantly boosted frame rates in supported games

• You are building a new top gaming PC from scratch and want to start with a card that is properly future-proofed

• You edit video or do creative work alongside gaming, where GDDR7 and 5th gen Tensor Cores provide real benefits

When Sticking with the RTX 4070 Still Makes Sense

Not every upgrade makes financial sense for every person. Here are cases where staying on the RTX 4070 is the smarter call right now:

• You game primarily at 1080p and are happy with your current frame rates, the RTX 4070 is still very capable here

• Budget is the priority and the RTX 5070's current pricing feels steep for your setup

• You just bought your RTX 4070 recently and it is still delivering smooth gameplay in your current games

• Your monitor is a 60Hz or 75Hz display where the extra performance is not going to be visible anyway

How to Choose the Right GPU for Your Build

Not sure which card is right for you? Here are some quick questions to ask yourself:

What resolution do you game at?

• 1080p: RTX 4070 is still capable; 5070 is overkill unless you want headroom

• 1440p: RTX 5070 is the better long-term choice

• 4K: RTX 5070 or 5070 Ti is the right pick

What is your monitor's refresh rate?

• 60Hz: Either card is fine; you will not see the difference

• 144Hz+: The RTX 5070 will better utilise your display's potential

How long are you planning to keep this GPU?

• 2 to 3 years: RTX 4070 may still serve you well, especially if prices drop

• 4 to 5+ years: RTX 5070 is the better investment for longevity
