Nvidia RTX 4070 vs 3070 improved entry level

For yet another comparison, we see what to expect for the RTX 4070 vs 3070. The lower-end choices for the initial release of the graphics card series.

The series has become more popular with a slightly cheaper price tag on it. While also still providing good performance on top of it. For release dates, the RTX 3070 has been around for a couple of years now. It launched in October 2020 a bit further down the line from the 20 series launch.

Although plagued with the GPU shortage there wasn’t much stock of the card. Many were not able to buy the card but now there has been some improvement.

Whilst the RTX 4070 is rumored to launch in April 2023. That’s only rumored so it still may change. Even with that, we can compare what we know so far to know what to expect from your next best graphics card.

Architecture

Being in two different generations there is a change in how they are built. Nvidia has moved from the Ampere architecture in the 30 series to the Ada build in the RTX 4000 series.

Specifically, the 3070 is using the GA104-300 GPU variant. Built with Samsungs 8nm process, it has a die of 392mm² featuring 17.4 billion transistors.

Whilst the 4070 is likely an AD104-250 GPU variant. Based on TSMC’s 5nm process it has a die size of 295mm² with yet an unknown transistor count. Although it is likely the newer chip will contain more. With a more compact build possible it could fit more in.

These specifications are based on leaks and rumors for the 4070. So they may not be final and can change up until the launch.

But we can get a basic understanding of what to expect between the RTX 4070 vs 3070. While also updating with the latest when it comes, we take a deep dive into what the specs mean.

CUDA cores

Compute Unified Device Architecture is Nvidia’s parallel processing system. It is an ecosystem to improve the processing of graphics on the card.

It allows for the GPU cores to work together splitting the workload and improving the speed of processing with what it can achieve. Although we can compare the numbers available, the efficiency and how it works change between the generations.

The 3070 itself contains 5,888 CUDA cores inside of its core. While the 4070 is rumored to contain 5,888. So it is possibly the same count. But the Ada ones improve in their performance. As such it will still likely offer a better performance per core.

Frequency

The frequency or clock rate is the oscillation of silicon crystals inside the wafer. It determines how fast the GPU can process instructions. With faster rates able to get through the data and create the graphics to see your final image.

As there is some control over the spec it is a target for overclocking. This allows you to push the rates above but at the cost of power and heat.

If the new specs are correct, the new generation will see an increase in the overall clock rate. The 4070 has a supposed 1,920 MHz base clock and a boost of up to 2,475 MHz.

A big improvement over the previous gen and closer to what AMD had to offer on its Radeon cards. As we see the 3070 with a base clock of 1,500 MHz. Whilst reaching a boost clock of 1,750 MHz and a max boost clock of 1,890 MHz.

Which pushes the clock rate over 2 GHz to push the performance of the card over that line. And so further improving what they can achieve.

VRAM

In terms of video memory, there are also some improvements. But first, we see what it actually does. Its purpose of it is as a frame buffer and pixel store. So that you can experience smooth framerates and lower latency. Especially useful for higher resolutions like 4k. As they have much larger pixel requirements.

Between the RTX 4070 vs 3070, there is a change in capacity and speed. The 40 card bearing 12GB of GDDR6X memory, clocked at 21 Gbps across a 192-bit bus gives a 504 GB/s bandwidth.

Whereas the 3070 is fitted with 8GB of GDDR6 memory. Clocked at 14 Gbps across a 256-bit bus it has a bandwidth of 448 GB/s. Another area in which the new card has an advantage.

TBP

TBP is the total board power of the card. It is an indicator of much energy the GPU will consume at max utilization. As well as giving you an estimate of how much heat it will give off. Since the work put into running that chip is converted to waste. So it gives an idea of your power bill as well as how much of a radiator it will be.

With the increased power of the new card, we also see an increase in power consumption. As the 4070 is said to have a total card power of 250W.

Whereas, the 3070 sits with a 240W TDP. So although the newer card does require more power it should bring more performance. Therefore we will have to rely on performance per Watt and price comparison.

Price comparison

Comparing the RTX 4070 vs 3070 on the price we have to do some speculation on it. As it is one of the last things to be confirmed on the card.

So we look back at what previous offerings have to offer and likely increase above that. But the RTX 3070 initially came out with an MSRP of $499 USD/£469.

This would likely be the base price of the 4070 but we could expect a price increase. So we speculate it will cost in the range of $499-$649USD/£469-599.

Especially as the Ada releases to date have been a lot more expensive we would expect the 4070 to be increased as well.

Is the 4070 worth it over 3070?

It will be best to wait for reviews to come out before deciding on the RTX 4070 vs 3070. This will give us a better understanding of what to expect between the two.

But from the current specifications and performance, it is easy to say the 4070 is the better option. With the likely higher performance but coming at the cost of price and power.

RTX 4070 vs 3070 FAQs

How much faster is 4070 than 3070?

From the rumored specs the 4070 is over 500 MHz faster than the 3070. That is across the base, and boost clocks. Specifically, it is rumored to have a 1,920 MHz base clock and a 2,475 MHz boost clock. Whereas the 3070 has a base clock of 1,500 MHz and a 1,725 MHz boost clock.
