3070 vs 3080

Since its launch late last year, Nvidia's RTX 30 series has surprised us. In fact, they are so powerful that it is difficult to know which one is right for your system and which one is completely over the top.

So to help you understand the difference between these cards, we have a head-to-head confrontation between the RTX 3070 and the 3080.

Thermal design A well-known architectural change in architecture

, marks a comprehensive transformation of the three-generation Axial

S architecture. The Turing model is a comprehensive and comprehensive Ampere microarchitecture. Some of these advancements include wider bandwidth (HBM2), smaller 8nm process nodes, 50% more CUDA cores, 3rd generation Tensor cores, and 2nd generation RT cores.

3070 is based on Ampere variant GA104300A1. Contains 5,888 shader units spread across 46 SMs, 184 texture units, 96 render units, and 184 Tensor cores for ultra-fast AI learning.

3080 is a variant of GA102200KDA1 Ampere, containing a huge 8704 shader unit, almost 3000 more than 3070. For a single GPU pass in the same series, this is a considerable leap forward. It also has a premium 88 texture units, which brings a great sense of realism to high-resolution games. However, except for the larger 5MB 1MB L2 cache and 100 extra Tensor cores, these are very similar cards.

Another big improvement we see in Ampere is how good the 30 series thermal performance is. The 3070 is capable of reaching 93 ° C before throttling and is unlikely to exceed 80 ° C under load. With a high-spec air cooler or liquid AIO (for those with the money), you can achieve a stable 5% overclocking. This is equivalent to the performance of 2080 Ti, but the cost is only a small part. The

3080 has the same heat capacity of 93 ° C that you would expect. Although it is rated at 320 watts compared to the 220 watts of the 3070, it can still reach 79 ° C under load. With a high-quality heatsink, you can achieve + 75MHz core overclocking, slightly increasing the frame rate. Both

GPUs are released with axial shields, but the Galax Classic series includes a 3080 blower version and the ASUS Turbo series provides a 3070 blower card.

We can talk about tech all day, but if these GPUs are not suitable for your situation, they are of no use to you, so let's take a quick look at the boring stuff.

For such a powerful graphics card, the size of the 3070 is very moderate, making it a suitable choice for smaller mid-tower ATX chassis. At 9.5 ”(L) x 4.4” (W) x 2 slots, it should be able to replace any mid-range to high-end graphics card without a problem.

3080 on the other hand is BIG! The dimensions are 11.2 "(L) x 4.4" (W) x 2 slots, and you need a large half tower box with sturdy brackets to accommodate this beast. It's even worth investing in support brackets to keep the GPU from sagging. The third-party iteration of the 3080 tends to be larger, so be sure to take some accurate measurements of the case before purchasing. Chapter

allows us to see the important things ... the performance of the game in the real world.

If you are a 1080p gamer, to get the performance these cards can provide, you really need a monitor with a high refresh rate. Everything else is waste. That said, we always recommend buying the latest technology and, budget permitting, buying potential displays on the track in the future.

1440p can be considered as the original resolution of 3070. You will find it difficult to find a game that does not reach the required average of 60 fps. Even in demanding games like RDRII, its average frame rate is 80fps, making it a perfect choice for 60Hz 1440p displays.

Unless you have a powerful 140Hz 1440p monitor, the 3080 is too much at this resolution. During RDRII, it pushed over 100 fps, and absolutely broke the shadow of "Tomb Raider" with an average speed of over 140 fps.

4K is where 3080 is; this is your bread and butter. Even in notorious heavyweight GPU games like "Assassin's Creed: Hall of Valor," its average frame rate has reached over 60. The 3070 provided an average of 60 fps 4K in less intense games, but we had to reduce the settings drastically to maintain the average of a wider selection of games.

As you probably know, the 30 series has the pinnacle of hardware ray tracing technology. The 20 series has moved on, but these second-gen RT cores provide twice the performance per core. My friends, this means that RT workload has little effect on 30 series cards.

3070 There are a total of 46 second-generation RT cores, a huge treasure trove of global illumination potential. In Ultra RT mode, the lights, shadows and reflections look very real, you will fully enter the world set by the game, but you can drop frames.

3080 has an impressive reserve of RT cores, 68 in total, providing exquisite lighting in games that support it, but the frames per second load can be heavy. In fact, running Ultra RT mode will downgrade the 3080 to a higher 1440p performance level.

Sometimes the difference in memory configuration in series from one GPU to the next GPU is not too great, but since Nvidia targets the original resolution of each of these cards, their VRAM specs are completely different.

3070 is equipped with 8GB GDDR6 video memory, while 3080 is equipped with 10GB enhanced GDDR6X video memory. The highest operating frequency of 6X means 760.3GBps, and the bandwidth of 3080 is almost double that of 760.3GBps.

We have good news and some ... good news! The good news is that if you choose between these cards, regardless of the outcome, you will be stuck. The other good news is that Nvidia's purpose for these two cards is very clear, you really just need to consider the current settings to decide which one is right for you.

Although the 3080 looks more like a 1440p card when ultra-ray tracing is on, it is definitely a 4K creature, well suited for 60Hz refresh rate monitors and powerful CPUs. Using it for 1440p only will only cause serious CPU and screen bottlenecks, and wasted frames is a waste of money.

On the other hand, 3070 is a 1440p daemon! If you have a 1440p 60 or even 140Hz monitor, the 3070 is the most logical choice, and it will provide you with the highest price-performance ratio of the two cards.
