[TechSpot] Navi vs. Turing: An Architecture Comparison

Source: https://www.techspot.com/article/187...-architecture/

Quote:
You've followed the rumors and ignored the hype; you waited for the reviews and looked at all the benchmarks. Finally, you slapped down your dollars and walked away with one of the latest graphics cards from AMD or Nvidia. Inside these, lies a large graphics processor, packed with billions of transistors, all running at clock speeds unthinkable a decade ago.

You're really happy with your purchase and games never looked nor played better. But you might just be wondering what exactly is powering your brand new Radeon RX 5700 and how different is it to the chip in a GeForce RTX.

Welcome to our architectural and feature comparison of the newest GPUs from AMD and Nvidia: Navi vs Turing.
Read the article for once.

I seriously cannot believe through all that, they go and do the "like for like" section and compare the 5700xt to the 2070s, do the "final word" and not once mention the price difference between the two!

Hey, here are two archs. Here they are historically. This one does this better, this one does this better, and here's why. Fantastic!

This one does multiple things better that don't necessarily affect gaming, while this one works well and is getting better. Great!

Here we compare two similar cards. They are very comparable in performance. Superb!

The end.....***.....they are not the same price, or within the same price segment. That is a MASSIVE omission!

Someone missed the title.

RX 5700 XT - 2560 Stream Processors
RTX 2070 Super - 2560 Cuda Cores

They've already covered the pricing in their review.

Availability will be key, if AMD is able to stock shelves with $400 5700 XT’s and $350 5700’s, then they will offer the best value at these price points. We're being told custom AIB models are on the way, too, and if they can boost out of the box performance a little, while bringing about the typical AIB card advantages, then Nvidia might be forced into making a few adjustments of their own and at that point we’ll have a good old fashioned GPU pricing war on our hands.

sorry then you missed the point of the article.
the prices has nothing to do with what is going on in the silicon. mentioning pricing will induce bias which any tech article should avoid. you would never read about that in any anandtech's deep dives - its research.

i guess people are so use to bias, they mistakenly believe the lack of it is bias.

Remember the golden rule of statistics: A personal sample size of one is a sufficient basis upon which to draw universal conclusions.

am i missing something or the RX 5700 XT runs at a higher clock speed and in some games gets and advantage and and in others doesnt, maybe if they made a clock per clock was more accurate?

A clock vs clock comparison isn't possible until AMD fixes their firmware or allows us to lock a boost speed.

The article was fine until they did the comparison of the 5700xt and the 2070s. Once they did that price became an omission. Both archs are parts of products which have prices and unless they are giving them away, they cannot be separated. Bias is ignoring price when it is integral.

It's worth noting that the RTX 2070 Super is not a 'full' TU104 chip (one of the GPCs is disabled), so not all of those 13.6 transistors are active, which means the chips are roughly the same in terms of transistor count.

3072 CUDA cores down to 2560 is 16.7% less cores

13.6 Billion transistors down to 10.3 is 24.3% less transistors

There is around a billion transistors missing from TechSpot's napkin math. But that is all irrelevant anyway, because Turing RTX has RT and Tensor cores, so I don't know how this comparison bears any usefulness to begin with without factoring that in, which they didn't. And by that I mean, what would the transistor count for Turing be if all the cards were, say, GTX 16 series, without the RT and Tensor cores? Would it end up having less transistors than RDNA at comparable raster core counts and perform around the same?

The non-Super RTX 2070 (10.8b) matches the transistors in the RX 5700 XT (10.3b) and it is 10% slower by their own testing. Yet, it is within the margin of error at 2% when going against the RTX 2070 Super (13.6b) and with the same amount of shaders (and same everything basically).

If anything, RT and Tensor cores are bloat at this point in time for gaming. Fun thing is that for once it wasn't AMD that jumped the gun implementing new features.

I wonder how Nvidia is facing the problem of over-provisioning die space for their next arch when it doesn't show in benchmarks. Let's not forget that the TU104 die is massive at 545 mm². That's flagship ballpark for their previous generations.
