If I were Nvidia I would just discontinue the GTX 1080, as it competes with the RTX 2070, and they could stop worrying about a single GDDR5X supplier for it, but keep selling the GTX 1070 and 1070 Ti, but at lower prices. The 1070 against the RX 590 wins on all fronts, it performs better and uses less power, while having the same amount of GDDR5. And then the 1070 Ti could tackle Vega 56 and also Vega 64 to some extent. The dies are small enough at 314mm2 that they can lower the prices at this point.

If TPU's latest rumoured specs for the RTX 2060 are anything to go by, it seems that it will be a harvested TU106 (RTX 2070) based card, at 445mm2, so people will be paying for the die size and Nvidia's choices, but not the performance, certainly not feasible RTX performance, and will only have 6 GB of VRAM. It will be another boring GTX 960 type of card but arguably with an even shorter shelf life.

You shouldn't expect RTX 2060 to come cheap. Nvidia is really jacking every price point up because they could now.

In reality, the lower end RTX cards will likely be sold for their non ray tracing performance.

If the RTX 2060 or whatever they call it performs as well as GTX 1070 / RX VEGA 56 under 150W while also having superior compute performance then they will have a worthwhile card. They could sell it for $350 and it would still sell.

That graph suggests that isn't the case, so I would expect it to be a $300 card or less after the initial MSRP gouging occurs. Knowing Nvidia it will launch at $400 or so since the GTX 2070 is $500.

Keep in mind the pro version of the RTX 2060 likely has to fit in a 75W TDP (P2000), if not the 105W precedent set by P4000. The RTX 4000 already sort of failed on the premise of reducing power consumption per generation, instead of 105W it has 160W TDP.
Well the leaks show that its not as fast as 1070. Probably RX 590 speeds.

How can the Vega Pro 56 be faster than the Vega Pro 64? Am I missing something here?

It's probably throttling. Anyway there's no Radeon Pro VEGA 56, it's Radeon RX Vega 56 or Radeon Pro WX8200.

It should definitely be closer to a gtx 1070 than an RX 590.

The leaks already shows this. The GTX 1070 is 7% faster in this than the RTX/GTX 2060 benchmark which is closer to the gtx 1070 than the RX 590.

If the RTX 2060 has 1536 shaders and 192 bit bus, it has the same component ratio of the GTX 1060 to GTX 1070. This being 50% more resource.

However because the performance is CPU bound and the decrease in efficiency in an architecture as it scales up, this is significantly lower in practice.



The GTX 1070 is 34.8% faster than the GTX 1060.

So if the differential in performance is the same, to get the performance of the 2060, we simply have to divide the 2070's by the 1.348 which translates into 160/1.348 = 118.69 which is very similar to the GTX 1070s score of 120.

Another calculation to determine the 2060's performance is to determine the IPC gain of RTX in terms of performance per tflop.

To ensure we are not CPU bound to make this calculation, we have to look at the 4k Results. This is fair for the RTX 2060 because it is unlikely to be CPU bound like the RTX 2070/280 at 1080p meaning it will be able to achieve it's optimum performance per flop unlike the GTX 2070/2080 at CPU bound(which is illustrated by the 1.35 performance advantage of the GTX 1070 over the 1060).

So if we consider the GTX 1080 at 9.01 tflop card considering the GTX 1080 1760mhz running clock and the RTX 2080 as a 11.18(the actual clocks on the cards at 1900mhz) and look at the difference in performance in the same chart below(notes most of these clocks are coming from Ananddtech),



We see there is a 44.1% gain in performance. From the above, you can determine the gtx 2080 has a 1.242 tflop advantage

1.44.1= tflop advantage* performance per tflop 144.1/ normalized tflop advantage = perfomance per tflop.

1.441 /1.242 = 1.160

Similarly for the RTX 2070 vs gtx 1070, 1.4333 difference in performance.

The 1070 has clocks about 1779mhz(6.83tflops) and the rtx 2070 has clocks of 1803mhz(8.31tflops) = 1.217

1.43/1.217 = 1.178 advantage in t flops. This being higher should be no surprise as an architecture scales worse per tflop. So lets take this performance per tflop and times it by the tflop ration difference between the gtx 1060 and 2060.

Lets make this last calculation simpler and assume the clocks will be the same and the difference will be entirely related by the number of cores. Since he RTX 2060 has 1536 cores and the gtx 1060 has 1280 cores, the RTX 2060 has 1.2times the number of cores and lets assume for now tflops.

Take an aggregate average from the above and say the 1.17 advantage for performance per tflop.

To get the actual performance, you take 1.17 *1.2 = 1.404.

This means that a RTX 2060 should be 40.4% faster than a GTX 1060 atleast in less CPU bound situations. This puts it around GTX 1070 level in performance which I suspect it will be at. Definitely not RX 590 levels of performance because for that to happen, the RTX 2060 would have to a regression in performance per tflop because the 20% increase in cores should put it slightly above an RX 590 alone, add in the increase performance/tflop and you got something that should be substantially faster. What I suspect will happen is the 2060 will be about 35% faster than a gtx 1060 at 1080p but end up being 40% faster at 1440P.

While I don't think it will outperform the GTX 1070 which has 1920 shaders, it's quite possible it is close if there's an IPC gain to make up the 25% difference in CUDA cores. The graph in the first post suggests it is within a few percent of GTX 1070 and 30% ahead of GTX 1060 6GB.



There's literally no way it's slower than GTX 1060 or RX 590. The clocks would need to be outright terrible.

maybe for a 75W version, though i doubt they'd use something like the RTX 2060 for that.

trolling an adult is very dangerous, don't try it at home nor at work. you don't want to play tag with a rabid man.

AdoredTV said a while back in the Turing speculation video that the GTX/RTX 2060 would be around 27% faster than the GTX 1060, and thus still slower than the GTX 1070, so it adds up to this leak.

Remember when the GTX 1060 was as fast as a GTX 980 and not behind a 970.

Not even as fast as a 2.5 year old GTX 1070, why would anyone get this? This card is an absolute waste of money and time.

I can't wait to see the price... Anything over $250 is a complete and utter failure. *Even if it's a true RTX card.* My 2 cents.

I own a GTX 1060 and was looking forward to this card but now I know for sure I'm skipping this generation of Nvidia's cards. Hopefully AMD has something worth wild up their sleeve.

I'm not expecting anything lower than $300 unfortunately; it will be a GTX 960 type of card, but without the lower price part, which was that card's saving grace back then. If they are really confident in their mindshare, they'll go all the way up to $350, but in my opinion they'd have to be insane to think that is anywhere near reasonable.

Then again, at $300 there is a $200 gap to the absolutely cheapest RTX 2070, so who knows. Maybe we'll get a 2060 Ti too this time around, although I don't see the timeframe for it honestly, even the 2060 at this point makes less and less sense with 7nm next year, and I bet that the 1060 overstock is messing up with Nvidia's plans, as they have stated that they only expect the midrange card overstock problem to clear in one or two quarters.

And unfortunately AMD doesn't have anything any time soon. They just released the RX 590 and while the 7nm Vega (aka Radeon Instinct MI60) is now starting to sample to professionals, at the end of the day, at its core, it's still the same unbalanced, power hog Vega 64 design with higher clocks and a 300w TDP, it's not Navi.

Don't expect any actually new GPU from AMD until at least six months from now.
