| JRPGfan said: The 2700u is a 15-25w part and it can do 1.66 Tflops of compute performance with its GPU. |
Flops is irrelevant.
| JRPGfan said: If they made it run all games at half resolution when as a handheld, and when docked full res. (like a switch) where it can draw like ~25watts, |
No.
| HoloDust said: Years - I don't think many people around here quite comprehend TDP limits of handheld devices, in addition to AMD's designs being quite inferior to nVidia's in that regard. |
Indeed.
I mean... Ryzen is good. But not that Good.
And Polaris/Vega is rubbish as far as efficiency is concerned unless you start pushing lower clocks/voltages, but then you compromise performance.
nVidia has a sizable advantage.
| haxxiy said: Assuming it is made by TSMC and Nvidia, and it needs to be 6 times faster than the Switch, then: Edit - added TSMC panel from the ISS conference as evidence for any of those not used to seeing these nodes and what they really mean. Note that the increased wafer cost means every mm2 of the chip (even though transistors / mm2 still decrease in price) will be more expensive that it is nowadays, further limiting how soon the "PS4 Switch" could launch:

Fabrication process is only part of the story. Those "nodes" are more or less just advertising fluff these days and aren't an accurate depiction of the geometry sizes that chips are being fabricated at.
With that... Modern GPU's are vastly more efficient than the old, slow, archaic GPU's in the Xbox One and Playstation 4, things like Delta Colour Compression, better Culling and so on has ensured that.

think it was typical draw power. basically these small chips are limited in how much power they can draw, which limits how fast they are. |
No.
| JRPGfan said: Huh? The Switch is a hybrid device, and when docked it uses like 20-25watts too. |
TDP doesn't equal power consumption. - Anandtech pegged the Switch at less than 20w of power consumption.

A chip with less flops can beat a chip with more flops, making all of your statements and comparisons... Completely and utterly useless, nonsensical and ultimately a waste of my time to read.
| HoloDust said: I wouldn't pay much attention to what AMD is claiming - go to GFX Bench and look up 2700u vs 7850 (which is around PS4's performance) - it's more than 2x slower. AMD will get there eventually, but not just yet - and they need to have SoC that is capable of running PS4 games as they are, not with lower res/settings like with Switch where games are made from the start for both modes. |
The 2700u is bandwidth starved, The GPU is easily far more efficient... But when you hold it back with dual-channel DDR4 memory @ 2400mhz, it's not going to be setting any records on fire.
I was hoping AMD might bring back Sideport or introduce a chunky eDRAM-like cache.

Citation needed.

Thermal Design Power: https://en.wikipedia.org/wiki/Thermal_design_power Basically: how much heat can the unit produce and therefore which cooling I need. |
Something to keep in mind is that TDP is rated differently between different manufacturers too.
So a 50w AMD TDP could equate to a 25w Intel TDP and so on as one manufacturer might rate theirs for the max TDP, whilst another will use an average-TDP approach. (As chips these days have varying clocks/voltages and thus power consumption.)
| Bofferbrauer2 said: Xavier's TDP is in the 20-30W range, way too high for a hybrid console, which can stomach only up to 5W (give or take) without getting too hot or draining power too fast. |
Lower the clocks and voltages. It's not hard, Tegra X1 was pushed out as a 15w TDP part... It's definitely not that in the Switch.
Check the Anandtech link I provided earlier, you might be surprised by the power consumption numbers being thrown out.
| Mr Puggsly said: We all agree Switch is more powerful than 7th gen consoles, its still WAY BELOW the capabilities of X1. In practice I'd say its closer to 7th gen and that was his point as well. |
The Switch is also capable of far more effects than the 7th gen consoles.
It's also far more efficient.
It's a step down from the Xbox One, for sure. But it's also a step up from the Xbox 360.
The games that are available now aren't exactly shining the Switch in the best light... The console is not even a year old at this point.
I mean, Xbox One games looked and performed like shit during that consoles first year on the market. (Well. They still do.)
Give it some time before you pass judgement, you might just be surprised at what a low powered Maxwell based chip can do, it's always going to be the ugly console of this console era though... But a portable 7th gen it is not.
