Trying to find the fatest reaction, responsiveness, keyboard out on market!

[adsfpoi]

hello geekhacks

Like in the subject I'm trying to find out which techincally and THE FASTEST keyboard

I picked some out so you guys can tell what is better in only on fast reaction, responsiveness, debounce time,input lag etc.  (don't care how it looks, keycaps, build quality waht so ever only fastness!)

Cherry mx board 6.0, corsair rapid fire k65 k70, realforce topre keyboards, cooler master novatouch, logitech romer-g keyboards, steelserires apex I think thats about it?

thank you so much for reading my pointless fatstness!!!!!! I'm just Fast junky...

I hope i get distinct answer! so i can buy the fastest one!

I don't think any digital keyboard can beat the Wooting One. The sub-ms input lag is below what USB is capable of.

what if you choose from above? and when is wooting one released?

Of the ones on your list, the Romer-G cones out the fastest in all the tests I have seen, probably because of the same Logitech debouncing magic in some of their gaming mice. MX6.0 is a fraction of a ms slower, the topre boards both 1-2ms behind that (slower than you'd expect, really), and then the Corsair stuff and other regular mechs are way behind, another 15ms or more. Can't recall any numbers for M800, but in the absence of any reason to think otherwise I'd assume it's in the slow category with the Corsairs.

Optical and Hall effect keyboards can be a fraction of a ms faster even than Logitech. If you don't want to wait for Wooting, there are optical keyboards from Bloody that you can get now.

In all switches where electrodes meet to create a circuit there is "bounce", which must be taken into account. This goes for all membrane switches and all mechanical switches with metal-to-metal contact. The signal has to be "debounced" by waiting a few milliseconds for bouncing to stop. This delay is usually incurred both at press and release.
Cherry MX-board 6.0 uses regular Cherry MX switches - it just does debouncing in a analogue way where as most other keyboards do it digitally.

The only way to avoid a debouncing delay is to use another type of sensing that does not require debouncing:
Those include switches with optical or capacitative sensing.
Wooting One (Adomax Flaretech switches) and some Bloody keyboards (Lightstrike switches) have optical sensing.
Realforce, HHKB, Novatouch and TypeHeaven (Topre switches) and Royal Kludge (Topre clone) have capacitative sensing.
All those should be faster than a mechanical keyboard.

That PS/2 should be faster than USB is a myth. Or actually, there is a minuscule theoretical speed advantage but only in some special circumstances and when it exists it would still be dwarfed by the debouncing delay.

It is impossible to say much much debounce delay a keyboard has without doing laboratory measurements... or looking through the microcontroller's source code ("firmware").
The firmware could also do stupid things that would cause delay.

Oh yeah, the Wooting... Really looking forward to some reviews on that.

And that '100,000,000 clicks' damn

i did some research on logitech romer g keyboards  but i couldn't find any 1000hz polling rate specifcation or any specifcation of polling rate but you're saying romger g is fastest of above?

capacitative...hm.. even cherry mx 6.0  realkey tech seems to be fast too

Fastest how exactly?
If you would measure from the start of a key press then those switches that have shorter actuation distance would have an advantage.

[czarek]

Just a reminder that day trading terminal keyboards, like those made for (not by) reuters or bloomberg are mostly built around Cherry MX Blacks. Of course you do realise that in places where those keyboards are used, clicks are worth a lot more dollars than your kills in LOL

I'M narrowing it down to novatouch tkl since wooting hasn't realease yet

I'm working based off of numbers from people who have done bump test comparisons (like from a user here or from Bloody, maker of optical keyboards here. Differences in travel can be compensated for by changing the height of each keyboard, but even if this were not done, it would not explain why Logitech comes out so fast, because the difference is too great. At the same time, if you look at Logitech's mice, you'll see similar results for many Logitech high-end models in click lag tests, some of which were done with direct wiring. Logitech almost certainly has a way of dealing with debouncing without introducing latency, perhaps by registering the change in key state right away, then remembering it and blocking future changes until debouncing in complete-- it's the only way to explain the data.

P.S. for OP: It's also worth repeating that Topre-style stuff comes out surprisingly slow. A NovaTouch comes in at 3-5ms according to Cooler Master themselves, and IIRC (I can't be bothered to find it atm, since the numbers came from a Chinese source and it'd take some digging to find it again) the RK capsense stuff can also take up to 5ms according to RK themselves. In other words, a regular mech with fancy debouncing will actually be faster than a cappy board-- but would still lose to an optical.

Novatouch is just okay, but if you plan on using one as is out of the box, I wouldn't recommend it. Plus, if you want one, you'd better act fast since I believe they are discontinuing it.
