keyboard polling rate

[Anarchist420]

Does anyone have a list of keyboards that do >= 500 reports/sec?

My mouse's input is a little bit faster than that of my keyboard so I want a keyboard that does at least 500 reports/sec.

Probably a few, but if you think you can tell a difference, it's placebo.

Mice have continuous motion, keyboards don't. IE, pressing a mouse or keyboard button takes so long for you that polling rate really doesn't matter, but as you are moving the mouse around a lot, you want the beginning of the frame to be close to in sync with the last mouse position. At 125Hz, you could be, in some cases, almost a whole frame behind every few frames, at 60FPS, so the motion might be jerky/stuttery (think panning, in a typical in a 24FPS movie), which can screw with your brain's perceptions.

I believe ThermalTake eSports' mechanical gaming keyboard line is 1000 Hz. I just have their cheap "plunger" keyboard, which is 250 Hz. At 250 I notice no delay whatsoever.

If I can do my math right, PS2 can do 1500 keys a second.

The old ps/2 connector uses hardware interrupts to send data (not polled like usb). Or is there a maximum speed I wasn't aware of?

The interface runs at a relatively slow (for computer hardware) 16.7Khz. It takes 11 bits to send a key signal which is where the 1500 comes from. I don't believe so, but I'm not 100% sure if there is a delay between key signals.

I know I have heard of PS2 overclocking, but i'm not sure how far you can go with that.
