Default New TDM and old TDM.

For example: The power that one would have with a mix3 is equal to which of the new HD cores? Or is even HD1 more powerful than a mix3? If so then, wow...I'll bet the HD3 then is lovely!

At 44.1k a new card is almost exactly twice as powerful as an old card. At 96k the new ones are about equal with old ones that are only 44.1k or 48k.

HD1 = 1 card (twice as powerful as Mix)
HD2 = 2 cards (twice as powerful as MixPlus)
HD3 = 3 cards (twice as powerful as Mix3)

Now, is that double in terms of plugin instances on a chip? Will I get two Ampfarms or two Reverb Ones per chip?

Dave,

There are 50% more chips, and each chip is about 20% more powerful. I wouldn't guarantee twice as many plugs on a chip.

But all of the chips are now "A" chips, so Reverbs on every chip if you'd like.

Nika.

Unfortunately, you will only get one Reverb One per chip. The new cards are about twice as powerful as the old cards, but the new chips are not twice as powerful as the old chips. The difference is made up by having more chips per card. Since Reverb One completely maxxed out an old chip there is not enough dsp to get two instances on a new chip.

However, as Nika said, all of the new chips are SRAM chips. Since Reverb One can run on any of them you can actually get 9 Reverb Ones per card with HD instead of the 3 per card you could get with Mix.

Yes, which bodes the question of how plugins that take up a whole chip currently will be able to manage at higher sample rates. Will Reverb One be able to function at 96k? 192k? etc.

Frederick?

OK, so let's take a plugin like Analog Channel that doesn't use an entire chip. Will I get more instances? Are the new chips more powerful at all?

The reason I ask is I probably wouldn't need higher sample rates right now. I'm happy at 48k. I also don't need a large track count. What I do need is power for plugins.

Default Re: New TDM and old TDM.

Each DSP is 25% faster than on MIX, plus as mentioned above each DSP has SRAM (with twice as much as the SRAM DSPs on MIX). So, plug-ins will have 25% more DSP instructions at 48kHz, and memory-limited plug-ins using SRAM will be able to use up to twice as much SRAM. in other words, yes the chips are more powerful. Of course, it will be up to each plug-in as far as how it might take advantage of the increased power. Regarding plug-ins using a whole chip at 48kHz, they may not be able to run the same algorithm at 96kHz without some modification (some modification may be necessary just for 96kHz, regardless of how much DSP is necessary). ReverbOne for example needed to be modified to run on a single chip at 96kHz. (Thanks to Frederick ;-)
