HD chips are underpowered

[kill or be killed]

HD has 25% more power than comperable mix hardware. At 48k you're gonna get about an extra plug in per chip. At 96k You're gonna get 62.5% of what you would have had on a comperable mix set up (with the same number of cards.) Also that means, at 96k, without plugins being able to span multiple chips, some plugs aren't going to make it and others are going to have deminished performance. Extrapolate this to 192k and you get the idea. HD sounds great, but i see a revision coming on. The way mix came to d24.

Could I put all 18 compressors on one channel?

How many dsp farms do I need to have 32 channels with 18 compressors on each channel?

Sure, get creative with auxes. I'm sure it'll sound great.

You need 32 HD farms at 96kHz or 16 HD Farms at 48kHz. Of course, I recommend 96k when you use way too much compression. It helps to balance the gratuitous excess.

Sure, it'll cost around $120,000, but it's far cheaper (and friendlier to the environment) than paying for the electricity required to power 576 hardware compressors. Not to mention the added cost of all those rack screws.

Erik, I love it. [img]images/icons/grin.gif[/img]

-but stop posting and get back to work on those HD upgrades! (any chance we'll see a few before your "officially posted" ETA?

Doesn't seem underpowered to me, and it also seems like way more than 25% more.

Opening up a 44.1 session (final mixes) that I did on MIX4 (one core, three Mix Cards) with enough channels/plugins to pretty much max out my four Mix cards, .... opening this same session on my HD4 system didn't even light up anything on my 3rd and 4th HD Process cards.

As Erik alluded to, this seems to me like twice the DSP power.

I also like to add that HD has SRAM on every chip, so in the case of SRAM hungry plug-ins usually many more instances are possible. For example, in the case of DVerb you can get 6 on Mix and 18 on HD (9 at 96k).

They are underpowered and as things go
not really that needed with all the chip sharing problems and the many new host based
plug-ins around.

Instead of getting that extra card...what you really need is afaster mac

It's not quite that simple.

For example, you get 18 Bomb Factory compressors on a MIX Farm. You get 36 on an HD Farm, which is twice the performance.

At 96K you get 18 compressors, same as a MIX system.

Thats encouraging.
