is there anyone here running either the new macbook air i5 chips other latest macmini's using lightwave?

so graphics, are they stable on the mac mini or new macbook air for opengl?

is the i5 intel chip in the new macbook air multithreaded?
is the mac mini dualcore multithreaded?

any insights or comments welcome!
btw i'm also looking at the imacs!

thanks in advance!

No sir I regret to inform you they are not hyper-threaded regardless of whether you go with the i5 or i7, I got burned like this last time I upgraded my my MacBook, thought if it's i7 it's had to be even though the spec sheet at the store didn't mention it, I learn't the hard way that unless they state explicitly it is it ain't. Fortunately they say just that for the new top end MacBooks so I ordered one woohoo !

hi just to get a visual on how various apple macs will perform for rendering scenes vs cost i made this chart.

also included a cheap windows 15" laptop to compare with the macbook pro's

yes that Acer looks good but it's a great big plastic lump of a thing with a real low res screen (1,366x768), even the old MacBook Pros or most PC laptops will have a 1680x1050 screen or better even a 1960 x 1200 and I don't know how you're benchmarking it but CNet gives it an overall Geekbench of 11,391, the MacBook Pro gets
13,535 and as for battery life both are rated around the seven hour mark but CNet reckons the Acer should be a more realisticaly rated at around 59 minutes, and finally I can plug a raid drive in the MacBook Pros Thunderbolt port for video editing which is something you couldn't do with the Acer

Acer looks good but it's a great big plastic lump of a thing with a number keypad unlike the macbook pro's:D

my simplistic assessment is just cpu speed times number or cores and time hyper-threading if there is any on the cpu.

What is the difference between hyper and multi threading?

I've been using a i7 mac mini since last september and it seems to perform at about .7 of the rendering speed of the 2008 Macpro it replaced. It does 4 threads, the server which costs 100 dollars more has 8 threads but there could be issues with the OS when running LW (?).

hyper threading is for chips like the intel i7
4 actual cores [threads] - multi threading
plus 4 hyper-threads making a total of 8 threads.

note also that i5 intel chips do not have hyperthreading...except SOME dual core i5 chips do have hyperthreading like my friend's new dell laptop so he has 4 render buckets with modo 601 for example not 2

Which is why I have a bluetooth numeric pad, ok the Acer is amazingly for the money if not too portable and has a better graphics card than the new top end MacBook Pro, bloody Apple half the time think they're a money grubbing bunch of bastards who'l screw you for every last penny and the hype for the new line totally OTT for what it is but still I know which machine I'd rather have.

Using Scazzino's benchmark:

2 x W5580 3.2 GHz (25.6 GHz total)

Hyperthreading on 16 threads
2h 58m 51s (10731.3 seconds)

Hyperthreading off 8 threads
3h 59m 43s (14383.9 seconds)

So with HT on a render will be done in about 3/4 of the time.

Apple numeric keypad, one could gaffer tape it to the side of the laptop!

Why would you go for a mac mini or air? They're not equipped with nvidia cards last I tried my collegues systems. You'll have big problems with opengl in lightwave dealing with point selection and transparency.
I wouldn't go for apple system unless its a macbook pro which has an nvidia card. But then I'd rather get a big plastic lump that's half the price thrice the performance. :D

Not just no numeric pan, but no keys! Absolutely brilliant for Lightwave!?

Macbook wheel!

i'm not interesting in the macbook air..so no need for a chart for myself!:D
