Nu börjar det dyka upp allt fler rapporter från vanliga användare om den nya iMacens prestanda, men tyvärr inga riktiga benchmarks än så länge.
Bra spelprestanda i Warcraft:
"It loaded fast, and when the first character popped up in town, the frame rate never dropped below 60, and this was pretty much going full tilt in the settings."
Enligt en användare på Appleinsider:
"Okay, I currently have some Google Maps mashups open in Safari (we're doing real-estate searches), with iTunes streaming CBC Radio 3, and I played the X-Men 3 trailer in 1080P, zoomed to fit width (it was too large otherwise).
CPUs were evenly loaded, and ranged between 25-50% usage while all this was going on. No frame drops were visible. Scrubbing was smooth. I don't have QT Pro."
Helt okej prestanda i Photoshop:
"I had a chance to spend some time on one of the new 2.0 GHz versions of the Intel-based iMac in Apple's booth on the show floor this morning. While it was far from fully loaded with third-party software, it did have Adobe Photoshop CS2 running on it. Several quick tests showed that the software, running in emulation via Apple's Rosetta technology, performed adequately in processor-intensive tasks. For example, resizing a 4,000 x 4,000-pixel image to 16,000 x 16,000 took fewer than 10 seconds to complete, and resizing back down to 4,000 x 4,000 took fewer than five seconds. Various filters performed pretty much the way they perform on dual G5 CPUs."
Ännu en användare på Appleinsider:
"All the native apps ran well and even Photoshop CS ran fine under Rosetta. They didn't have any good sample images so I loaded one from iPhoto and blew it up to 600 dpi and Photoshop ran decently. I might go back tomorrow with my own files so I can test it out further.
The machines also played 720p HD QT movie trailers very well with minimal hit to the CPU. My guess is that the H264 decoding is running on the graphics card.
Safari ran well and did a good job opening multiple simultaneous tabs.
The machines boot fast. The startup chime is unchanged but appears slightly later in the boot process... there's a slight delay between power on, the screen coming on, and then the chime.
The one complaint I had was with iTunes. I took an existing music track that was on the machine and "converted" it on the machine. This is a CPU bound task since it wasn't ripping from a CD. On my G5 I can get about 24x encoding but these new Macs topped out at 6.5x. My guess is that it can't use altivec and can't use the GPU so it is running as fast as it can on the plain CPU. Granted this wasn't a scientific test. If you were ripping from CDs though I doubt you'd notice a big difference."
