GF100 (old fermi cards)

GK100 (current kepler cards)

GM100 (future Maxwell cards)

This means they started writing drivers for maxwell, and it means samples already exists.

Tesla acceleration drivers in 10.9
GeForceTesla.kext
GeForceTeslaGLDriver.bundle
GeForceTeslaVADriver.bundle
Don’t know what card they are for, Fermi based tesla C2070 didn’t used them.
Just a guess: It could be drivers optimized for computing, like there are some for windows. Maybe new Mac Pro will have not only the Firepro.

Sorry guys, its nothing about tesla cards, its just driver for older generation of geforce cards, gt200 aka tesla.

Let’s figure that out.

First, what is thunderbolt 2.

In thunderbolt 1, you had 2 lines of bidirectional 10 Gbit/s link, one for video and one for data.

In thunderbolt 2, these lines are combined, now you can get either 20 Gbit/s for data or for video.

That gives us 2.5 Gbyte/s.

now lets looks at pcie

 

PCIe Bandwidth Comparison (Each Direction)
PCIe 1.x PCIe 2.x PCIe 3.0
x1 250MB/sec 500MB/sec 1GB/sec
x2 500MB/sec 1GB/sec 2GB/sec
x4 1GB/sec 2GB/sec 4GB/sec
x8 2GB/sec 4GB/sec 8GB/sec
x16 4GB/sec 8GB/sec 16GB/sec


so, TB2 is a bit faster than pcie 3.0 x2 or pcie 2.0 x4 (talking about pcie 2.0 because true (old) macpros has pcie 2.0 links)

Now, if you want to know performance impact, open this link for a good article at anadtech and look for red bar.

In games, performance impact could be from few percents up to 40 percents. In opencl workload impact gonna be high.

1) The processor and RAM. There is only one CPU, and 4 ram slots around it, ram seems to be easily accessible.

Mac Pro processor

2) The disk. Their so called pci-e ssd is…. looks like some macbookpro ssd.

3) The GPU. There is two of them, you can see their backplates on sides of MacMiniPro

These things don’t look changeable.

Hence you will be able to upgrade memory and disk, but nothing else, sounds like mac mini.

According to it, bootargs is still 2.0, so current bootloader should work

The update is 10.8.2 with very fresh video drivers.

Nvidia drivers – 304.10.20f04

AMD drivers has acceleration support for 7xxx series (in amdRadeonAccelerator.kext), but no framebuffer driver for these cards.

P.S. no good news for 6970.

1) its gonna be beast mac, especialy 680mx, it’s just like desktop’s gtx680, just with lower clocks, ultimate gaming All-In-One computer
2) we will have better gtx670/gtx680 support
