News sur les Z77 Panther Point chipset

Z77 Panther Point chipset

PCI-Express Graphics : 1x16, 2x8, or 1x8+2x4 Gen3

Total USB Ports : 14 ( 4 usb3 )

Total SATA : 6 ( 2 6gbps )

The only major differences between the consumer chipsets is in the support for PCIe lane configurations as well as SRT. All are set to be released in 1H’12, but they may not all launch at the same time. For example, with Sandy Bridge Intel released P67 and H67 initially and will follow up with Z68 shortly.

In terms of feature support, Intel will allow overclocking in all non-business Panther Point chipsets and will support the IGP on all the new chipsets. That means there will be no direct replacement for P67 (not that it really matters), and similarly there’s no direct equivalent of the non-overclocking H67. This is good news as quite a few people were annoyed by the lack of a “do everything” chipset for SNB (though Z68 should fix this). The display options are also improved relative to SNB/Cougar Point, and now support up to three independent monitors instead of just two. We suspect most users who want to run that many displays will benefit from a discrete GPU, and it’s also worth noting that with SNB CPUs in 7-series boards you will be restricted to two independent displays.

The biggest improvements are in the I/O segment. One long-awaited feature that’s coming in Panther Point is native USB 3.0 support. Many people were disappointed when Intel decided not to include it in Cougar Point, forcing motherboard manufacturers to use a separate USB 3.0 chip. All Panther Point chipsets will have four USB 3.0 ports which is actually pretty nice, considering that most of the current motherboards only come with two USB 3.0 ports. There are already many USB 3.0 devices (mostly external hard drive bays and flash drives), and with the added bandwidth USB 3.0 offers it’s already moving into the mainstream market. Though some rumors reported Panther Point would include support for Thunderbolt, there is absolutely nothing in the current roadmap to suggest its presence in the 7-series chipsets. There’s always the potential for motherboard makers to use a separate chip to add Thunderbolt, but that could be done with any current platform.

Another interesting I/O update will be PCI-Express. As noted earlier, Ivy Bridge will upgrade PCIe from 2.0 to 3.0, which means twice the bandwidth—or a move from 500MB/s to 1GB/s per lane. This is very good news for users who want maximum graphics performance, meaning SLI or CrossFire, but it also helps with technologies like USB 3.0 and SATA 6Gbps. Sandy Bridge and LGA1156 Nehalems (Lynnfield and Clarkdale) have been somewhat limited by PCIe bandwidth in multi-GPU configurations since they had to share 16 lanes. That meant either one GPU at the full 8GB/s bandwidth, two GPUs at 4GB/s each, or four GPUs with only 2GB/s each (using dual-GPU cards).

We investigated this back when Lynnfield launched; while the performance difference was negligible in most games, there was a noticeable FPS drop in some games, especially in quad-GPU configurations. Of course, today’s GPUs are even more powerful so the limited bandwidth could be a bigger deal if we reran the test with the latest hardware. However, Ivy Bridge should abolish this bottleneck as the bandwidth will be double once more. This means a single x8 PCIe 3.0 slot can provide as much bandwidth as an x16 PCIe 2.0 slot, i.e. 8GB/s. The same applies to quad-GPU configurations as an x4 PCIe 3.0 slot will provide the same 4GB/s bandwidth as x8 PCIe 2.0 slot. This implies that there should no longer be a loss in GPU performance when running multi-GPU configuration on Intel’s mainstream platforms, though obviously you will need a GPU (or other PCIe card) that supports PCIe 3.0 in order to utilize the faster speeds. We don’t have any information yet about AMD’s or NVIDIA’s plans for PCIe 3.0, but historically they have been ready when the motherboard support is there.

The business chipsets support two additional features. Q77, which is the high-end chipset, will support both vPro and SIPP (Stable Image Platform Program). Q75 will not support vPro but it will support SIPP, whereas B75 will not support either of those. All of the business chipsets also include native PCI support, which is still important for many companies that have custom peripherals.

ça c'est deja vu sur d'autre board...

Watchout les bench avec 2Xmoins de IO que les vrai SATA...

Je sais que ça s'est déjà vue ... mais Gigabyte semble l'offrir sur un bonne partie de sa game de Z77.
