There is only so much you can intehrate onto the CPU package before it becomes pointless. Cache, memory controller, Northbridge and GPU made sense, but little point using a FIVR when you are still stuck with using comparatively huge power supply circuits located right beside the chip.

What are y'all thoughts on the rumor that Broadwell EP/EX is getting skipped? http://www.kitguru.net/components/cpu/anton-shilov/intel-may-cancel-xeon-broadwell-chips-to-speed-up-arrival-of-xeon-skylake/

With how much Broadwell on desktop was delayed, it was always going to be interesting how Intel dealt with the server versions. Canceling Broadwell-EX is probably the right choice - it's better to make people wait a little longer for the major Skylake update than pissing them off by making them buy Broadwell and then release the follow-up much earlier than they expect (if they even buy it at all - people who follow their releases may well just choose to skip Broadwell anyway).

Do the -T CPUs use less power on an average / mixed workload, or just have a lower peak TDP but require a similar amount of total Watt-hours to execute a given workload? I guess I'm just curious if the low-TDP CPUs are made for thermal reasons or electricity efficiency reasons. What about the ULV notebook CPUs? Does it take an i5-5250u less total electricity to do a workload than say, a top-end desktop i3?

I guess I'm just curious if the low-TDP CPUs are made for thermal reasons or electricity efficiency reasons. This isn't always the case with laptop and embedded ULV chips, which need pretty much everything running below a thermal power envelope and the i5s and ULV i7s are often dual-core+SMT parts. However, the standard sized laptop Haswell i7 chips are binned for amazing overall performance per watt and as a result are higher priced per unit than most everything else for consumers.

Anime Schoolgirl posted:S and T CPUs are binned to run at high clocks-per-watt at significantly lower voltages, so it's both thermals and energy efficiency. The best part about those cpus is that if the iGPU isn't used at all, they pretty much run at full 4-core turbo all the time so you get balls-out compute power per watt (#1 reason why I shop for T chips over K chips like everyone else does).

http://www.macrumors.com/2015/07/24/intel-skylake-processors-leaked-slides/ I don't think this was posted since it seems to be published a few hours ago quote:The leaked slides reveal that Skylake processors will provide a 10%-20% CPU performance boost in single and multi-threaded applications, with lower power consumption, and 30% faster Intel HD integrated graphics performance on average compared to current-generation Broadwell processors. The improved energy efficiency will also result in up to 30% longer battery life. If true does this mean waiting for Skylake is a much better idea than most thought? Or am I a bigger idiot than I thought and this means nothing

Botnit posted:http://www.macrumors.com/2015/07/24/intel-skylake-processors-leaked-slides/ I'd assume those are cherry picked benchmarks to extremely specific workloads. It confirms what we expected, Skylake's biggest gains will be in the iGPU and battery life, exactly like Ivy Bridge, Haswell, and Broadwell.

go3 posted:because yall are seriously CPU limited I'm all excited about Skylake's lower TDP and getting USB3 ports vs. my 5 year old Bloomfield Core i7 930 @ 130 W TDP, but the fact of the matter is that this CPU is serving me just fine. Since I updated my PSU, HSF, case, and GPU earlier in the year, my system is both cool and practically silent. And I don't have any USB3 devices. Moving forward it seems like I only need to add more RAM, move to a larger SSD, and eventually upgrade my GPU again only if I run into games which are limited by my current setup. And yet, I don't game much these days AND I'm more frugal. It seems like my real drive to upgrade is mostly out of habit; I've never kept a CPU/motherboard/RAM combo for more than 3 years before now.

The only real performance-boner reason to get any new Intel chip these days is to see how much compute power you can get out of a low-TDP binned chip and Haswell was an immense improvement over Ivy Bridge in that part. I wouldn't hold my breath for Skylake doing a similar jump if they took out the FIVR out of their mobile and low-TDP models.

Nehalem was a hugely long lasting chip, but as someone that did the jump from an i7-920 @ 3.6ghz to a 3770 @ 4.5ghz, the performance increase was real. Not just video encoding, but in many games as well. I probably would have been fine to be patient and wait for Skylake since the jump wasn't hugely dramatic, in the 20ish FPS range from 45-65ish, (In cryengine games, which admittedly do like their CPU power), but my motherboard was getting seriously wheezy after a lightning strike came in over my cable modem and killed the onboard nic. Still probably going to build a Skylake system to try and further optimize my machine for silence.

At this point I'm holding on to my 2500K until they make IGPs that hit like my current good-by-2011-standards card. There's some PC exclusives that still call for that but are still worth playing if you don't have a 970 or whatever, and for everything else I've got a PS4 and I'm tired of chasing the graphics dragon.

I was checking around for BIOS updates on my work T430s (Ivy Bridge) and lo and behold, there was one from last month to "Support Windows 10" and patch a DRAM Row Hammer vulnerability (which I have no idea what they did -- I can see them modifying the MRC in the BIOS if Intel pushed a new release of that, or playing games with timings / caching / page tables, maybe Jawn or someone has a better idea). That reminded me to see if anything was around for my P8P67 PRO and of course not, last update was in 2012. Wonder if there will be some irritating, minor ACPI / EFI related bugs/glitches when I toss Windows 10 onto that machine. I figure for Lenovo, they want the trusted platform stuff, CompuTrace, AMT and other enterprise/business-class features to keep working, though I guess they could have also not done anything so corporate fleets would have to get new machines.

Could be unrelated but almost every mobo has BIOS updates in the last two months because the UEFI needs updated for PCIE SSDs
