Rumor Roundup: Everything We've Heard on Desktop Haswell So Far, June 3, Box Art Included
A brief roundup of all the information that has come to light, through rumors or otherwise, regarding the upcoming Intel Haswell desktop CPUs.
The Haswell launch is so close that Intel has decided to count the time to release in nanoseconds, which unsurprisingly comes up with a fairly huge number of zeros that spikes our interest even further. For those of you who haven't been keeping track of all the rumors regarding the Haswell CPUs, we're hereby giving you a big roundup with all the believable rumors that have surfaced so far.
The CPUs will all be backed on a 22 nm lithography and feature either a GT2 (HD 4600) or a GT3e (HD 5200) graphics part. The chips with the "*R" naming will carry the GT3e GPU, while all the others will carry the GT2 part. Not only this, but the "*R" named CPUs will likely have a BGA (Ball Grid Array) socket instead of the LGA (Land Grid Array) socket.
The CPU's with the "*K" naming are unlocked processors that will have an unlocked multiplier as well as an adjustable base clock frequency. Previously, only the multiplier was unlocked. The maximum multiplier value tied to a 100 MHz base clock will be 80x; the maximum would be lower for the other base clocks. For example, the maximum multiplier for a 125 MHz base clock would be 64x; the maximum for a 166 MHz base clock would be 48x. Either way, in all three cases the maximum CPU frequency would be no higher than 8.0 GHz. Not only this, but the base clock is no longer tied to the other controllers; it is only for the CPU itself. Previously, adjusting the base clock frequency by as little as 7 MHz could destabilize the system due to affecting other controllers. According to Intel, this should make the CPUs easier to overclock.

The table shows all of the specifications for all of the desktop Haswell CPUs of which we are aware to date, as well as the MSRP's of eight of the processors.
Beyond these changes, a rumor regarding the CPU's thermals has also surfaced. Previously, most CPUs have the die soldered straight to the IHS (Integrated Heat Spreader). This way, the heat could easily be transferred to the surface of the CPU. However, with Ivy Bridge, Intel decided to not solder the CPU die to the IHS, but to instead fill the cavity with TIM (Thermal Interface Material). As a result, the heat transfer was much less efficient, and the CPUs would run notably warmer. A report has indicated that the Haswell CPUs do have better thermals than the Ivy Bridge counterparts; however, it remains uncertain whether the CPU dies have been soldered to the IHS or whether TIM has been used.
In the meantime, VR-Zone has leaked an image of the box art of the Haswell CPUs. It looks like a CPU box.
Extrapolating the countdown timer shows us that the CPUs will be released starting June 3, 2013, meaning that they will be released during Computex 2013.

sundragon All this hubub for 5-10% performance improvement... Oh, memories of days yonder when AMD cracked the whip and intel jumped...Reply
I say this and I'm still interested, lulz -
This will be my next upgrade from my 2600k. But seriously who gives a rip about its integrated graphics. No one in their right mind cares about it either when buying these types of CPUs. When paired with a top of the line 2 dedicated GPUs (GTX 680s) in my case, you can't beat the performance. Best of the best. I'm hoping for a nice 20-30% boost over my current CPU. Or better.Reply

Starting to leak out slowly. Prob will be next month before any hit retail at earliest.10736198 said:When will we know about the Z87 motherboards?

vmem Hmm, for all current sandybridge "k" users, it looks like we're only looking at a ~20% increase at stock clocks (btw, do notice these chips are clocked higher at stock!) Eitherway I currently have my chip overclocked so I guess performance will largely how overclockable haswell is. remember how Ivybridge's bad thermals basically meant ZERO performance increase from an overclocked sandy part? T_TReply -
josejones So, Intel finally decided to stop including those crappy CPU coolers and either switch it for an upgrade or just leave it out completely and reduce the price by $20?Reply

DarkSable I still don't understand how Intel thinks that having an increased core clock... that is only tied to the CPU... is going to make overclocking any 'easier.'Reply
Surely people who are actually going to overclock know better than to see that as anything but market hype, yes? -

Perhaps you (and most gamers) don't care about IGP, but plenty of productivity-driven professionals whose primary concern is compute performance, not graphics performance, may indeed care. If the IGP is good enough, such individuals would have no need to add a discrete card of any kind to their machines to get their work done.
I don't feel Haswell's mild increase in performance truly warrants an upgrade for most Sandy Bridge owners, let alone Ivy Bridge owners. -
edwd2 At least, the processors are 5-7 dollars cheaper their respective ivy bridge counterparts on average, that aside, am i the only who thinks the box artwork is pretty bad?Reply
