This week there have been some movements in AMDs product portfolio. Not only did the chipmaker make some moderate price cuts, it also introduced a few new models as well as phased out some of the older offerings.
In the AMD FX camp, prices remained mostly stable, but some of the Vishera SKUs got their prices reduced. Given the current pricing structure, there is no incentive to buy the older Zambezi options which antiestéticature slightly lower performance. Alongside some of the pricing adjustments, AMD introduced two new AMD FX models based on the Vishera core. The FX 6350 antiestéticatures a 3.9 GHz clock speed with turbo up to 4.2 GHz and comes with three out of four compute units enabled, thus six cores. The FX 4350 is clocked at 4.2 GHz with a 4.3 GHz turbo and antiestéticatures two CUs (4 cores). In both cases AMD delivered a considerable speed bump over previous models.
When looking at Phenom II pricing, it becomes obvious AMD now officially retired the Phenom II X6 models based on the Thuban core. These models were already only scarcely available in the channel which means AMD stopped shipping them a while ago. Some of the quad-core models were phased out as well. Most prices remained stable but the Phenom II X4 965 Black Edition got another 11% slash. This makes this model a very strong bang for buck offering. If you don't mind missing out on some of the latest instruction set extensions, the time to buy one of those is now. Together with a suitable AM3+ mainboard and a decent graphics card this would be a capable midrange gaming system with the possibility to upgrade to later AM3+ CPUs should the need arise.
AMD also changed the pricing of some of it's A-series APUs. The midrange of their Trinity lineup gets some cuts as well as the older Llano-based offerings as well. In either case the low-end and fastest options remained stable, thus protecting against further price erosion. Interestingly AMD said in their last earnings call they were able to sell off some of the Llano inventory they had to write off last year. Llano will stay around at least till the end of 2013 as it seems now.
The pricing of the lower end Athlon II and Sempron CPUs didn't change in the last months. Some of those already saw considerable cuts the last time AMD made significant pricing adjustments.

Las Ivy Bridge-E de Intel, en Septiembre:
Report: Intel's Ivy Bridge-E CPUs Will Launch Sept. 2013
Report: Intel's Ivy Bridge-E CPUs Will Launch Sept. 2013

Intel's Ivy Bridge-E CPUs are likely to launch in September 2013, according to a slide from VR-Zone.
Previously, we were already aware that Intel's Ivy Bridge-E CPUs would be launching somewhere during Q3-2013, but now we may have a more specific date. VR-Zone has revealed a slide that shows that the CPUs are supposedly coming out in September 2013, among which are the i7-4820K, i7-4930K, and i7-4960X.
The Ivy Bridge-E CPUs would be based on a 22 nm lithography, and like any new generation, they antiestéticature a small performance improvement, as we showed you earlier.
The flagship i7-4960X would pack six processing cores and with HyperThreading antiestéticature 12 threads. It would have a base clock of 3.6 GHz, which will boost up to the 4.0 GHz mark. It has 15 MB of L3 cache and support for DDR3-1866 memory. All this processing power is made possible through a TDP of a massive 130 Watts.
CPU Model________Cores / Threads________Base / Turbo________L3 Cache________Memory________TDP
Core i7-4960X________6 / 12________3.6 / 4.0 GHz________15 MB________DDR3-1866________130 W
Core i7-4930K________6 / 12________3.4 / 3.9 GHz________12 MB________DDR3-1866________130 W
Core i7-4820K________4 / 8________3.7 / 3.9 GHz________10 MB________DDR3-1866________130 W
Based on the numbers given, we see the successor to the i7-3820K as the i7-4820K, and the i7-3930K is succeeded by the i7-4930K. Similarly, the i7-3960K is improved upon by the i7-4960K. What we don't see is a successor to the i7-3970X; however, we could assume that down the line, Intel might introduce an i7-4970X to top everything off. This is not shown on Intel's roadmap below, though.

Intel unveils Iris - its next-gen graphics tech
On-chip processor targets dedicated GPU gaming performance.
By Richard Leadbetter Published Thursday, 2 May 2013
It's safe to say that PC integrated graphics chips don't enjoy the most robust of reputations - a situation set to change radically with the release of Intel's fourth generation Core processors, code-named Haswell. Indeed, the firm is so keen to push the new graphics technology that it has re-branded its integrated GPU line, with the high-end parts now called Iris and Iris Pro.
Within Intel, the unofficial target performance of the Iris Pro part is to match or even exceed Nvidia's popular GT650M part, which marries up two Kepler SMX processor units with 2GB of GDDR5 memory. This chip is currently found in mid-range gaming laptops, as well as Apple's 15-inch Retina MacBook Pro - which may well be where Intel got the inspiration for the Iris name. To get some idea of what a quad-core Intel chip achieves in concert with the GT650M, check out our Retina MacBook Pro gaming review - essentially we're looking at the likes of Battlefield 3 and Crysis 2 running at 1600x900 with decent quality settings, representing a significant step beyond current-gen console. Achieving this level of performance isn't easy, particularly when integrated graphics chips tend to ship with no dedicated RAM and can only access DDR3 system RAM - fine for general computing tasks, not so good for gaming.
With the top-end Iris Pro, Intel's solution to the bandwidth issue is ambitious - alongside the main processor, there's a reported 128MB of ultra-fast eDRAM to provide the bandwidth that the system RAM can't produce. To put that into perspective, Xbox 360 uses a similar technique but only has 10MB of eDRAM attached to the GPU, while the next-generation Xbox - released later this year - has 32MB of embedded memory to do the same job (according to Microsoft's leaked whitepapers). eDRAM isn't cheap to produce, so only high-end versions of the Haswell chip get the extra memory - Intel's presentation suggests that it's just the quad-core mobile parts get the top-end GPU offering. Cheaper quads without the eDRAM are also available, and while there's clearly a boost to performance here over the existing Intel HD 4000, it's not quite as pronounced.

Reports suggest that Iris Pro offers performance similar to Nvidia's GT650M graphics chip, so what does that tras*late into in gaming terms? Here we see Nvidia's mobile GPU tech compared in two iterations - firstly in the 15-inch Retina MacBook Pro (which seems to run the GPU at higher than standard clocks) and then in the Alienware M14x. Both tests are carried out with the same 2.3GHz quad-core Intel CPU and resolution is at 1600x900.
The Pro-level part really flexes its muscles in the desktop arena, where clock speeds are significantly increased and where there's much more thermal headroom. Intel's 3DMark 11 testing suggests a 3x performance boost over the HD 4000 graphic tech found in the current third gen Core "Ivy Bridge" processors when comparing the existing 3770K to the new 4770R, while the new 4770K gets a 1.8x increase. So what's the difference between the "R" and "K" offerings? Well, only the "R" chips get the eDRAM, the traditional "K" processors utilise existing system RAM, giving some idea of the performance boost the dedicated memory offers (and perhaps by extension, why Microsoft needed it for its next-gen console with GDDR5 off the table).
Reports also suggest that the "R" chips aren't available as traditional processors that slot into a separate motherboard - these will be soldered directly onto the board and it's uncertain whether enthusiasts will be able to buy them at all, or whether the "R" chips will only be available to OEMs like Dell or HP. Intel is presumably betting - probably quite rightly - on enthusiasts sticking to their dedicated graphics cards in the desktop scenario. We've asked Intel to clarify to what extent the "R" line is available to those looking to build their own PCs.
So, what's Intel's strategy here? Across the entire market, it enjoys anything up to a massive 85 per cent share in desktop and laptop processors. However, OEMs often pair up Intel processors with AMD or Nvidia graphics cards, simply because the GPU horsepower isn't there in the integrated solution. With Iris and Iris Pro, Intel is making its GPUs far more attractive, potentially share-stealing from Nvidia/AMD and offering significant power efficiency savings in the process. So perhaps Apple won't need to go to Nvidia for its next Retina MacBook refresh - it'll have the power it needs in an all-in-one solution.
Here's how Intel HD 4000 shapes up against Iris and Iris Pro in the mobile quad-core line. The shaded line shows what the top-end chip can do when given more thermal headroom.
There's no chance that Iris Pro can make it into low-voltage ultrabook processors, but the increase in graphical performance at a lower TDP is suitably robust while the new 28W part should be quite impressive.
In the desktop space, Iris and Iris Pro have much more thermal headroom and presumably run at higher clocks, making the increases much more impactful.
We see something of a similar strategy in the ultrabook space, too. Regular readers may recall that Intel HD 4000 struggled somewhat to provide decent gaming performance on more modern games in the Surface Pro tablet, based on an ultrabook ultra-low voltage processor. Even in the higher-end mobile chips, HD 4000 wasn't exactly an exemplary performer, bested by AMD's Trinity APU. The new Haswell line for ultrabooks provides up to 50 per cent of extra performance while dropping peak power consumption from 17W down to 15W - an impressive antiestéticat bearing in mind that the chip is still fabricated at the same 22nm process. However, curiously, Intel has also introduced a new 28W part that more than doubles graphical performance.
This might seem like a strange decision bearing in mind that ultrabook tech is all about power efficiency, but Intel is simply reacting to what the market wants. Once again, the aim here is to provide another option to manufacturers who combine Intel CPUs with third-party graphics chips - just as Acer did with its Ultra M3 ultrabook, which pared up a low-power Intel CPU with Nvidia's GT640M - with some impressive results. The new Haswell 28W ultrabook part should easily outperform current-gen console, but will probably end up being utilised in larger 14- or 15-inch laptops just like the Acer.
The arrival of next-gen Intel integrated graphics should also offer up bonuses in other areas. There are suggestions that the eDRAM Haswell chips may well be able to use that extra 128MB of fast memory as an extra layer of cache for the CPU when graphics tasks are not active. Compute tasks and QuickSync video encoding should also see substantial improvements too across the entire line, whether there's eDRAM present or not. In terms of the CPU component of Haswell, we should expect to see a relatively modest 10-15 per cent boost to performance, plus support for ultra-low power draw "sleep" states - a crucial addition for making Core architecture viable for mobile devices. Significant battery life improvements for laptops are also being mooted along with on-chip support for the highly promising - if under-utilised - Thunderbolt interface.
The Haswell fourth generation Core processors start shipping at the beginning of June.
