Feeding the Beast: 2x Cache Bandwidth in Haswell

With an outright doubling of peak FP throughput in Haswell, Intel had to ensure that the execution units had ample bandwidth to the caches to sustain performance. As a result L1 bandwidth is doubled, as is the interface between the L1 and L2 caches.

L1/L2 cache latencies and sizes remain unchanged. The same isn't true for the L3 cache however.

    Anandtech being a hardware site,its more inclined to keenly flow hardware devices with new architecture and innovations. iphone brings in
    1, A new A7 chip design and a novel 3 core graphics core
    2, A new 3 microphone parabolic sound receiving design(which likely will become the new standard)
    3, A new sim tray design(which will also likely become the new standard)
    4, New sony BSI stacked sensor (the 13 mpx version will likely be the rage next year).
    5, The first time that we have a 32 nm LTE chip which will give all day usage.
    6, New thinner screen with incorporated touch panel and 100 % RGB

    I am not sure about samsung but can anyone enlighten me about S3's technical achievements?

    99.998% of iPhone users just don't care about that. Really they don't.

    Geeks like me who do, are too damn smart to sell our souls to the such a god damned, locked down and closed system to even bother to care.

    Of course a company that releases one device per product category per year as well as one with the greatest mindshare is going to have more articles.

    But what happens when you add up all Samsung phones against all Apple phones in a given year?

    What happens when you don't count the small blogs that only detail a small aspect of a secretive product but count the total words to get a better feel for the effort spent per company's market segment?

    I bet you'll find that AT spends a lot more time covering Samsung's phones than Apple's.

    This. I generally trust their editorial, but the focus on Apple prevails. One just has to read accordingly.

    Also look at any other Apple product review. They are all ridiculously in-depth with analysis about almost every single component in the product. Macbook Pro with Retina Display got 18 pages, the 3rd gen iPad got 21 pages. Don't get me wrong, I like a proper review with everything analyzed, but it's only the Apple products that get these huge reviews. But compared to those massive Apple reviews, it's like all other products are just glanced over in a hurry. The new Razer Blade got 9 pages. Asus Transformer Pad Infinity got 8 pages.
