Yes, but will it play Crysis?

The fastest consumer cpu you can commonly get your hands on is an i7 3.3Ghz right? Pffttt, that’s nothing compared to what IBM has cooking up. Over at the IBM laboratory they are working a 5.2 Ghz chip, expected to be the currently fastest. The chip is expected to power high end mainframe systems for enterprises. Whatever it will be running, it will do it very quickly. Regular cpus with ONLY 2 levels of cache are sooo last year. Can you handle 4 levels? 19.5 MB of L1 cache, 144MB for L2 private cache, 576MB of eDRAM for L3 cache, and a whopping 768MB of eDRAM for L4 cache. All to ensure the main memory doesn’t get bogged down by running petty commands or instructions. First thing they are probably going to do when they are finished running all of their fancy benchmarks to impress potential buyers? Run Crysis. Extreme Tech

Intel to share MacBook Air tiny cpu’s with Windows platforms

This bodes well for non-Apple laptop makers. Not only will they be able to do it better but cheaper as well. Since most corporate users are Windows based users get used to seeing MacBook Air PC clones all over the place. (And maybe you will be able cut cake with it too)

“… introduced the company’s second-generation dual-core mobile processors for increasingly popular ultra thin and light notebook PCs.” That’s not what anyone would call a high-profile introduction, but the processors themselves could be used by any company keen to compete with the MacBook Air.” (link)

Intel’s stonewalling forces VIA out of the motherboard biz

VIA is now focusing on x86 processors and the integrated motherboard market, rather than chipsets for third-party CPUs.

Previously one of the best chipset makers for enthusiasts looking for high performance on a budget, VIA has told Custom PC that it now sees no future in making chipsets for third parties such as Intel and AMD.

Speaking to Custom PC, VIA’s vice president of corporate marketing in Taiwan, Richard Brown, explained that: ‘One of the main reasons we originally moved into the x86 processor business was because we believed that ultimately the third party chipset market would disappear, and we would need to have the capability to provide a complete platform.’ (link)

Intel chips vulnerable to bug?

Security researcher and author Kris Kaspersky plans to demonstrate how an attacker can target flaws in Intel’s microprocessors to remotely attack a computer using JavaScript or TCP/IP packets, regardless of what operating system the computer is running.

Kaspersky will demonstrate how such an attack can be made in a presentation at the upcoming Hack In The Box (HITB) Security Conference in Kuala Lumpur, Malaysia, during October. The proof-of-concept attacks will show how processor bugs, called errata, can be exploited using certain instruction sequences and a knowledge of how Java compilers work, allowing an attacker to take control of the compiler.

“I’m going to show real working code…and make it publicly available,” Kaspersky said, adding that CPU bugs are a growing threat and malware is being written that targets these vulnerabilities.

Different bugs will allow hackers to do different things on the attacked computers. “Some bugs just crash the system, some allow a hacker to gain full control on the kernel level. Some just help to attack Vista, disabling security protections,” he said. (link)

AMD rolls out 6 and 12 core Opterons

AMD has updated its server processor roadmap with single-die 6-core and dual-die 12-core Opteron processors. The new processors will be manufactured in a 45 nm process that will be introduced with the Shanghai quad-core later this year.

When Intel rolls out its Nehalem processors later this year, AMD appears to be better prepared than in late 2006 when Core began its triumph and until today pretty much wiped out all of the gains AMD Opteron has made in previous years. On the server side, AMD will counter Intel with the “Shanghai” quad-core CPU, which will be based on the current Barcelona technology, but will be manufactured in 45 nm and bring performance and power consumption benefits.

According to vice president Randy Allen, Shanghai will deliver about 20% more speed than Barcelona. While the chip will remain compatible with the current Socket F (1207) platform, the L3 cache will triple to 6 MB, 3-lane HT3 support will be integrated and DDR memory support will be extended to 800 MHz devices. AMD claims that the idle power consumption of the new CPUs will be 20% below their 65 nm counterparts. (link)

Military not happy about Apple’s chip purchase

P.A. Semi, the chip design company Apple picked up for a song, is best known for its super-efficient PWRficient processor, a PowerPC variant. One of the big customers for the CPU is the Department of Defense, which makes use of it in programs in every major branch of the military, and they’re not thrilled by the possibility of Apple ending production of the chips.

Ten defense systems, to the tune of $100 million in products over the next four years, use P.A. Semi’s PWRficient processor. On Monday, P.A. Semi told its customers they were being acquired and couldn’t guarantee chip supplies anymore. (Brings us back to the problem of obsolete tech in the military.) (link)

DDR3 memory may not be worth the extra $$

DDR2 or DDR3? Which to buy? If you’re the hardcore gamer, you’re going to pick DDR3 but hold on there. The performance boost may not be worth shelling out the extra money. According to TomsHardware there’s only going to be a minimal performance boost (1-3%).

“Our conclusion is very simple: you get the best bang for the buck if you stick to the mainstream of the memory market, which currently is still DDR2-800 or 1066, preferably at low latencies. DDR3-1066 and -1333 memory do not yet result in better performance, and so should only be considered by hardcore enthusiasts, who aim for maximum overclocking performance knowing that they will get little benefit for spending a fortune.” (tomshardware)
