Gigabyte Inclui Recurso DualBIOS em Todas suas Placas-mãe

A Gigabyte decidiu incluir o recurso DualBIOS em todas as suas placas-mãe.
Este recurso envolve a utilização de dois chips de memória ROM com o
conteúdo do BIOS armazenado em cada um deles. Em caso de falha no primeiro
chip, o computador tenta iniciar a partir da segunda cópia do BIOS
armazenada no outro chip. Este recurso é especialmente interessante quando
o BIOS é corrompido durante o processo de atualização e/ou overclock.
Inicialmente apenas as placas-mãe topo de linha da Gigabyte possuíam este
recurso.

Intel Cancela Produção dos Processadores “Havendale”

A Intel cancelou os planos de produção dos processadores de 45 nm codinome
“Havendale”, que originalmente estavam programados para chegar ao mercado
no final deste ano, para se concentrar na produção dos processadores de 32
nm codinome “Clarkdale”, que deverão chegar ao mercado no primeiro
trimestre de 2010.

Western Digital Lança Série de Unidades SSD SiliconDrive III

No Boletim 829 nós falamos que a Western Digital, segundo maior fabricante
de discos rígidos do mundo, havia comprado por US$ 65 milhões a
SiliconSystems, uma empresa fabricante de unidades SSDs. Os resultados
desta aquisição começam a aparecer já que a Western Digital lançou esta
semana a série SiliconDrive III. Formada por unidades SSDs SATA-300 de
2,5” e 1,8” (velocidade de leitura de 100 MB/s e velocidade de escrita de
80 MB/s) e unidades SSDs PATA de 2,5” (velocidade de leitura de 85 MB/s e
velocidade de escrita de 60 MB/s), as unidades SSD SiliconDrive III estão
disponíveis em capacidades de até 120 GB. Informações sobre preço e
disponibilidade não foram divulgadas.

Erste Benchmark-Zahlen für den neuen Prozessor aus dem Hause Intel sollen gar nicht gut aussehen – möglicherweise geht Intel deshalb gleich zur neuen CPU-Familie Clarkdale über.

Wie Fudzilla aus der Quelle “Intel inside” erfahren haben will, gibt es herbe Probleme sowohl mit dem Memory Controller, dessen Leistung ausgesprochen dürftig ausgefallen ist, als auch mit dem Prozessor selbst.

So soll Havendale im direkten Vergleich mit einer Lynnfield-CPU, der obendrein noch ein Arm auf den Rücken gebunden wurde (zwei Cores deaktiviert, Taktgeschwindigkeit reduziert), ähnlich abgeschnitten haben wie Bayern München gegen  den FC Barcelona: Lynnfiled absolvierte die SuperPI 32M-Banchmark in etwa 16 Minuten; Havendale benötigte 21.

Was insgesamt so aussieht, als werde Intel sich ganz darauf konzentrieren, wenigstens mit Clarkdale etwas Ordentliches hinzulegen – Nachbessern bei Havendale dürfte wogl nicht in Frage kommen. [dieter]

Recently, Intel introduced a new series of CPU’s: the Core i7. This is the new architecture that follows on Core2Duo. AnandTech tries to look to the future of this new architecture in an extensive article, of which I selected a few highlights.

To summarize, this is what I thought most important in this article:

• Intel creates a difference in high-end and mid-range CPU’s. The series that recently got introduced now: Core i7 920, 940 & 965 are the high-end segment. The mid-range will come halfway 2009. Important to know is that these CPU’s will need a different socket and chipset, so you won’t be able to switch from one to another without buying a new mainboard.
  • High-end will use LGA-1366 socket, X58 chipset. (now the 920, 940 & 965)
  • Mid-range the LGA-1156 socket, P55 chipset,
  • This midrange segment has works with 2 DDR3 in stead of 3 for the high-end and uses DMI in stead of QPI which means that the GPU and CPU will communicate with each other directly, not through the chipset.

Here are some highlights from the extensive article:

• AnandTech: Nehalem Part 3: The Cache Debate, LGA-1156 and the 32nm Future

  • For further reading I’d suggest our first two Nehalem articles and the original Nehalem architecture piece.
  • By 2010 all of AMD’s mainstream and enthusiast CPUs will be quad-core with the ultra low end being dual-core, a trend that will continue into 2011.
  • within Intel, many engineers still feel like it (the cache) is too small for current workloads. The problem with making it larger is not just one of die size, but also one of latency. Intel managed to get Nehalem’s L2 cache down to 10 cycles, the next bump in L2 size would add another 1 – 2 cycles to its latency. At 512KB per core, 20% longer to access the cache was simply unacceptable to the designers.

• AnandTech: Nehalem Part 3: The Cache Debate, LGA-1156 and the 32nm Future

  • 
  • Three DDR3 memory channels, a QPI link to the X58 chipset and support for multiple GPUs off of the X58 IOH. The Core i7, as you know by now, plugs into Intel’s new LGA-1366 socket. But in the second half of next year, there will be a new socket for mainstream users: LGA-1156.
  • 
  • The close proximity of the PCIe controller to the CPU could mean some very interesting things for latency, if well designed Lynnfield could have the lowest latency CPU-GPU connection we’ve seen on a desktop PC. Whether or not that’ll actually mean anything for real world performance remains to be seen, I’d guess not
  • we won’t see Havendale until Q1 2010. It’ll start production in Q4’09 but systems won’t ship until the beginning of the next year. This does leave a hole in Intel’s Nehalem roadmap as there won’t be any Intel integrated graphics chipsets between now and Q1 2010, which should give NVIDIA ample opportunity to sell chipsets into the mainstream Nehalem market.

• AnandTech: Nehalem Part 3: The Cache Debate, LGA-1156 and the 32nm Future

  • The absolute highest frequencies will only be available in LGA-1366 packages and I’d expect this is where we’d see 8-core/16-thread Nehalem parts first (if not exclusively). We’ve already shown that the three DDR3 channels don’t really help for most desktop applications, but this could change when Nehalem moves to 8 cores. Overclockability may also be better on LGA-1366 as the CPUs themselves will be higher bins.
  • Intel is going to support both platforms, LGA-1366 and LGA-1156 for the long term, the difference will be in the type of processors enabled. LGA-1366 may end up being more of a high end enthusiast play, Intel indicated that LGA-1366 CPUs would be binned higher so you can expect higher overclocks and obviously higher top end frequencies.
