Athlon Vs. Atom: Athlon 64 Is More Economical, Faster, And Quieter

Ambos são novos. Não tou aqui a discutir niveis de inovação.
Toda a gente sabe que é um K8, mas não deixa de ser um novo CPU especificamente alterado para um dado mercado.

Assim como um Core 2 Ultra-Low Voltage, não ? :rolleyes:
Se o A64 2000+ sozinho já é muito mais caro do que o Atom, e nem sequer vem com a motherboard incluída no preço, é basicamente o que isto é, uma CPU Low Voltage cara a ser comparada com uma CPU ULV do mais barato que há (~50 euros, com motherboard, em PT).

Mas depois dizem: "Ah, mas o Athlon 64 de 8W é muito mais rápido do que o Atom".
Basta apontá-los então para os Core 2 ULV, com TDP de 5.5W a 1.2GHz (ainda são 65nm), e ver quem é o mais rápido (já que o preço não importa, não é ?).

AMD Athlon 64 2000+ for Immediate Competition with Intel Atom
While AMD touted the Bobcat as a definitive competitor to Intel Atom, being a low-power K8 based part with the same design advantages its ancestors had over competing Intel parts when they made up for higher performing alternatives, this part won't make it until next year, enough time for the Atom to gain a stronger foothold in the market. As immediate competition to the Atom, AMD seems to have set an Athlon 64 2000+ single core processor as its ULPC / UMPC processor part. This processor is single core, features a 1.00 GHz clock-speed and 256 KB of L2 cache, which should still give it a performance edge over a 1.50 GHz Atom judging purely by the fact that the Atom isn't based on the Core micro-architecture (yet) and uses an older design.

This processor is based on the Lima core, what's most surprising is that it is found to operate at 8 W at its 1.00 GHz frequency which brings it into the Atom platform's energy domain. The second most surprising point is that this processor will be aided by the powerful AMD 780G core logic (chipset), as opposed to current Atom platforms using a i945G adaptation that has significantly higher thermal envelope as opposed the AMD 780G while being a lot slower (in terms of graphics performance and features). Tom's Hardware conducted a comparison between the two and found that the Athlon-780G combo "knocks-out" Atom-i945G technologically.

The AMD 780G uses a fraction of the power i945G uses and makes up for several features the i945G lacks. The only drawback as of now is that AMD hasn't quite been able to reduce the board footprint of these parts. Despite having double the TDP to that of Atom, at 8 W, the Athlon chip still remained comfortable with passive cooling. This opens up a new round of competition, of that between Athlon and VIA Nano which claims to have higher levels of performance / watt over Intel Atom. The first picture shows the processor itself, the second one shows the processor seated on a AMD 780G based motherboard made by Gigabyte, where the processor is made to be cooled by the stock AMD AM2 cooler with the fan removed, to study the effects of passive cooling on the processor.

O CPU testado pela Tomshardware é mais especificamente este:
http://www.techzonept.com/showthread.php?t=292418&highlight=netbook

não.

este cpu testado tem 512k L2, 128 bits de controlador de memória, HT de 1 ghz e socket 940. É um hibrido, portanto.

isso a 45 nm deve rular muito :D

A versão que a AMD vai lançar com uma revolução arquiturectural é o seguinte:

AMD Fusion graphics processor specifications exposure based on RV710 architecture built-in 40 operations unit

- AMD is expected "Kong" will be the RS780 IGP performance of 1.5 x or more, satisfactory performance.
- 128 Bit DDR3 system memory
- AMD adopted a new "Garlic" read the memory interface to reduce GPU system memory to read the information delay
- "Swift" will not use Hyper-Transport Agreement, but using code-named "Onion" the new interface
- highest power consumption is about 5 ~ 8W, idle time can be compared to 0.4 ~ 0.6W

Também é interessante indiciar suporte para crossfire-X entre CPU e provavelmente um IGP ou grafica low-end aproveitando sempre para aumentar performance caso haja algum outro GPU ATI disponível.
