被YY已久的AMD Bulldozer原来是K6堆起来的……

Bulldozer將採用K6架構﹐2011年登場


Bulldozer將採用K6架構﹐2011年登場
-------------------------------------------------------------------
據Plannet 3Dnow! 德國網站報導﹐新的Bulldozer核心將回歸採用K6架構。

相對K6架構﹐Bulldozer有如下重要的改進﹕
2 X 64KB L1每核心
256KB L2 每核心
8MB L3 總共16個核心共享
浮點單元相比K6採用獨立的ROB
Cache讀寫帶寬高達512Bits
16個核心的Bulldozer的面積(包括1-3級緩存)僅僅是140mm^2﹐45nm
支持SSE5
6級流水線﹐意味着更少的分支錯誤所帶來的性能的損失

至於該網站報導Bulldozer將于2009年登場﹐但是經過我向AMD相關知情人士了解﹐目前AMD計劃在2011年才推出Bulldozer核心。

原来是K6难怪这么废

这个跟LZ 的文章一样搞笑吧。

45nm Phenom? It's called the Phenom II and you Get It Next Year
Phenom II will be available in a couple of versions. The Phenom II X4 is a quad-core part initially released for the Socket-AM2+ platform, but eventually it will be a Socket-AM3 part with DDR3 support. The Deneb core is a Phenom II X4 with 8MB of L3 cache and the Propos version has a 2MB cache. Both of these cores have integrated DDR2 memory controllers, with a transition to DDR3 sometime in 2010.



Caspian is a dual-core version of the 45nm Phenom II with a 2MB cache, Champlain hits in 2010 and is a quad-core Phenom II with DDR3 for the mainstream notebook market. Geneva is a lower powered 45nm dual-core product, presumably Phenom II as well, due out in 2010 for ultra portables.
AMD also revealed a bit of its 2011 roadmap; these products are based on the first new architecture since Phenom - called Bulldozer. I talked about Bulldozer a while ago but details have been scarce since then.

In 2011 AMD expects to be at 32nm with its Orochi, Llano, and Ontario cores. Orochi will be the new high-end enthusiast desktop product with more than four cores, more than 8MB of cache, and an integrated DDR3 memory controller. Remember from the server roadmap that in 2011 AMD will have four DDR3 memory channels on its server products so I'd expect at least a 3-channel DDR3 controller here.

Llano is the mainstream 32nm part with four cores, 4MB of cache, DDR3 memory controllers, and an on-die GPU. Note that this is a delayed introduction of the first CPU/GPU fusion product, originally scheduled for 2009. AMD stated that the plans for the first CPU/GPU products got pushed back simply because the 45nm designs weren't compelling enough. The dies get small enough at 32nm that you can actually offer tangible benefits. Note that this also means that the first single-package CPU/GPU will actually come from Intel in 2009 with a Nehalem derived part and not from AMD.
Finally we've got Ontario, which is a very low power core based on AMD's upcoming Bobcat core. It's a dual-core product with 1MB of cache, on-die GPU, and a DDR3 memory controller. We know even less about Bobcat, but I did write about it over a year ago.

这个早就被证明是假新闻了

被证明是假新闻？

我是抛弃了MMX200买了个K6-2/450在用，至今仍在服役。

K6-2/450的游戏和多媒体性能，比MMX200好不了多少，不过整数确实比较强，当时配128M内存跑WIN2000速度相当快，MMX200想跑WIN2000就慢死了。

K6??? 当初抛弃166MMX，买了个K6 200，超到225用

逍遥不是仙

大家别看不起K6，现在的肉不就是个P3改么，说白了也就是和p2一个胚胎出来的

哎，都没看出来那个是愚人节笑话啊

从multi-core到many-core的改变，并不是越新的构架越好啊

现在家里还有一块K6III 450{shocked:]  浮点还可以，整数不行呀

K6的浮点對當時的AMD來說是一個痛{lol:]
不然為何K7出來的時候AMD一直強調浮点的改進??{titter:]

倒了吧，k6系列的整数运算一直是它的强项，和同频的piii相差无几，不过浮点运算就差了几个台阶了

所有的U不都是基于8086出来的么{closedeyes:]

那扣肉还是P3架构呢…………{mellow:]

K6连P2都打不过，怎么跟P3比{lol:]
