Now let's talk 4x4. While latest news has left me a little disappointed, I'm still optimistic, as this is what I really want. 4x4 offers the enthusiast two sockets for, from the start, two dual-cores. Later they will offer quad-cores. Why is this worth it over going s1207 Opteron? First, it will allow you to use unbuffered ram, which is generally cheaper, lower latency, and many more options. Second, there will be more options on motherboards. Most, if not all, enthusiast motherboard makers have given praise to the platform, and will be making boards. This means not only better competition for better prices, but also better overclocking potential. 4x4 is also good due to AMD's Direct Connect technology over Hypertransport(HT) lanes. This will allow the sharing of each cpu's cache and memory. This alone will improve games, which are generally gpu bottlenecked, add to that more processing power for background programs, and the fact games are becoming multi-threaded. Intel just dosn't, and can't for that matter, have anything to compare. This is due out by the end of the year as well. All these we are to assume will benefit s1207 Opterons as well.
Now let's talk K8L. K8L is supposed to be AMD's new architecture. Let's not get into what's considered new architecture, we all know both companies are really just improving on their P3 and K6 architectures. What we are considering are major jumps in technology. K8L will add another set of instructions, fpu, ipc improvements, more HT links, updated Direct Connect, shared L3, and many other things. While nothing can be set in stone, if you don't believe it won't AT LEAST compete with Core2Duo, then you really are an Intel fanboy. And remember, this less than one year after Core2Duo's release, not the three years we had to wait on Core2Duo after K8's release. K8L will be on socket AM2, and of course, 4x4. It is also going to be the architecture when socket AM3 releases. Any cpu released on AM3 will work on socket AM2, as has been stated by AMD. K8L will be native quad-core, and won't have the possibility of bottlenecking from front-side bus(FSB) due to it's integrated memory controller(IMC). Not to mention when you have two quad-cores on 4x4, or up to eight quad-cores on s1207 Opterons.
