This isn't even a contest. Check these comparisons.http://www.linuxhardware.org/article.pl?si...&mode=nocommenthttp://www.tbreak.com/reviews/article.php?id=356
The Intel EMT64 processors are 32-bit bit chips that are capable of handling some 64-bit instructions. The AMD 64 processors are true 64-bit processors that beat Intel to market by nearly 2 years, while Intel pursued the failed Itanium line. AMD is the only processor that is true 64-bit, and also runs 32-bit code just fine.
The Intel processor actually runs SLOWER on a 64-bit operating system. The Intel processor still uses a standard FSB.
Most of the benchmarks I've seen have the AMD's still spanking Intel of gaming, and cost considerably less. If you compare the entry level AMD 64 3000+ against Intel's entry model, AMD is $80 cheaper, and yet runs considerably faster.
There is also the heat problem mentioned in that first comparison. Without any overclocking, the Intel processor was overheating in a system with 4 fans configured properly. Yet, I know guys who have an Athlon 64 3000+ overclocked with a stock heat sink, running 2.6 gHz (a 30% overclock) on stock voltage.
planetamd64.com has plenty of these stories with screenshots as proof.
Lastly, many of those benchmarks use older AMD chipsets where the effective FSB is 800/1600. The newer NForce chipsets offer 1000/2000 effective FSB. So, I imagine if they were tested again on the faster chipsets you'd see an ever bigger lead for AMD.
So, one is true 64-bit, runs faster with a 64-bit operating system, has HyperTransport, runs cooler, kicks ass in gaming, and is cheaper.
How is that really a debate?
If you want a cheap, fast system here's what I recommend for those on a budget.Kingmax SuperRAM Series Dual Channel Kit 184-Pin 1GB(512MBx2) DDR PC-3200
- $103 for dual-channel PC3200 with good overclocking, and fast timings.FOXCONN "NF4UK8AA-8EKRS" NVIDIA nForce4 Ultra Chipset Motherboard For AMD Socket 939 CPU
- $114, which is $10 up from what I bought it at. This supports PCI-E, 939, 8 channel sound, firewire, 10 USB, NForce 4 (1000/2000) with built in gigabit LAN and built in firewall, SATA RAID (4 devices) and IDE RAID (4 devices). It comes with SATA cables and power adapters for all 4 devices, a hefty manual, and a mighty impressive BIOS.AMD Athlon 64 3000+, 512KB L2 Cache, Socket 939 64-bit Processor
For a budget system, the 3000+ is more than enough. I was just looking at benchmarks talking about overbuying your CPU. With a 6600GT, a 3000+ is more than enough processor. If you buy anything faster, you get diminishing results where you are throwing away money unless you've got a top end card.
Memory, board and proc come to $372.
Now, price a comporable Intel system. It will be much more expensive, and give worse performance for a gaming machine.
