Which is faster, 845G of P4X333?

[sean2002]

I seen reviews where the two are the same, where the 845G leads by a small margin and where the P4X333 leads. So for once and for all which is faster?

Hard to say how it pans out in real life, because the P4X333 boards have not reached the market yet.

P4X333 is ahaead by 5% or so, and that puts P4X333 5% or less slower than 850e+PC1066 in all but one becnhamrk (Comanche 4) . So, prefferable is P4X333, but no boards hyave hit, so, but 845G is solid as well

The VIA is ~ = in performance to the 845G in Anands benches. It was faster in some, slower in others. The i845x boards also have the ability to lock PCI/AGP speeds in spec, which makes them ideal overclockers. 845G is also a rock solid chipset. VIA?

Here is what Anand said about the performance delta:

While the 845G and P4X333 swap positions once again the performance difference between the two is intangible.

Although VIA has had much more experience in producing DDR memory controllers than Intel, the 845G's GMCH is able to offer performance equal to VIA's finest DDR333 memory controller. This is one of those situations where sheer R&D budget can outshine production line experience

Under Quake III Arena we're able to see the largest lead the P4X333 ever holds over the 845G. At 4%, the performance advantage isn't enough to be even remotely noticeable to end users.

Our final two benchmarks paint a similar picture to what we've seen throughout this entire review - the 845G and P4X333 are effectively performance equals

The 845G and P4X333 are the highest performing DDR chipsets for the Pentium 4. The two solutions perform very close to one another however the 845G wins out because of the fact that you'll find it in more motherboards than the P4X333, unless VIA can surprise us with a tier 1 motherboard manufacturer. Since the P4X333 does not have any integrated graphics the price of P4X333 boards should be noticeably lower than 845G boards but given that the 845G GMCH is manufactured on a 0.18-micron process the integrated graphics shouldn't add too much to the price of the chipset.

Soltek has P4X400 board out (although basically a P4X333 board with some more features)

VIA's DDR memory controller is more mature than Intels, and offically supports PC-2700, which Intels does not

Yeah, but it works perfectly. I'll take a stable platform even if the PC2700 support is unofficial (for now). To each his own.

P4X333 is faster, but where are you gonna get one? I've been wanting one for a while, thought about buying an i845G board, but probably will go with an i850e board. Like Anand said, "If only they had a license"

Here is the most recent regiew of VIA's answer to the P4X333 motherboard.

Seems there were some problems getting a 1.6A to boot to 133 FSB - apparently they are still working on the southbridge combo.

The delay in releasing this board has to be a stability issue - I've not seen VIA delay like this, even when stability was questionable.

And has for the Intel license...I'm sure they're very concerned.

This review by vr-zone clearly demonstrates the 845G (Abit BG7) to be faster than the P4X333 in most instances. Infact it is almost as fast as an 850E/1066 rdram combo given a high enough fsb. I can personally vouch for the BG7's great performance since I own one and have been very pleased with it.

 

[oldfart]

Anands review said the same. I dont know where the P4X333 is faster than 845G idea comes from. Its not true.

 

[Mark0999]

With a 400Mhz P4, the P4X333 would be faster. Most of the P4X266A and 333 reviews I have read have stated the inability to get the FSB to 133Mhz and beyond. The is a huge problem!

Huh? The 1.6a is a 400 mhz chip and it goes well beyond 133 fsb on an 845G (unoffical ddr 333 platform).

No, it would not. Only thing you will get by going VIA are the problems that are so well known with VIA chipsets. Dont forget the lower IDE performance as well. Cant see a reason anyone would consider one.

 

[OneOfTheseDays]

the P4X333 mobo is the fastest benchmark performer. In some instances it even trounced the RDRAM 1066 P4T533 combo. Check back on the anandtech news and read the review for the Asus P4t533 and 32bit rambus modules and they have the P4x333 compared.

 

[oldfart]

Last review I read, they couldn't get the VIA board to even POST over 128 FSB. What a joke.

I already posted above Anands review comparing it to the 845G. Its not faster. Why bother with VIA? I'm kind of partial to stable chipsets, but thats me. To each his own I guess.

Even if the P4X333 is faster in benchmarks (which it isn't), the differences in performance are minimal and wouldn't be noticeable in real-life applications. I'd much rather get a chipset that is tested and *works* and *is available*.
