Correct. The first instruction is a SSE1 instruction (move scalar single precision), the second one is a SSE2 instruction (move scalar double precision).Originally Posted by Bubba
I think they should have done proper detection of SSE2 - which they obviously haven't. SSE2 is pretty well defined how you detect it, so I don't see how they can have got that wrong unless they simply didn't do any checking at all [it either works or doesn't work on P4 as well].

Maybe they just do not support 32-bit Athlon XP's. The box says P4 or equivalent which usually means Athlons will run it. However some games like Assassins' Creed and others have started using SSE2 which immediately drops support for any 32-bit AMD CPU.I think they should have done proper detection of SSE2 - which they obviously haven't.
But there should be a method of identifying whether or not the processor installed supports the instruction sets required for the game to run properly and all of this should be checked when it is installed. Even if it's something as simple as identifying the processor name and checking it against a relational database. However, I'm pretty sure there is a more technical way to identify the instruction sets the processor supports.

Yes, the CPUID instruction will definitely identify SSE2 instructions.

On my bookshop I'm obliged to honor release dates. Most of the time I get the books 3-5 days prior to release date. My contract stipulates when I must put them up for sale. If I don't I broke the contract and should be forced to pay the distributor for damages.

Thinking about it that way, it would make sense that honoring the release date would be a clause in the contract that allows you to get the product pre-public release. I'm sure the manufacturer builds to order for companies with those contracts and that is an expense... so I could see them expecting those retailers to release on the correct date.

Well, if P4's support SSE2 and Athlon XP's don't, then they are not equivalent. I don't think they "failed" to mention anything. Equivalence is certainly not just in terms of performance and generation, but supported instruction sets as well?They are fooling people by saying Pentium 4 or equivalent. However they fail to mention that P4's have SSE2 but Athlon XP's do not.
They never said Athlon XP's are equivalent to P4's.

I explained myself poorly. I only have a contract with a few distributors. This contract was signed long ago. Since then I get the shipment and instructions for preferred placement and date (as well as minor stuff like if they want daily or weekly sales report , what is the return policy, etc). Failing a deadline on a top title is a major deal on this business and I would definitely have a lot of explaining to do... and no doubt be forced to compensate, since that part is clearly detailed in my contract.
For those other distributors with whom (sp?) I don't have a contract, we work on an orders basis. There's something I want, I order from them. Most of the time, I pay fully in 30 days. I rarely get the opportunity to order their books during release dates because there's simply not enough stock. Priority goes to their resellers, naturally. If I do/when I do, missing a deadline won't get me into trouble but is bad business and I will certainly not get a second chance.
...
I guess computer games should work on the same basis (I do get some software on my shop and it's the exact same thing). But selling centers like BestBuy drive so many customers that they probably can ignore a misstep here and there... or probably their contracts protect them better than I could ever hope with my small shop.

If they were told to expect 50 copies for the first week and they have 100 pre-orders to fill they don't loose anything from lost post-release sales in that first week.
In fact they may loose pre-release sales from those pre-ordered copies because some customers may cancel their orders and buy elsewhere from a store that did get more copies on release day than they had pre-orders for.
That's assuming the manufacturer buys the shelfspace from the store.Um...that is not the definition of a free market economy. If a manufacturer buys shelf space, car lot space, etc, etc, and you do not market their product in said space that does not fall under free market economy.
Usually that's not the case, usually the store buys the goods from the manufacturer and gets some promotional material (which they may or may not have to pay for) as part of the deal.
