You guys have no idea, how fed up am I of answering similar questions which pertains to availability of higher memory products r products with better usability etc. so, I recommend you all to go through the below given explanation and simple refer people to this post if you come across such questions because this is not only related to the product mentioned here but this applies to almost every product that is yet to be launchec, expected or rather hoped and wanted to be launched.
There has been seen a repeated confusion when it comes to the capability and availability of the product. Let us not mix them. People tend to come up with a rubbish conclusion that if a thing is not available than that doesnít work. Trust me when I say that is not at all the case. In fact, if ever things have been built then there has always been an option to sell it.
There is an age old and ragged concept of ĎCustomer is always rightí which is applicable only with the stock that exists and not with the other ones. When it comes to not-existing products then it is the companyís bottom line that matters to the company and not the client. Even before consideration of launching a product the company should feel that the demand is worth their investment. Every company wishes to make maximum sales with minimum risk and that brings them to business. That is their purpose of existence
Each and every company actually wait for the demand of a product to boost up so that they can invest at the right time and exploit the demand. However, being customers we are only concerned about what we want and only want to satisfy the unquenchable thirst for more.
But you can never expect them to focus on a couple of customers or even some dozens of customers. A company simply aims to cater the major portion of the target. There exists no company which can satisfy the needs and all of every customer that ever exists.
However, this is for you to understand the scenario better, a company will launch a product only in one of the three circumstances.
- If there exists hell lot of demand by a considerable amount of customersNow, that was a generic explanation which could be referred to products belonging to any category. Let us come to your specific question which speaks about GTX 690. Now, tell me what according to you is the reason behind the very use of GTX690 as merely a pair of GTX680. You think that is because it has been that way with the last five generations of dual-GPU cards, it is because most customers are satisfied with 2GB per GPU. Now, there is a hardly an amount of population which is unsatisfied with the VRAM and wants to have an 8GB GTX690. So, you cannot really expect a soon launch.
- If at all there is a considerable amount of demand by the customers which are actually paying really more.
- If the company plans and visualizes that the investment could drop the cost of development to a considerable amount. This happens only with the competition.
Two ways of getting more Vram on a graphics card:
1. use more chips (costs more power) or The 4GB GTX680's appearing now are using more chips because it is cheaper for them and they can charge extra premium for it, while the GTX690 uses the same chips as GTX680 tightly packed to keep the power consumption lower. I wonder if it wasn't worth the power consumption savings versus cost of using higher density chips instead on GTX690? It is each business' job to predict what tolerance the majority of their target customers have with power consumption and cost. Certain when the Quadro/Tesla versions with more Vram come, they will worth worth using higher density chips; we will see 8GB/16GB Kepler cards there.
2. use higher density chips (costs more money).
