Delta U.
Quick comparisons and facts.
Clean overall design, it is a decent website to get a quick estimate of a products performance and specifications. The comparisons are a little weird sometimes and don't always represent real world performance but it's to be expected with hundreds of different products with many different combinations. There doesn't seem to be a major bias in the comparisons but there is a slight skew towards Nvidia when it comes to GPUs. Overall it's a nice quick check but definitely shouldn't be used as the only resource in researching products.
