Αυτογκόλ της Intel;

Intel and NVIDIA are at it again, but this time Intel seems to have scored a bit of an own goal in its ongoing war of words with its rival. The debate, as always, is "CPU vs. GPU;" a group of Intel researchers has recently presented a paper at the International Symposium on Computer Architecture (ISCA) that purports to demonstrate that NVIDIA's two-year-old GTX 280 GPU is not, in fact, 10X to 1000X as fast as the eight-month-old Core i7 960 CPU at key supercomputing workloads—it's merely 2.5× to 14× faster.

The Intel researchers claim to have tried their best to optimize both the CPU and the GPU, insisting that most of the previous tests that show a 100× advantage or greater for the GPU pitted optimized GPU code against unoptimized CPU code. A genuine effort at optimizing a kernel for both chips, Intel claims, narrows the gap drastically.

Unfortunately for Intel, it's actually not necessary to go deep into the weeds of the paper's specific claims and performance analysis to see where the company has blown it with this attempt to set the record straight. And NVIDIA's didn't cover itself in glory with its response to the paper, either. In short, silliness abounds in this mini-controversy, and both parties should be put in a time out.

Διαβάστε και πάλι αυτό που διαβάσατε. Δεν είναι λέει 10 μέχρι 1000 φορές πιο γρήγορα αλλά μόνο 2.5 με 14 φορές πιο γρήγορα. Το ότι είστε ρόμπες ξεκούμπωτες εκεί στην Intel δηλαδή δεν σας λέει τίποτα έτσι;

Εντάξει εν μέρη έχει δίκιο η Intel. Άλλο 1000 φορές πιο γρήγορα και άλλο 2 αλλά το γεγονός ότι όπως και να έχει, η NVIDIA τους πατάει (το ίδιο εννοείται και η AMD/ATI) στις συγκεκριμένες καταστάσεις, θα πρεπε να τους κάνει εκεί στην Intel να προσπαθούν να κάνουν καλύτερη τεχνολογική δουλειά απ' ότι καλύτερο μπλα-μπλα.

Για να δούμε. Θα κουμπώσουν εκεί στην Intel τις ρόμπες;
