On en parle depuis quelques mois, les nouveaux IGP Gen11 d\u2019Intel promettent beaucoup<\/a>. Intel a livr\u00e9 les d\u00e9tails techniques de sa nouvelle architecture. En augmentant de 166 % le nombre d\u2019UE (unit\u00e9 d\u2019ex\u00e9cution), Intel devrait plus que doubler les performances par rapport \u00e0 la Gen9.5.<\/p>\n\n\n\n

Une grosse \u00e9volution
<\/h2>\n\n\n\n

Comme pour la Gen9.5, les puces GT2 vont repr\u00e9senter la variante la plus commune. En effet, les GT2 \u00e9quipent tous les processeurs Core de 8e et 9e g\u00e9n\u00e9ration \u00e0 l’exception de ceux avec suffixes “F” ou “KF”. <\/p>\n\n\n\n

Le GPU Gen11 GT2 dispose de de 8 SubSlices. Chacun d\u2019entre eux contient 8 unit\u00e9s d\u2019ex\u00e9cution (EU), 4 unit\u00e9s de texture (TMU) et 64 Ko de m\u00e9moire cache. Cela donne au total 64 unit\u00e9s d\u2019ex\u00e9cution, 32 unit\u00e9s de texture et 512 Ko de m\u00e9moire cache L2. Quant au Slice, il profite de 16 ROPs et 3072 Ko de cache L3. Cela permet d\u2019atteindre une puissance de calcul de plus d\u2019un TFLOPS en FP32. <\/p>\n\n\n\n

Comparativement, sur Gen9.5 GT2, on retrouve 24 unit\u00e9s d\u2019ex\u00e9cution, 12 unit\u00e9s de texture, 192 Ko de cache L2, 8 ROPs et 768 Ko de cache L3 pour une puissance d\u00e9livr\u00e9e de 384 GFLOPS FP32.<\/p>\n\n\n

Niveau sp\u00e9cification, l\u2019\u00e9volution est donc tr\u00e8s importante. Intel triple quasiment le nombre de la plupart des unit\u00e9s, et quadruple presque la quantit\u00e9 de m\u00e9moire cache L3. Pour les personnes int\u00e9ress\u00e9es, la firme a publi\u00e9 la documentation technique de 33 pages<\/a>.<\/p>\n\n\n\n

Des am\u00e9liorations qui semblent se confirmer dans les benchmarks<\/a>. Le c\u00e9l\u00e8bre TUM_APISAK<\/a> a en effet post\u00e9 une capture d’\u00e9cran des r\u00e9sultats de la Gen11 dans Ashes of the Singularity. En 1920 x 1080 avec les r\u00e9glages sur Low, la Gen11 obtient un nombre d\u2019ips moyen de 20,4. Des r\u00e9sultats environ deux fois plus rapide que ceux obtenus par l\u2019Intel UHD 620 et comparables \u00e0 ceux d’un GPU GeForce MX130.<\/p>\n\n\n
